3.0 + headers + ?
 

Hey guys, was digging through my parts boxes the other night, came across the set of headers I had scored for the 3.0, had forgotten about them. I had already purchased a dynomax muffler to install on the stock exhaust on the car already to make a 1 in 2 out. It won't work with the headers. So what would be the recommended dynomax for a 2 in 2 out setup, or is there a better option?

Background, the car is used mainly on the track for DE's with an occasional drive around town.
