if you go from an hks duel that people lose power from and a greddy tic single your looking aroud 10-12whp

 

since when does an exhaust give the s2k 10-12 whp.....

 

do some reseach, tell me how my ap1 with fipk and 70mm test pipe and single exhaust put down 231 whp and 159 tq?? i know the dyno reads high but come on its not reading 40 wheel over.

 

 

I have an Asura 3inch hi flow cat and Asura 3 inch dual and made 394whp at 10.5 psi. Sounds amazing and no drone with the 3 inch cat. This dual makes powa!

 

yea wit intake and test pipe. you made it sound like exhaust gives you all that. now if you include the others one then yes i will believe that...

 

we need a post with the gains on different exhausts dual and single ...powergains on the exhaust alone...

 

Like the looks of dual but will go single because of turbo.
As I posted in another thread, we compared dual vs single (both 3") on a 400whp Focus, 17whp up on the single. Well worth it and lower weight.

 

i gained alot from those mods. my butt dyno went up alot as well as racing people before and after. im not stating its all in the exhaust but i would say half of that. i would say catback/testpipe, worst case 10 whp on my car.

standard ap1 dynos 190-200whp and 200whp be AT best. some cars are freaks and will put out a little more. i know the dyno i was on reads about 10whp high on s2ks. i bet i gained 20-25whp with those 3 mods.

 

This is clean man!
