Just installed the Invidia Gemini on my G37S and it sounds quite nice, but it's not as loud as I want it. That being said, I've been looking to buy HFC/RHFC/TP to pair with it but I can't find much info on cats/tp with the Gemini. Anybody running the Gemini with some form of cats/tp and can vouch for it? I'm looking for a clean sound (no rasp) but I do want it louder than it's current state.

Thanks!

 

I have it and love it, installed Z1 non-resonated pipes and it really woke it up. Not crazy loud but sounds good. I have no rasp. I do get cel light about once a month. I think Invidia did a great job for those not looking to wake up the dead lol

 

 

FI resonated test pipes. Zero rasp or hiss.

 

ART pipes sound great with the Invidia's. Deep sound, no rasp, no drone on the highway.

 

I have the Gemini paired with Berk HFC. When I was looking for exhaust, I mainly wanted the deep tone sound and not overly loud but still hear the vq sound engine.

Super quiet on idle but roars tamely when you punch the throttle. Makes Flat foot shifting more enjoyable!
