would you guys sugest running a highflow cat or a test pipe with a tbe. thanks alot

 

testpipe

 

test pipe=more power but more noise, and cannot pass emissions

hfc=less noise, less power but still good power, and emissions friendly in most states

 

Searching would offer more answers and opinions.

 

test pipes are very nice, very but the tickets you can get and the sadness of not passing emisions isnt worht it, i still run a test pipe but i am getin a perrin cat because ima get the qtp evo downpipe that has the electric cut out made with it so when i wanna run no cat a can with a press of a button and still pass emissions and if ya wanted to you could run the stock exhaust and gain about 33 hp

 

I say stock cat.

 

race track = test pipe
daily driver = HFC or stock cat

 

I personally have the Perrin exhaust with the downpipe and I run a testpipe on my car. I have ran the testpipe on my car every since I have had the exhaust and it sounds good. However, Im lucky because my dad owns a shop well him and his freind and they inspect my car so I can avoid the headache and the windown tint does not make it any better when it comes to inspection.

 

it depends on your emissions in your state. its a ***** to go back and fourth, but if you do it correct with the "black box" on your test pipe it fools the cpu saying everything is legit. but if you want power and loud *** sound gofor the TP. High Flow cat if you want sound and not the hassle.
