which one is the best?? and how much would it cost? i have CAI and N1 - would it be best to do the header before the cat? thanks

 

straight pipe...what...only prob. is the CEL....

 

Go to North Tampa Custom....he will hook you up with a hi-flow cat...and will do a good job....i got one(cant remember the brand-but was well known brand)and he did a little custom job for me and my car sounds great ..nice deeep tone. they are over on Nebraska ave.

 

try testpipes.com. this is where i got my testpipe and its pretty nice...fit perfectly..etc..and the guy i talked to when ordering said they can include a place for the o2 sensor...if the car is obd2. not sure about check engine lights in that case...as i've never had an obd2 car...

also, high flow cats in my opinion are a gimic. if you're really worried about damaging .0000001% of the atmosphere and absolutely need one just get anything thats 2.25 inches in diameter. the difference in restriction and horsepower gains will be very small and probably not noticeable.

just don't spend 160 for a cat...its such a waste of money.

 

he could covert to obd1 to lose the code which is what you need to do insted of running that gay force ecu
