BTB on a Cammed VTS...

  1. #1
    Is there a benefit other than it sounds amazing?

    Cant help but think perhaps the diameter is too wide?

    Do you think I'd get better performance from the car if I was to swap to say a Magnex system?

    Karl.
  2. #2
    You won't know until you test... But in theory, yes, it's too big. Maybe all the boxes help keep the back-pressure up. 2" bore should be more than enough.
  3. #3
    I wondered about this too
    you need some back pressure in the system
    I would say a 2" might be marginally better but it might not nessecerily mean more power

    I had a similar setup with a supersprint and piper exhaust (similar manifold too)
    and had similar power to your car
  4. #4
    Ive just put my standard exhaust on for the mot and i can tell you there is a huge difference with that

    IMO it goes well with a cammed vts, but its down to you really, if you changed exhaust I cant see you noticing any difference between them.
  5. #5
    If you're really that interested, I've got a Scorpion full system you can *borrow* and test the differences...

    as in its shed loads better with the BTB?

    Awaits Ryan its awesome totally awesome

    If it was me..it would be off...flogged and replaced for a system thats best suited
  8. #8
    at least you reccommended another system lee..

    oh, wait

    yes alot better

    You have two option here, listen to people with BTBs and Cams, or Leeroy, whose not got either of them.
  10. #10
    I was considering keeping it just for the noise, it rocks.
  11. #11
    i honestly thought i wouldnt notice a difference going from that to standard, its had it on for that long and with the cams, i couldnt remember what it was like, thought there isnt goin to be much difference at all, but there is a huge, just isnt as much pull

    And you might have actually got over the 150 mark if hadn't used the btb.....tbh 147bhp..i wouldnt even bother!

    3bhp makes alot difference ... LOL

    i have seen vts's making 157 bhp etc on a good supersprint exhaust..

    No need for a btb on a cammed engine only...
  15. #15
    going back to standard makes loads of difference regardless of uprated camshafts or not.
    I have gone back to supersprint centre and standardbackbox as i sold the piper when i was going to sell the car.

    Feels restricted as hell and sounds ghey as hell.

    Ran really lumpy to start with.

    Its personally what you feel your car runs best with.
    Someone has offered you a loan of an exhaust give it a try if your not too fussed about swapping them.

    also will make a tiny difference to what your car was mapped with.

    Rons VTS has some random exhaust i dont evne know what it is, think its a powerflow backbox. but it still made 155 on the rollers when it was mapped with the ph3's. And is very quick tbh

    Its all trial and error mate see what you find best.
    How did you rate your last system you had on the VTS which was the same as mine bar i have standard manfiold and cat in place.

    where as mine matched rons on the straights and his is that magical over 150bhp, as your a huge expert you would realise that different RRs make different powers.

    Lee, you have no experience with BTBs or Cams, its like me making a comment on an evo
  17. #17
    Theoretically after the rear collector if all is done right it will really not matter what you have done as long as its not restricting. So you cant really go to big on the actual back part of the exhaust if the test is sorted. Though odd of that are slim to none.

    I aint owned cams or a btb orrect...but when you were trying to make you vtr as fast as a vts I owned a gti and at that time 3 of my good mates had there's cammed...one ran a btb changed it for the supersprint and power made more power and torque

    Make your mind up is it faster or not

    Ron doesnt have a diff or xsi box and yet he is still faster.......ohhh and he doesnt run a BTB..so really all that money you spend hasn't gained you anything at all has it

  19. #19
    Catcam 708's for me and BTB 4-1 Manifold and Exhaust.

    162bhp on the rollers.


    To be fair the difference between any aftermarket exhaust is virtually pointless arguing over when the difference will easily be made or lost anyway depending on the quality of the mapping.
  20. #20
    quite a big difference between Yates and Willsy yet they have practically the same setup.

    Too many other factors along with the basic cams, mani, and exhaust.

    Fuelling (I have larger injectors - i dont think Yates does)

    Engine itself (Mines only got just over 1k on the clock after being fully reconditioned)

    ECU and Mapping (not sure what Yates has currently) But i think the big difference comes here
  22. #22
    Oh yeah, yours is standalone?
  23. #23
    But different rollers Karl thats the difference.

    LOL ask Ron who was faster through every corner. ask him if i caught up to him when he was around 1/4 a track ahead. Im sure Ron wont mind sayin. Ask Ron if he wants a diff and xsi box, the answer is yes, we have chatted numerous occasions about the diff lol.

    i never tried to make my vtr as fast as a vts lol. Im not sure why your telling me you had a gti when i had a vtr either, as that still doesnt mean you have had experience with cams or a btb. Wow your mate had one, my mate has a dc5, doesnt mean im an expert on them. The difference is that i run a cammed vts day to day so i have experience on both, you dont.

    I helped to pick the bits he used and went to the mapping time with Chipwards and Dave Walker

    Along with helping to build a TB'd engine.. I think I have plenty....

    I use my own experience..

    Car you use everyday

    "its just a track toy and doesnt drive it every day"....and your going to be back on the boat soon ( there is a god) so hardly a day to day car

    How did I guess you two would be in this thread bickering?!!!

    From everything I have read and heard about bore sizes, the BTB is designed for high output saxos (tb, tutbo, sc), however as I've never owned one I can't really comment on it's "comparable" performance.

    If it were me though Karl, I would be cashing in on it and sell it on to fund something like the OMP Inox SS system. Can't imagine that sounds too shabby

    i totally forgot about that inox system.
    Love the sound of them and i like the looks.

