I would argue the fact that the Corsa's are the best sounding exhaust, I have to say the FRPP are. But you can go to Tommy Vaughn and get the FRPP kit (they are off I-10 near Washington) they had mine in stock, it was $580 for the whole kit.

If you ever come to Kemah when we are there you can hear how mine sound.

 

love my JBA's. if i had to go a different route, i think i would try borla (FRPP). Here's what my setup sounds like:

*ALSO, keep note that i recorded this on a cold start. that crackling you hear in the high rpm's fades away once everything gets warmed up and is barely there when they finally break in. this recording was about a week after i first had the setup installed 2 1/2 yrs ago. good luck with whatever you choose.

 

i went with the jba hpipe and gt takeoffs and i love it! low growl but not too loud no drone.. perfecto!
