HELP! 1.0L standard exhaust way too loud?!

4th October 2011, 15:13

( Just realised this should be in the Problems & Queries section. Could a moderator move it please? Sorry! )

Right, had a sound problem with my car since I bought it and I need to get it sorted. I have a 1.0L saxo and it's quite loud, especially on the motorway. Exhaust system LOOKS basic (oval down-turned end pipe), nothing looks after market, but it has to be because it's very loud compared to a standard 1.0L.

I don't know much about exhausts, but all of the sound is coming from the tail pipe. If I cover the exhaust tip with my hand, the exhaust goes DEAD silent, and the car sounds the way it should be. I guess this points out that there's no blowing holes in the system.

I'm not paying £150+ to replace the whole exhaust system, as a new standard back box didn't fit the pipe that's on there now.. so is there any other way I can quieten it down?

Help

No, everything in the engine is completely standard. It's just the exhaust.

Cats broken up or baffles in back box have failed.

As I said a standard back box didn't fit. The previous owner told me he had the exhaust system fitted for the sound, so nothing has broken.

Which brings me back to how do I make it quieter, without replacing the whole thing.

Still got the cat in? might not be in hence louder with std backbox... or a hole on the joins.

Already said that there's no holes, and I'm not sure about the cat. Like I've said, this new exhaust was there when I bought it and I don't know much about exhausts to tell. I'm just wondering if there's a simple way to make it quieter that doesn't involve getting a new exhaust system. Is it simple to check?

I has not cat and a backbox with no baffles in it, the sound is amazing and i love it

4th October 2011, 21:42

If the original back box doesn't fit them your a abit stuck, Have you got the standard back box? there's a centre silencer box pipe on ebay pretty cheap.

so theres an aftermarket system on the car fitted by a previous owner?

either find a baffle to fit in the end (very unlikely as you said its oval) or get on ebay/breakers yards and try and find a 1.0/1.1 of the same age (as the exhausts changed layout of where the cat is with age)

either way it will more than likely be a new exhaust system

Damn, was hoping some other solutions. Your right with the aftermarket exhaust - the only way I know is that, apart from the fact it's brand new, the standard back box wouldn't fit.

I was hoping there would be solutions to fitting things on the tail pipe, etc. Not sure what else to do.

Get some pics up of the system and the join for the centre section and backbox, we can probably help more then.

5th October 2011, 01:50

With it being oval would it be the phase 1 vtr back box? Is it just a short tail pipe that looks like it's been stuck on the end?

Well the center section & back box join looks exactly like this (but brand new):

..and the back box looks exactly like this:

These are images from the net, but I can remember what it looked like quite well.

Thing is, I know how to fix it. Replace the whole system with a 1.0 or a 1.1 exhaust system. Simple, I know that - but I'm after any other ways of making it quieter without spending a lot of money to replace all of that.

5th October 2011, 10:43

The thing thats confusing me, is your title states its a standard system, then some of the posts say its aftermarket, but those pics are of a standard(rotten looking, but standard none the less) system, thats why I said post pics of yours as i'm really confused lol.

I can't however of a way to quieten it without changing exhausts, does your centre section have a silencer in? If not maybe get a large one welded in.

That's my point, I'm just as confused as you. It LOOKS completely standard, which is why I'm thinking it must be altered - maybe the silencer's taken out or something. But if it's standard, why didn't a standard back box fit it? Honestly bud I'm just as confused.

Looks bog standard throughout, doesn't sound standard, standard back box doesn't fit. AARRGGHH!!

That's why I can't really pin point what the problem is

Like I said, the one way I know that will rid all of this is to get a new exhaust system completely, but how much would that cost to buy and fit?!

5th October 2011, 10:57

thats exactly the same as my 1.1i and it is irritating at 3000rpm on the motorway

does it sound like this when just reved?

YES. A lot like this! But I know I haven't got any holes in the exhaust because as soon as I cover the tip, the noise goes completely.

And yeah, same as you. Motorway driving is a pain in the arse.

