Hi all! If I take off my centre section of my exhaust, will I loose power? I have a full Magnex s/s system and GMC 4-1 manifold!
Centre section!

#1
-
#2what take it out all together??
-
#3Well so I have basically a Magnex backbox, whatever make centre silencer and GMC manifold! Looking at something like Remus,Supersprint centre section!
-
#4Or could I just get the centre box off my exhaust cut out and get a straight pipe welded to it?
-
#5if you have a full system, no point taking it to bits. wheres your cat?
-
#6It was in the manifold until I took the manifold off for a GMC 4-1! It was quite loud with the open filter but now I have a Green enclosed its gone quieter! I wasn't too bothered that it's quiet at first but I just miss that bit of noise!
-
#7why do you want to take the centre section out? noise or...
-
#8Yeah, just that extra little bit of noise! If i'm going to loose performance then i'll leave it on!
-
#9i dont know if im reading this wrong. do you have a full magnex system or just backbox?
-
#10I have a full system! Just want to loose the centre box because it's too quiet!
-
#11kk. no harm in doing it. i would have done this if i didnt already run a full system.
-
#13Might just get the centre box cut out and weld a pipe to it! Seems a waste if I take the whole thing off!
-
#14the only other option is to sell the whole lot. get a new backbox and supersprint section
-
#15Has anyone ever heard of a Cybox exhaust? Are they any good? Just found this, just wondered wether it would fit to my GMC 4-1 manifold and Magnex backbox? http://cgi.ebay.co.uk/NEW-SAXO-RACIN...QQcmdZViewItem
-
#16never heard anything bad about them, there are a few on here with full cybox systems and say they are good
-
#17mate has a cybox backbox, it sounds pretty good.
-
#18Right ok! Might get one then! You think it will fit my car?
-
#19You want a supersprint one, to make your car sounds like this

#20Where did you buy that from mate? Did it fit ok? Also is it louder than in the video?
-
#21we have ordered a few supersprint centre sections. Should be delivered to us in a few days
-
#23love the sound of that as alwaysQuote:You want a supersprint one, to make your car sounds like this

#24If I change the centre section to a Supesprint will the engine management light come on?
-
#27no mate that only happens on the new saxo vtrs where there is a lamda sensor in the cat/after the cat to check its working.Quote:If I change the centre section to a Supesprint will the engine management light come on?
they are easy to fit, took me 20 mins with fannying around getting the clamps to seal properly.
is your car stripped out? if it is the whole car resonates at around 3k rpm and its proper loud inside.
i will try and get an internal video so you know what i mean -
#28The cat is in the manifold on mine! However I have a 4-1 manifold on it. So i have one lambda probe in the manifold and one probe in a sleeve! So it should still be ok should'nt it?
-
#29yes, you can the longer of the two supersprint center sections that will extend to where the CAT is on mk1's. Ill find a pic in a mo to explain it better
-
#30Ok thanks mate!

i've put 233002 on a 01 vtr. the only thing with supersprint is that they are full systems you need to match the centre section with one of there exhausts -
#32What do you mean mate? Do I have to buy one of their backboxes?Quote:http://www.supersprint.com/homeuk.htm
i've put 233002 on a 01 vtr. the only thing with supersprint is that they are full systems you need to match the centre section with one of there exhausts -
#33yea you need to match supersprint mid to supersprint back box
-
#34they have discontinued most of their backboxes. The one single pipe one they do is the 100mm one!
-
#35So theres no way of me being able to fit the centre section to my Magnex backbox?
-
#36i want to know too lol if they do fit then i'll start stocking magnex
-
#38supersprint center section fits fine with janspeed backbox
-
#39Have you heard wether it will fit a Magnex mate?
-
#40This is the exact same system as mine! Looking at this, does anyone know of any type of centre section to fit this backbox? As I am hoping to get the centre section tomorrow!
-
#41Anyone?
-
#42you can get a single box magnex system from abp motorsport. taking the centre section out wont effect performance mate, less restriction and better flow for the gasses. will defo make the car louder

#43I am taking my car to Demon Tweeks on wednesday! They are making me a centre section and make it fit to my Magnex backbox and manifold, so will be an exact fit!
It's a Powerflow centre section! Cant wait for it to go on!
-
#44Anyone think Powerflow are any good? I know they are not the best, but it's only the centre section after all!
-
#46I haven't had a quote yet! They said it shouldn't be too much at all because I have bought quite a few things off them anyway! Will let you know tomorrow if it's done by then!
-
#47Have just got my car back! Sounds great now! Really pleased with the way it sounds and how much difference it has made to the performance! Will post a vid soon to show you all how it sounds!
-
#48better perfomance mate and has it lost some power lower down as im thinking of doing this
