Doing only the exhaust no problem. When you change the air cleaner/intake,

thats when you should/have too, remap.

As long as you don't change the rate of air flow in. You can still do the

remap with the mufflers and improve temp and preformance.

I didn't either until I did, and the mufflers started to yellow. This is a tint of the chrome and does not clean off.
