Hey Guys Im Wally I have a 2010 G37 coupe I have stillen Cat back but now want to get some more power and have the sound a bit lounder,

So need your advise which would be better to install first Intake or Test pipe and if you guys recomend something that will be great.

Thanks,

Wally

 

It doesnt really matter which one you do first..How about also adding a full catback exhaust

 

I already have a full catback stillen,

Did you add TPs on your car?

If you did, did notice the power differance?

 

^no I do not have TP

 

You should get the intakes imo, then the test pipes, or hfc. then a tune

 

i think you will feel more power with test pipes over intakes. not sure though from experience but what ive read is the cats are the biggest choke point of the car. do a little research and i think most will say you will feel most gains from test pipes over intakes. get ART pipes!
