exhaust problem
i cut the cats off my 2001 5.4 and i have a magnaflow single exhaust i like it in idle but one you rev it up it has a clicking sound. would some long tube headers make it better or worse?
yes, put some high flows on and Im sure it will be better.
hey motard, you know what the rules are on cats? just gotta have 2 right? this one shop said it would be fully illegal to even touch them...
