[Nismo_line]

thanks

I went from a slowly 290whp to a whopping 425whp with a test pipe

Forget the test pipe. What minor gains you'll have does not compare to the damage you cause for the environment, seriously. You can make better power elsewhere while staying clean. Get a high flow cat is you're strapped for cash and need to resort to that component to make power. At best, a delete pipe can make 10whp and a bit faster spool.

I didnt get a chance to dyno my car before I installed my test pipe but I have tomei dump pipes,3" Apexi titanium exhaust ext (with test pipe) and a small Apexi muffler and before the test pipe i\t sounded great,after the test pipe it sounds really f**#ing awesome !!!! It will be loud but not to loud - do it.

There goes your carbon foot print. Seriously. When the new emission laws pass ( noise and environment), you're gonna see the light. It's coming, Canada wide.

meanwhile, super tankers burning bunker fuel continue to produce massive amounts of pollution. Going after cars is a feel good move at best.

Ah well. I do my part for the environment. Every little bit helps :S

My car came with a test pipe (take it it gets rid of the cat?), sounds great, and passed inspection.... Im in sk though, so we dont have any of this emissions stuff.

some scientists say that we have already past the point of no return. Anyways when I put a straight pipe on my car I couldnt really tell a difference perfoance wise but it sure got louder.

Truth is, one more person without a cat is not going to kill the earth....

Thats like people that buy electric vehicles because they want to be friendly to the earth, "oh i just plug it in and it drives!!", what they dont think about is the huge factory pumping out tons and tons of smoke to charge their car...

what is a way to not have my check engine light come on

[Skym]

Clamp cat overheat sensor to side of exhaust with intake hose clamp to earth it.

I have a screamer pipe, to blitz dowpipe, to decat (test pipe), to full 4 hks resonated mid and catback. Really nice deep tone and not too loud. I havent had any problems with my check engine light coming on, but I left my cat overheat sensor off so thats the only light that shows up.

Your hks exhaust system sounded a bit louder then mine in person, so with a downpipe and test pipe your car may be quite a bit louder. I think it will also run a bit richer too.
