Its not a stang but it is a 4.6L!!!
What set of mufflers sound good with the MOD motor? I have been running a set of Magnaflow High-flow Cat pipes, stock 2 inch H-pipe and custom duals beyond that with NO mufflers for 3 years!!! It wasnt too loud and sounded great!!!
I recently swapped my NPI motor for a 2006 4.6L 2V PI motor. I installed a set of 2004 mustang GT Stock exhaust manifolds. A BBK 2.5 inch offroad X-pipe. And custom pipes after that. Once again I ditched the muffler idea but this system is SO loud....raspy....and poppy....that I drove the car home from the exhaust shop and parked it. Car also has no backpressure and has no getty-up.
Mod List:
2006 PI 4.6L 2Valve 33000 miles
2004 Marauder Airbox/2004 Police interceptor intake tube
75MM BBK Throttle Body
custom ported/polished upper intake
Typhoon intake manifold
24lb FRPP injectors
Hitech Stage 2 Camshafts
March Underdrive pulleys
2004 GT Exhaust manifolds
BBK offroad X-pipe
Custom 3200 RPM stall converter
Level 2 J-mod
3.55 FRPP RAR w/Trak-loc
What set of mufflers will sound good, quiet down the exhaust, and create enough backpressure to get my throttle back? Car ran better with open x-pipe than it does with full exhaust......HELP!!!
