DO you gain power whit the HKS or u loss power(that what i herd about tis exaust)

s2000vtecvtec

i have HKS dual exhaust with oem intake, cat, and headeron my AP2, but i won't dyno it.

However, someone did dyno his hks dual exhaust with test pipe, k&n fipk. he told me that his car only pushed 5whp less compared to another ap2 with skunk2 exhaust in the same day.

read his description.

^good video but not really a good example of how the HKS really sound. HKS sounds much nicer than that. Running it on rollers must be different than running it on the streets.

Here's my own version of it. Juuuust slightly better than the above.

ive had this setup on both of my s2000's. S~Factor's video gives you the best idea of the sound - love it. the drone on the highway is pretty minimal compared to the other exhausts i've owned, thats why i bought this setup again on my 2nd s2000.

My old setup.

Won't play in screen for some reason so have to click it.

HKS dual with test pipe and the rear black resonator is removed.

i have my dual hks turned into single along with a Invidia tp and im not digging the drone up on top. i mite do what S~Factor did to his (wrap up the entire exhaust) to hopefully get rid of the drone. i mite wait til i get the exhaust sized to a 3". the drone makes the S sound Civic-like. haha!
