Thinking of removing the multi-chamber rear Borla muffler and replacing it with a straight 3" stainless pipe (the one behind the rear axle) and then have a pair of Borla race mufflers welded into each side of my ORY ... tired of the rasp at low rpm. I believe this will totally eliminate it.

What do you think about Borla XR1 mufflers for straight-thru flow and least loss of power on each side of the Y-pipe? It should allow exhaust gasses to flow out both rear exhaust pipes ... instead of pushing it all out one side through the muffler. What do you think?
