Rattling Baffles / Exhaust Mod

[vroom]

Toying with the idea of having the silencer modified on my Chim.

The main reason for this (besides the noise)is that the baffles are rattling at idle & it really is starting to p*ss me off.

The question is how can the baffles rattle when the box essentially consists of peforated thu pipes and a load of cladding??

Are there baffles in the tale pipes?

If I gently tap the tail pipes, I hear the rattling around the centre section of the exhaust (i.e. silencer). Would hate to get the mod done only to still have the rattle.

Pls help!

Cheers,

Nick

The baffles inside my box were loose due to broken welds. These, along with the wadding, were removed completely. It now sounds soooooo good. Dont hesitate to have it done !!

Slikk,

Did you have the internal pipes removed completely or were they replaced with solid pipes in the silencer???

Removed completely. The silencer is now a very empty box. No apparent reduction in performance, but it still has the cats to give backpressure.

Could be small stones in the exhaust. Not sure how they would have got there unless someone was being cheeky.

I was thinking that too. Could well be peanuts from the monkeys I have living next door to me...

So whick is the best mod to do, sleeve the perforated pipe or do as you have and remove completly.Don,t want to do anything which will affect performance or do some other form of damage. Thanks

Don't forget the other option:

Cut out box completely & replace with 2 pipes. A small bracket is then welded accross the 2 pipes to cater for the hanger that was part of the original box.

Well, the emptied box would sound more boomy at about 3k revs which got irritating (it did for mine). With the 'normal' pipes replacing the perforated pipes it sounds more in yer face without the boominess. (I'm sure I've said this before )

As for the last option I don't know, but it should still sound the same as replacing the perforated pipes.

I have to be honest and say that when cruising on light throttle, the noise doesnt seem to be any more intrusive. Under acceleration, however.. .. .. ..or overrun come to think of it.. .. ..

Go for straight thru pipes inside the silencer, looks nice and normal....but has the right sound track, if you know what I mean!

....then the main cat?

My 1995 4.0 is going under the knife tomorrow... for the straight through pipes inside the silencer.

It's my 28th birthday, what a cool present eh? To myself!

How much is that setting you back?

[verysideways]

Cost 70 quid and worth every penny.
Bought Steve a 6 pack to say thanks too.

Car sounds awesome, would thoroughly recommend, but you should be aware that it ain't quiet... i'm loving it! Burbles at lower revs and HOWLS between 3k and 5k.
