okay i know what a straight pipe is. makes a wierd rattling noise when you rev your motor and ish like that. does the test pipe do that? does it make any annoying sound to it? is it loud? would it increase performance if i just put it on with my stock Muffler and piping?

 

hah..no that's not the reason behind a test pipe. Well for some it is, but the real reason behind a test pipe is that ite has no restrictions inside of it like a catalytic converter does. So, it's free flowing device for your car. It will release some pent up power....different cars vary though, so you'll have to go dyno and see the results. Also, you can also get a resonated str8 pipe which will tone down that 'ricey' pingy sound you get with an unresonated test pipe.

Of course in some states its way illegal to run a str8 pipe/remove the catalytic converter for street use. But, if you're the type of person that doesn't care then disregard what I just mentioned.

 

I noticed that you're in CA. If you get caught it's a $2500 fine. But it's supposed to be more free flowing and you should net a couple of extra hp from it.

 

the fine is a grip and I've seen it a happen a few times in socal.

 

i know its not the whole point of making that annoying sound. but my question was does it increase like hp or anything. do you guys really think its worth it? i wanna get one...i own a 2000 si and want to increase some torque. maybe some hp how do i do it without making it all loud... how loud is that ricey noise?

mine is resonated. im going to put it on this weekend with my new header

 

I thought a test pipe, and straight pipe was same thing, oh well....just get a dummy cat.

 

they are

 

My testpipe made my exhaust so stinky, it would almost make me dizzy when I stopped at a light and sat there. Not to mention the ear bleeding noise my tanabe made with it on.

 

Given that I'm close enough to breathe your exhaust, I'd have to say no. Or did you buy your own personal planet?

 

nasty fines. I just got an extra cat and banged it all out so if you look under the car you see a cat but it has nothing in it. Pesky coppers
