So, I decided to risk $250 and buy the OBX-R Exhaust "system".
WASTED $250 + $60 INSTALL = $310!!!
took the guy 3 hours to install it!!
looks ok, sounds a little louder than a stock muffler with the valve always open.
performance, eh! feels a little better during take off.
Anyways, not impressed at all. Contacted OBX-R, waiting for a reply.
Might try to remove the resonator and see if it gets louder...
