Exhaust Tapping Noise

[NICNAC]

I have noticed a little tapping noise on the rear end of the car when biting the clutch around 2000Rpm or under,
so i jacked the car up for a better look and found 'tie raps' around the exhaust rubber mountings

the Exhaust is hitting the diff as circled in the pics.......

Has anyone else ever had these symptons?

If so, is it a case of the exhaust mountings being knacked and needing replaced or the bushes on the Diff/Rear Subframe needing renewed

Or could it be a poor quality Replacement Exhaust?

i now Fancy going for that S/S exhaust mentioned in the other thread (£210euros)
Anyone any ideas
Cheers
Steve.

exhaust clamps.....

And tie raps

Steve: tie wraps are a very good solution against ageing rubber hangers, as it prevents them from becoming loose and letting the exhaust bang wherever it can (although yours does already).

The proper hangers on a UR-quattro exhaust system are steel links surrounded by rubber. Never tried fitting them on an S2 system - nor do I know if the proper S2 items are also re-inforced like this.

ar those good old chain encased in rubber mounts, they were the business!! alas audi in the infinite wisdom dropped them about 2 years ago which was a real shame as they were soooo strong!! but they were also sooo expensive!

[NICNAC]

is this a normal thing then?, Could i just buy poly bushes or standard ones to replace the tie rapped ones?
Has anyone else had this problem before????

My heatsheild on exhaust rattles upto 3rd gear past 4k rpm?

dosnt bother me but pple give me weired looks when im just kicking into my turbo.. been told some liquid metal glue thingie would do it rather than a weld job... does anyone know where this is located and if a normal jack job can get me there? i cant find it!

Hi Steve,

My exhaust was also resting on the reardriveshaft. I still haven't found what causes this interference. My solution to this was: undo the three bolts to the rearsilenser connection, and I tie-rapped it really tight on the rubber. Then I tightened the three bolts again. And as we say in dutch (translated) "child can do the laundry!" Piece of cake.

cheers,
Jeffry

whats the in £££ ? considering it myself!

[Mihnea]

I haven't tested them yet but I know for a fact that an exhaust is critical on turbo motors. This guy's turbo exhausts seem to be the same as NA ones, which means that if they have any performance increase over the stock NA exhaust, then it means that you'll lose performance with a turbo engine.

What you want with a turbo engine is as little backpressure as possible, and the exact contrary on a NA engine...

HTH,

Mihnea

Loosing to much back pressure can be detrimental to the oil seals of the turbo. You don't want a smoker :eek2:
