5.0

Red370

Magnaflow muffler deletes... less than $300, Pypes also makes a set for less than $250 on americanmuscle. Cold start will wake the neighbors, tame at idle (you can turn the idle up with the SCT tuner), melts faces at full throttle. BTW, get the tune man, the TQ gain down low and the mid to high range hp are ludicrous. According to Chris Young at AM, the JLT/Airrade provide the biggest gains of all the CAI's. I was at my current HP level with just the intake/h-pipe, decided not to go with an x because they are MEGA raspy, moreso than my Stillen/Berk combo on my Z.

I don't wanna wake up my neighbors though.

Yep, if you live in a nice apartment complex you will be kindly asked to move out by management.

There's a douche at my GF's complex that we have been calling the complex about because he's running pretty much open exhaust on his 5.0 and likes to rev as he drives into the complex late at night. Sorry dude, but that sh*t doesn't fly around here. (It does sound good though!)

I say get the GT500 mufflers. If you want it louder, have your resonators removed.

My FRPP Sports are as loud as I'd ever want to go on a DD.
