Out of the following which is louder and meaner sounding.

Tanabe R Medalion
HKS Hiper
A'pexi N1
RSR GT-2

 

hmmm im gonna take a stab and say apexi N1 ....but u have to take inconsider do u have headers? highflow cats or test pipes?? a lot is goin to affect the sound....

 

just the catback exhaust no extras. Also this is the tanabe hyper. Lets throw in the dnx exhaust as well.

I was thinking about the rsr gt ii.

 

RSR is probably the loudest, not so sure about how mean though. Look around there are tons of sound clips to listen to. You might think something sounds loud and mean and someone else might say it sounds like ****.
