i have a high flow cat but i was wanting to replace it with a test pipe. not sure what kind to get and i didnt find much on them, i have a 88 t2, what kind of test pipe are you running and if you can post a link to it then it would be great

a test pipe is just a straight piece of exhaust tube, shouldn't be that hard to find them.

Muffler shop should be able to make one. Cheap.

i got a couple i can see about digging them out and throwing them on my ebay store, since it appears the supply has kinda dried up.

actually you might want to do as barkz suggested, the racing beat exhaust dimensions are kinda odd so a stock length test pipe may not work.

Any exhaust shop can put something together in a few minutes. But for the "pipe", use a quality resonator instead. Your ears, and everyone around, will thank you. Plus it takes all the angry bees out of the exhaust.

well the turbo cars don't have such a buzz, the turbo muffles alot of that sound but i'm not sure what real benefit there would be in replacing it with a straight pipe aside from maybe a couple HPs which you will barely notice.

This is all I found on one, I already have a downpipe but don't have the test pipe, would this one In the link fit where the pre silencer in the pic above is at? It doesn't look long enough http://pages.ebay.com/link/?nav=item.view&alt=web&id=171404865669&globalID=EB AY-US

like i said, Racing Beat's exhaust dimensions are a bit odd so no, it won't fit. you'll need to have one custom made by a local exhaust shop or order one custom made with the dimensions you need.

I missed the fact it was a turbo. Oops. Turbos indeed make the fastest mufflers. Though, considering that, does it mean that there are now muffler bearings?!

i had a muffler bearing.. had to cut the exhaust at the y pipe to get it out...

true story

it goes like.. i wanted to control boost creep, i wanted to run 10-12 psi but it would always creep to 17ish( N/a rotors.. high flow bolt ons) so i put a timing belt pulley in the exhuast to make a restriction. orignally i had it in the downpipe and in front of the gasket, and it was bigger then the gasket hole so i thought it would keep it in the downpipe so i could remove it after testing.. well the tremendous boost pushed the ****** pass the gasket all the way to the Y pipe and there it was stuck.. for 2 years... the car returned to stock power levels and would make about 5 psi max.. very horrible spool.
