Custom "Spacer" exhaust.100% stock exhaust. I took the springs that are right before the muffler that connect the exhaust together and put them in between the two pipes then tightened it, Thus leaving about a 2" gap for the exhaust to escape instead of being muffled. I have had it like this now for 17k miles no issues, Nothing is burned underneath the chassis or anything. And it's just temporary.
