Ok guys, I have a noob exhaust question. This weekend I bolted up my LT's/ORY and running it through my open cutout, right past the connection of the ORY to the stock pipe. I love the sound and it really screams up-top, but long story short I miss my torque. I think I've decided on the Borla XR-1 Sportsman muffler. My concern is that the flow-through design won't produce enough backpressure to (re)build up my lowend, and I'll be right back at square one: no power until high RPM's. I know Dodges are noone's cup of tea around here but I'd appreciate any input from the gurus. Thanks guys
