The biggest advantage to a catless system is the immediate relief from the engine bay heat that destroys all the plastic tubes and vent lines that cross over the engine. Cattless downpipes also provide a unique sound that is a bit louder and more "M" sounding. I was considering doing the exhaust mod or going with an aftermarket exhaust, but once I installed downpipes, I really didn't feel the need to upgrade the exhaust other than adding 3.5" Dimisa tips.... Most think that it is a performance exhaust because of the sound and the tips.

There may also be a small performance upgrade, but I couldn't really feel any difference other than the sound.
