Im running CC b290-6. Dougs 1-3/4 headers. Mufflers are by Car Chemistry.
They are 13'' long,3'' dia straight thru type mufflers.They are bolted directly to the collectors.No exhaust from there back.

They also make an insert that slides into the collector. It is just a tad quieter than open headers.

Eventually i will run the exhaust all the way back so i can use the factory 65 splitters.
