You didn't mention the type of car that you have, but im going to assume base or sport 370z.
Intakes yield good gains. K&N dropins + MAF Tubes = 16whp compared to Stillen g3s 18whp
QUIETER EXHAUSTS with gains:
Fast Intentions 18" Resonator
Stilen Catback
CNT Catback
Nismo Exhaust
Do some searching on here buddy...

Mine is a new 2013 370Z with sport package. Thanks for the info!
Anyone have a recommended combo of intake and exhaust that work well together, create some power/throttle-response gains, and don't create a ton of noise? I want throaty/beefy exhaust just not like some you hear that are obnoxiously loud.
