Okay i have an 02 t/a ws6 with factory manifolds and magnaflow cat-backs. There is an excessive build up of carbon on the left side tips but not on the right side. I can't figure out for the life of me what is causing it. Any helpl would be greatly appreciated.

Normal, this is just how cat-backs are for our car. The only fix is a dual system.

Yep. Exhaust takes the path of least resistance like anything else. It comes in from the right and out on the left and right. More exhaust will always flow out the left side because it has to make a complete u turn to exit the right side. Basically the right side only flows out what the left side cannot.
