Customer Questions


Will this cause a lot of rasp when installed with a header? Would be keeping the stock cat back and would like a little sportier sound but not a lot of volume increase or drone.


This test pipe will not cause rasp in the exhaust tone, nor will it add drone. This is indifferent to the type of exhaust you have on the car.

Q:This test pipe connects to oem headers?
A:Yes! It is a bolt-in replacement.

    My cat needed replacement so I purchased this instead. Great fitment, well crafted. sensor transferred over no problem. Unhooked battery to reset. Check engine light never returned. Sounds great and slight increase in power a definite plus!

    Fit and finish was top notch. It does what it is suppose to do. The exhaust smell is not that bad compared to stock.

    Nice craftsmanhsip being put together. Smell is nothing too noticeable, sound stayed relatively the same, no CEL, and best of all, definite upgrade in performance. Can feel more power throughout the enitre rpm band and VTEC is MUCH MORE NOTICEABLE.

    Nice construction, however, can not get CEL to disappear even adding a spark plug defouler... This is a deal killer for me so unfortunately will have to sell online.

    Note from Heeltoe: There has been a recent improvement to these test pipes which further reduces the likelihood of a CEL. Also note, a CEL with this part, while annoying to look at, has no drivability penalty.
  • Fastline Performance TP 2.5 March, 2
    By Almostlude, Spirited/Stylish Commuter
    Very well constructed TP, very clean welds, exellent materials used, including fastners. Integrated defouler is very nicely constructed, for the price, it would be hard to find a comparable TP. I did have some CEL's but with the addition of another spark plug fouler was able to address the problem.
