On my BDR sidepipes, the muffler was way to restrictive, looking for a more freer exhaust, I ordered some tubes from DR GAS. They are 3.5 inches in dia with a 90 on exit end. They even cut the 90 end to match the exit end of original sidepipe. Had them swedge other end to slide over existing end of pipe after 4 into 1 union. Bought some Vortech cones from summit, welded them in just a little past collector, also put in one of the little insert mufflers we use to run on our IMCA dirt cars, wallah!! now have free flowing exhaust with a very authoratative sound. The pipes then got ceramic coated looks real good being a straight smooth tube with no buldge for muffler showing.
