Hey, on my 1994 9000 Aero Turbo i have a loud noise coming from the exhaust like
theres a hole in it. But it's not the muffler, it is this mesh thing in about mid-distance between the axels.

Here are some pictures or if sort of peeling at the top.
I'm just wondering what it is called.
It is only a 2 or 3 feet piece.

Thanks.

Okay it's an Intermediate Pipe, im going to look in the pick your part,
if not i found one on at autopartsway.ca for $175

Does anybody know what it does?

in america its commonly known as a flex pipe. muffler shop fix for around 60 bucks

Is there anyway i could just straight pipe it?
or is the flexibility a neccessity...

And just wondering, will the muffler shop just weld it back shut?

if you dont use a flex pipe you will start loosing/breaking exhaust parts,like your manifold bolts can sheer off, and parts will break and fall off. take a trip around the block with your hood off and you will see why there needs to bex a flex bit, the motor moves back and forth quite a bit during shifts and acceleration. it looks to me like your flex pipe is where the convertor should be, the flex needs to be closer to the downpipe to work correctly. the muffler shop will want to replace it completely. you can diy with muffler clamps 2,1/2"id, straight pipe prolly about 4ft,flex pipe, a sawzall and a **** load of patience. everything but the sawzall can be bought from jegs,summit,or even ebay. just be sure you bolt everything down as tight as possible.

that's great information, thanks.

back to the question about the muffler shop...
what would they do to fix it? just weld it back shut?

i would imagine the muffler shop would want to replace it.

reidg

so like you said, you'd imagine it should be closer to the down pipe for it to work properly... if i were to replace it with a new one, do you think that it'd just keep ruining the way it has?

the mesh is the flex pipe
