Okay, I need a little help on deciding what's best to do. My objective is to get top performance with 75% sound of the loudest exhaust available on the market (which I believe is X02?).

Option #1:

Injen CAI, (Insert Exhaust Headers Here), Berk Technology TP, Greddy SE Cat-back

Option #2:

Injen CAI, (Insert Exhaust Headers Here), Berk Technology High Flow Cats, TurboXS Cat-back (with M-Pipe)

Option #3:

Injen CAI, (Insert Exhaust Headers Here), TurboXS TP, TurboXS Cat-back (with M-Pipe)

and how is the Fujita CAI for the HR?

 

hks exhaust with berk high flow cats and crawford headers

 

^^ crawford doesnt make headers for the HR. Turbo XS TP's only fit DE's. Does anyone read posts before they post? OP theres a VQ35HR section, try using it.

 

injen cai-stillen headers-berk hfc-hks hi power

 

Does anybody CONFIRM posts before they post? Try doing it.

injen cai, stillen headers, stillen hfc, bassani exhaust

 

^ skip on the stillen headers, not worth the money or time for the minimal gains they create.

 

+1

 

With the money you save on the headers , go for a technosquare reflash or cobb access port.

 

10 whp in midrange is not really minimal, but i guess if ur not doin it urself it can get pretty pricey

 

why x02? hks,berks hfcs,injen cai will be my choice then retune....which i still need to get....

 

Uhm, why would you want the loudest exhaust available?

 

x02 is not the loudest exhuast out there either. idk where you got that info from.

 

Because its the same exhaust for a quarter of the price.

 

i hope the OP realize that unless he gets a tune, those mods are useless and won't give him much except a loud sound..

 

sorry bro..i own a XO2 and my buddy owns a HKS...

Not the same.

xo2 has thinner pipping and with HIGH flow cats u'll get an annoying ringing sound...check my post and look at the older vid on post #4 i think...


LOUDEST Would be a Single Exhaust

 

+1 unless your going FI, then I would suspect there are gains to be had with aftermarket headers.

Check out the Bassani exhuast if you haven't made up your mind. Just had the true duals installed 2 days ago, great sound, not loud in the cabin cruising, no rasp and great gains 10+hp by just tacking on the exhaust on a stock HR. Added bonus, the gf says she gets excited by the deep sound of it!

If your worried about being too loud, I would toss out the idea of HFC's, just my 2cents. You'll have quite a bit more sound and a bit of rasp with HFC's of any brand.

 

Hmmm..... cat back with test pipes??? I.m.o thats too much.... I have a Turbo XS Cat-back on my HR and i love the way it sounds but its preaty loud..... and thats on stock cats. If your going TP be ready for alot of rasp added to the sound, something you dont get from the regular Turbo XS combo w.o TP

 

+1