    Get a very good review, i dont have one as not sure on the db level as there is no silencers.

    BTB does weigh a tonne too, already killed a set of exhaust rubbers after only 1,000 miles. Upgraded items needed

    Cleared for Group N use so will be within usual db requirements.

    Looks sexy as fook, light as fook (which is better than adding a few bhp!) and under £500 notes brand new

    Very true Leeroy, to start getting the best out of it, spec could do with being at a TB 180bhp+ level id have thought.

    Still one of the best systems out there whichever way its looked at

    Al post the spec sheet up if i can find it again.

    tbh Ryan I thought you were Ginger, but that is off topic so I refer to my original point.

    Sell the BTB and buy a much lighter OMP Inox

    you realise you quote in sig says i had him in corners cos of the diff, which you said he was faster in corners?

    ive been off for a month and used the car pretty much every day, so its been an every day car

    im away soon there is a god? i know your glad of that, means you dont have to pretend to be on the phone or stare at the floor every time im around

    The BTB is to big for simple cams and by the sounds of it a few people agree..so pointless having it and spending cash on in it

    perhaps you should go to a better opticians


    And as for a BTB, I ran one on my standard vtr (contraverisal) I gained better mpg aswell as the car was a better drive in comparrison to 3 other exhaust set ups I ran on it, mixing standard rear boxes with uprated center pipes, to full systems.

    You cant fault the quailty of the system, again compairing it to systems ive run. Personally I would keep it, no one has the cash to put their money where the mouth is so you wont get alot of ££ for it in todays enviroment.

    some interesting views on the BTB here,

    leeroybrown i take it you favour the likes of supersprint on standard / cammed s engines then?
  58. #58
    My honest opinion is to stick with the BTB. Its inevitable that at some point you will take the tuning of your car further than cams (I keep telling myself im not) and at which point you may have to change system to a BTB. If id had the money Idve had one, as it is my exhaust is made up from a magnex decat, a magnex centre I got free and a custom back box from AAS (NE fabricator)
  59. #59
    Inox system looks pricey! dont look bad,
    Yeah Steve that is my old one.
    Mixed opinions whether its worth keeping BTB or not then.

    considering lee, Ive actually owned the item, so post an opinion based upon that.

    Which you disagree with HAVING NEVER OWNED ONE!

    Perhaps if you didnt try making pot shots at members for no apparent reason you might not have been banned as often as you have...

    its all down to personal opinion. Like I said I did get better MPG aswell aswell as the car did notably perform better.

    I guess you can listen to those who have had them, or those who cant afford them so will allways like to bitch about them

    I personally cant stand the raspy noises of the Ashely or the Supersprint and OMP systems use, they are all sound and no go to me.

    I dont have a link. But when I was out on Sunday the 2 lads I know with them, one has a silenced section one doesnt...the race system is raw as hell...but with the silencer it does sound wicked...not raspy at all

    in comparison to my other systems the car ran better and I got more miles from a tank.

    I only took it off because it was going to be used on my other engine, and I couldnt justify having the two btbs I had in use, so wanted a standard system on the saxo for daily driving.

If id had the money Idve had one, as it is my exhaust is made up from a magnex decat, a magnex centre I got free and a custom back box from AAS (NE fabricator)
    Quoting meself so it isnt lost in amongst nonsense

    Makes sense I suppose, the diameter is a bit large but if you guys dont think im losing any power through it then I suppose ill leave it on.

    For the hassel of buying another system and changing it for the sake of 5bhp max, would you bother?

    If they didnt sound as good as they do, or suit the rear bumper so well then i wouldnt have bought mine purley because of the size, however they look the tits and when on a spirited drive, it doesnt sound like a gay chav cannon. Its just a nice exhaust noise

    ask yourself a question.

    Are you tryng to chase every 1-2bhp. As if so you then will want to have the head ported to match the cam choice, valves chosen to suit etc...

    imo theres nothing wrong with the system, Its a good ground for more work if you chose it, built very well so will last (something you want in an exhaust) and does still perform well even on a standard 8v (as mine did)

    You could sell it for another system but then how much money do you expect to get for the BTB, and then the cost of a new system and swapping them over etc..

    reason a btb is so good is its bhp figures it gains on boosted cars, an after market exhaust at 2" bore is a decent exhaust on cams or standard recplacment, a btb is designed well from what ive seen/been told about them.

    but a 2.5" bore is NOT needed if your not much above standard power and in MY opinion on a cammed car only producing 30% more power than standard a btb isnt needed because your cheaper after market exhaust or standard exhaust wont be restricing.

    Boost.. well oviously a car doubling bhp isnt going to breath well on standard bore size, hense a btbs size and design helping make good amounts of bhp...

    but if i was offered a btb at cheap price id have it, other wise i would rather put the money towards other things.

    all IMO...

    Dont forget a BTB has 2inch first section lads!

    obviously the BTB will help power as you get higher up in the revs as the increased flow wont be as restricted. all depends on where you want your power!

    Love the sound of them and i like the looks.

    Get a very good review, i dont have one as not sure on the db level as there is no silencers.
    Don't know if its makes a difference now!

    But i have the OMP INOX on my 16v.

    I haven't driven the car with it on that much, but it made a hell of a difference from my standard exhaust, even with my shit manifold.

    And its nowhere near as loud as i expected!

    Don't know anything about the BTB to comment.

    i get really good MPG as well!!

    i think its because of my scorpion back box.
