I think I messed up
I know this is a super old thread but how did the magnapacks turn out with stock cats. I have an 04 with the 4 cat setup. 5.4 magnaflow 14" oval body followed by what I think are bullets but I'm not sure. Wanting to know if cutting the rear cats off and going with the 4x14 cats will be too much.
Yes it wouldn't be as loud as mine, but not far off. My bud's '04 FX4 has a Cherrybomb Extreme exiting lightning style on his 4 cat system, and my truck is very much louder. Hack out those rear converters and it will be much better.
