Hey guys, after a fair amount of research I'm pulling the trigger on a pair of Doug Thorley Tri-Y's, ORY and no cats for my NNBS. I know a lot of people on this forum run the Pacesetter's, but I want to give the Doug Thorley's a shot. I currently have a Flowmaster 40 Series and turndowns after the muffler. I'm sure the 40 series will be too much after the Tri-Y's and ORY, so I am changing mufflers. I am tossed between a 3inch inlet Borla Pro-XS (no resonator or bullet) and a 3 inch inlet Borla XR-1 with a 12" Dynomax Bullet in front to cut out rasp. Which set up should I get? I'm really not sure what to decide. Input would be great.
