I used to have a twin exit exhaust and used to get the dreded smoke on idle after 10 mins, i have since got a single exit (like the sound) and the smoke has disappered. This maybe a silly question but i would like to go for the 2 fast 2 cool de cat setup as one of my cats is rattling around. Am i right in thinking that the smoke would come back to to the lack of back pressure with no cats.