Maybe you've either got a vtr centre fitted to it and bought a 1.1 backbox,or have you bought a new backbox not for your 1.1?I'm not sure if they are cross compatible although i'm sure people put 1.1 centre sections on VTRs?

Like I say is your centre section silenced or not? Have a look as you could put a silenced one in there, or maybe if theres weld marks and no silencer it might have been removed.

The best bet is probably replacing the exhaust system from the cat back, get searching eBay I think they are cheap enough, and easy enough to fit if you have basic mechanical skills.

I haven't bought anything - I haven't touched the exhaust. I took it to a garage to get a new standard back box fitted and it wouldn't fit the rest of the pipe, which made me think it was after market.

It's also a 1.0 not a 1.1 (if that makes any difference). How do I check if it's got a silencer, and how & where can I see it?

actually you may have hit mine on the head its seems i dont have the same center section as the standard 1.1i and that is a solid peice from flexi to back box where as mine is split in 3

so that could be i have a vtr exhaust on it then

op has yours got more sections

Its probably a cheap as cheaps copy of the oe system. If poorly made the wadding could have fallen apart or something.

5th October 2011, 12:05

Hmm, could be! Either that or he's put a new exhaust on and took the silencer / cat out.

Could you tell me where to find the cat or silencer, and how easy it is to check? Would be so much cheaper and easier if I just need to put one in rather than getting a new system.

5th October 2011, 15:30

Just stop being tight and replace the system, noone on here is going to fix it. If its to load turn ur music up or something failing that replace it.

Stop being tight? Either you could spend over £100 for me just to quieten it down, or stop being so rude. I've got other priorities to spend money on and other things I need to save up for.

This was meant to be for suggestions to make it quieter without doing that, and everyone's been a great help - apart from you.

Just had a look at this thread, I think my center pipe looks a little different than yours. I think something may be missing?! Either way I'll take it to a garage - there's a local one by me who I know pretty well, maybe they can tell me what's missing.

5th October 2011, 16:47

take some pictures of your actual exhaust mate...

and when you first start the car up look underneath see if theres any leak from joins... (may not be sealed properly)

at a guess bar holes, you either have no cat (straight pipe > backbox) or your backbox is knackered.

with yours being a mk1 you only have a cat and backbox afaik. the mk2s had cat >silencer > backbox?

5th October 2011, 16:57

might just be loud. my 1.1 always was

£100!! a centre pipe costs like £30 brand new
can probably pick up the full system for £20 second hand off someone on here id imagine.

physically check for air leaks around all the joins though. Just putting your hand over the end isnt going to help much

nothing wrong with a loud exhuast though

mines unbearable on the motorway but i love it!

5th October 2011, 21:08

Theres some guy in cwmbran selling a whole exhaust with the curvy tip for £15

6th October 2011, 09:39

Thinking on it, I'm pretty sure it was just a straight pipe to the back box... I'm guessing that would be why :O I wouldn't quote me on that though, will have to double check.

If it's cheap to get another exhaust then I might as well get one fitted! I must admit it does sound nice around town.. it's got this warble when you put your foot down to pull off, and isn't too loud. It's just the motorway driving really!

I took it to a garage and he said to get just the backbox and fit it, it'll be £56. That was the cheapest as well!

just fit it yourself it is just a matter of a couple of bolts, and as the system hasnt got studs built onto the pipes if you shear a bolt just replace it

i know what you mean about the noise on the motorway it is really irritating its just a loud drone above 3000rpm

you could just go down the route of sound deadening the boot tho and still keep the noise around town

Good point. My boot has no boot lining - I literally had to use cut up carpet (which, to be fair, I've done a good job XD) so that may have something to do with it.

Lol the previous owner - Builder, smoker, pet owner and VERY untidy. The car was a state when I had it, but underneath all of the plaster, dust, wood, hairs, fag ash, you could tell it just needed a clean.

ANYWAY - I'll price up an exhaust system and some proper boot lining! Good ideas
