Camaro5690 Posted February 15, 2011 Share Posted February 15, 2011 Anyone on here make or know of a dual exhaust? I was thinking if you cut the Y out of the manifold and ran two pipes with some sort of crossover in the system. It couldnt be too large, maybe 2-2.25 inch pipe. Might sound a bit different than the usual single pipe. Link to comment Share on other sites More sharing options...
Ionlyhave3suubs Posted February 15, 2011 Share Posted February 15, 2011 Looking for sound or performance? A different sound you may get, Better performance, probably not without significant and matching engine modifications. Subaru exhaust systems are pretty efficient from the factory. If you are just looking for a new sound, I would consider a muffler change, perhaps a performance muffler with single inlet and dual outlet. Although I have never personally experienced it, I have had friends who have added dual exhaust to their cars looking for a performance increase and ended up losing low RPM torque due to a loss of back-pressure. This experience has been with non-Subaru vehicles though. Maybe someone else has specific to subaru data. Link to comment Share on other sites More sharing options...
MilesFox Posted February 16, 2011 Share Posted February 16, 2011 do it in an x pattern with 1-3/4 pipe and shorty glasspacks right off the x Link to comment Share on other sites More sharing options...
subaru360 Posted February 16, 2011 Share Posted February 16, 2011 It will be loud and slower. Waste of money. Link to comment Share on other sites More sharing options...
