wow! guess I'm staying this way untill the gt takeoffs arrive....nice free mod

kinda reminds me of the 5.0 days...where the power was there, you just had to remove things from the engine to let it out lol

Are these 10rwhp muffler gains on a BONE STOCK v6 or are you testing them with the intake and tune on them as well?
