I'm thinking of having FRPP shorty headers installed on my 07 GT. I would like to hear anyone's experience about how this sounds from inside the cabin of the car. I at one time had Magnaflow's x-pipe with high flow cats and the in-cabin noise was too loud. I am now back to the stock h-pipe with steeda axle back exhaust.

I had shorty's... at one point, but they were JBA... they didnt really make the car louder. they just changed the tone of the exhaust. I had a magnaflow catback system on also. It just made the sound a little deeper instead of louder... thats my experience with JBA though. Ive heard FRPP shorty's in person with a catback, and it seemed like thats all they did too... (just changed the tone)

Tone change with no volume difference

I would say you're better off with the JBA shorties since they are tuned (equal length tubes) or even the BBK. You should see a better power increase from those two over the FRPP since it's not tuned.

I'm thinking of going JBA shorty myself. But who knows, I flip flop constantly on this issue.

Does anybody know the part number of the highflow cats that come on the magnaflow x?

search it on their site? im pretty sure they sell just individual cats on their site... if not, my bad...
