Long Tube Headers vs HFC vs Test Pipes vs Art Pipes

NickD · 06-29-2012, 02:56 PM

Thanks for the info! My biggest concern is having a back bumper with burnt/soot spots on it which is why i'm reluctant to get TPs. What option do you recommend for that? Will long tube headers be an issue (i'm guessing yes since exhaust fumes wont be processed)

I've had LTH's and CBE on my nismo for a few months now and NO soot or discoloration on the rear. The soot factor is more dependent on the engine tune (rich vs. lean).

Agreed but doesn't the elimination of CATs (w/out tune) cause the car to run rich or lean? I mean I guess if I tune it the same time as getting rid of CATs I should be okay.

It will lean it out a little bit (lean = less soot). The ECU will try and maintain the ideal fuel to air mix within limits. When I ordered my LTH and CBE I talked to Tony at F.I. and was told that until I go with a CAI I wouldn't need to worry about getting a tune.

The real draw back to any of the options you listed, especially test pipes and LTH's, is that the car is no longer street legal in terms of emissions. That's not to say that there aren't a lot of us running one of the options listed but technically we're all just hoping not to get caught.

Do you pass inspection?
