Are there any aftermarket exhaust systems that will fit a 2007 zx4?
Ive looked at a lot of aftermarket exhaust companies websites and none of them even have the option for a 2007 ford focus exhaust. Will a 06 cat back fit on a 2007 or am I just SOL?
So just go to your local muffler shop buy a performance muffler & perf cat & have the bend-up some customm pipe(s). A single 3" pipe will flow more exhaust than duel 2" or 2 & 1/2".
