haha yeah i agree, I love the way the rsr sounds though, its really deep and clean I just think I will get more performance from the HKS

 

mhmmm i guess.. either way its a nice exhaust, everyone gets it for a reason but either way its your G.. do what you want and make it how you want it.... hiiii haterss

 

I had RS-R before and went to Injen true dual SES.
THere is a performance difference but not a lot.
It's not a must since RS-R already gave a pretty nice gain.

Do the HFC or TP and you will see a pretty big difference.
I did HFC the last after i have all the bolt ons and SC.
At first when i got my HFC it took me a while to get used to the car because the performance difference. Even longer than I went from NA to FI.

So do the HFC or TP and you will see some nice gain.

 

you are forgetting about your Y-Pipe, unless you just failed to mention if you have one. if you are going to do HFC's...would recommend Crawford, then you may as well replace that OEM Y-Pipe and avoid paying for labor twice. the real bottle necks in the OEM system are the cats and Y-Pipe. your RS*R is light weight and should give you all the performance you need on an N/A car when teamed with headers, cats and a quality Y-Pipe...would recommend JIC. if I were you, this would be my next step.
