straight pipes!
You wont loose horsepower, but your peak torque will move higher in the revs due to the back pressure difference. it will feel like a dog from a stop unless your WOT. Im probably going to start another back pressure war, but ive had first hand experience with it and thats what happens when you open it up to much.
I was running pacesetter LT's, ORY and SLP loudmouth. It lasted as long as it took for summit to ship a muffler. I hated it, but it was fun to see people jump when i started it.
