I was just wondering if anybody has taken off their exhaust leaving the rest of the piping on.

There was a guy in columbus that told me to try it and see how it sounds

is there anything wrong with doing that?

i was meaning like just taking off the muffler itself and then leaving the rest of the piping

 

Not really but why do it? Just get a 3" turbo back system with test pipe and you'll have increased power and the strong sounding exhaust you want. Defenitely worth the money. I got one.

BTW - I am also in Columbus.

 

the guy i talked to was quantum evo

There are different places you can split the exhaust too. You could seperate it from the down pipe and run with no cat, or just remove the muffler. It's gonna be loud no doubt and it's gonna look odd with no pipe out the rear. If a cop hears that and then sees no muffler or pipe out the rear yer best bet is yer gonna get pulled. Running no cat is a big no no.

 

stvbreal,

Running a 3" turbo back means that you either need to upgrade your stock cat to 3", or use a 3" test pipe instead. Of course, some people opt for a 2.5" downpipe (still bigger than the 2" stock downpipe), to compliment the stock catalytic converter which is 2.5" as well. But my major point is .... having a 3" downpipe, 2.5" stock cat, and 3" cat-back exhaust makes no sense at all since the smaller diam. cat will restrict flow.

 

thats my exact set up. 3inch dp 2.5inch cat and 3 inch cat back..... I really want to put on my test pipe but i am scared of getting caught.. and not knowing the penatly

 

Wayne ... I think either UltRacing or RMR make a 3" high flo cat if you don't want to take a chance with the test pipe.

 

The RMR 3" high flo wasn't ready last time I checked (last week). Apparently, the RMR cat is smog legal (i.e sniffer), but violates some code preventing a cat replacement in the first 5 years of the vehicle barring theft (really officer, they stole my cat...), or some sort of catastrophic failure or damage requiring a complete replacement.

Reheat has got it right. That is the way to go for sure. How much did that cost btw? Couldn't be much. I think every one should at least hear what a turbo car sounds like without a muffler. The stock turbo absorbs most of the noise anyway. Anyway aren't most catbacks for turbo cars a straight muffler?

k_fabec: The thread said it was like $60 bucks for the setup, and the 3" pipe was welded in after the 1st resonator. I think most aftermarket catbacks have straight-through mufflers, yeah.
