Drifting
yup! im getting my headers in this week. i want that boost in performance so i went straight for the headers. sound can wait, i already love the sound on my car as it is. its a TL and i dont really want it to sound really loud and raspy. i want it to be subtle, yet fastttt

headers hands down!
unless you arent looking for power and want sound then i would go exhaust. the exhaust on the tl is pretty good at flow, and most aftremarket exhaust only give it 1-6 hp, where as the header can get up to 20-30hp gains depending on model and other mods

I was just curious where the number came from.

Even so, headers are probably the best bang for the buck mod you can do to our cars.

But by any means if you're looking for performance gains, definitely go with the headers.

I would do the COMPTECH headers... a friend of mine with the TypeS did that on his car, and it provided a pretty nice added kick upstairs while in vtec. That mod, as well as the pully provide gains that you will notice. While they are not exactly cheap, the saying applies here.... no such thing as a free horse... you gotta pay to play here, but boy do they provide some excellent gains on the butt dyno.
Sound was not much different after the header was installed, so the car sounds like a stock car, until he gets on it![Big Grin](https://acurazine.com/forums/images/smilies/biggrin.gif)
pm "ndawood", he'll tell you more about it.

headers WHP is correct, if installed on Type-S. However, no way an intake will give you 10whp, the crank pulley gives a Type-S around 12-13whp and cat-back exhaust on Type-S wont do much.. 5whp would be pretty damn good.. on a TL-P exhaust might do more though..
