Thanks bro!

It's a full custom system that runs from the cats. The system (in a way) mimics the fast intentions setup until it gets to the mufflers. There are two single inlet, dual outlet mufflers. Each outlet has it's own pipe where the tips are connected.

The stock diffuser does have to be cut. My diffuser is cut slightly higher than the usual install jobs because I didn't want to leave the round bevel on just 2 out of the 4 tips.

These pics will further explain
