I have a 04 F-150 Heritage with a V-6. When I look on Magnaflow's website, it does not list any trucks with a 4.2L V-6. If I buy a systems for a 4.6L or 5.4L truck will it work on my truck.
thanks

If your stock exhaust piping is 2.5 inches after the Y pipe then it will. I can't see there being a huge difference between the 4.2 and 4.6 exhaust.

 

how does ur imco 3" extreme sound??

 

FasterF150, it's the most badass sounding exhaust I've ever heard. Extremely loud and deep, but still very smooth. It blows my neighbor's Ram Hemi out of the water, and he has true duals. I bet he'll be picking up some IMCOs soon.

 

I am trying to find a place on the internet that sells IMCO, but can't I know ebay has them but not in 2.5 in and 2.5 out. Any help???????
