Just got my '13 DGM 5Dr. Love it but, as most, want to do some modding. I'm not super keen on particularly loud exhaust but also don't want to have to do swaps for emissions testing. Do the SPT exhaust systems cause any emissions issues? Visual inspections? It IS a bit on the louder side to me but if I can avoid emissions complications, I would make that sacrifice.
Also, I've seen a bit about warranty issues when making power upgrades. I'd assume as the SPT is a Subaru part, there are no warranty concerns. Is this assumption correct?
