I have an ITR swapped 99 gsr. and lately ive been blowing alot of smoke. i contribute that mostly to having no cat. a friend of mine told me that you can run a catch can setup of some kind and it should get rid of that problem. its pissing me off because im turning my bumper black.

you guys have any input on this?

 

Catch can won't fix the problem unless the smoke is blue, then maybe.

What color is the smoke?

 

black.
