As you know the factory exhaust system is pretty restrictive..I mean my bros. 5.0 'stang comes stock with 2 x 2 1/4" pipes But my 6.0 exits into one 2 1/2" to the muffler where it exits at 2". I just sort of remidied some of the dilemna today. My buddy has a 4100 which the previous owned killed the exhaust after the cat, it sounds pretty mean. I did almost the same but just removed the muffler back.. It sounds realllly mean, a bit too much. But it's breathing much better now. This isn't my final solution. I'm planning on having the entire exhaust redone, the Y pipe off the headers is cracking anyway. I want dual exhaust but I want to exit in front of the wheels so the tips wont scape. My question is what would be my best option (mufflers, pipe diameter, etc) for power and a nice sounding rumble?
Thanks for the input.
