there are other options than FI. i agree many components are the same but some are different. i would like to think the bends are what would make the power or lose it. IF you want hks just wait it out or go with the one that comes out for our car.

the people running G35 tein springs cars are slammed and i know the spring rates are not correct. the teins that come out for us will be much much stiffer.
but again its your car and you have to do what amakes you happy.

Stillen, impul Fast intentions are the ones i know. Injen to is coming out etc

Just be patient if nothing suits you now. i know my boy is project is selling a stillen exhaust. go for that one or the impul one or just wait it out if FI does not fancy you. just be careful imo. until things are dynoed who knows back to back.

 

i wonder if g35 amuse powerhouse would fit, id through that on my car if so before any g37 exhaust out such as stillen fi mosts likely hks n injen..

but ima hold off before i make any moves bc injen n hks might have something up there sleeve... if not ima go with a top name brand g35 exhaust n save a couple bucks
