Following on from Benny's lead in getting these mufflers for his GTB: viewtopic.php?f=55&t=19427&start=0&hilit=mystery
Well i may have just bought a complete catback with mufflers from a 2012 WRX to throw on the 3RB when the Raptor extractors arrive!
MSR was saying that these catback systems are good for 220atw on his dyno b4 they hit the wall. he has a system he was thinking about putting on his outback. lol
Be interesting to see what the exhaust note will be like once its all on there, and what sort of power can be extracted while keeping it quiet.
