alright so i am pretty much ready (money wise) to go out and by my 40 series muffler and some mandrel bent tubing. i have been told in this forum that i would need to create a dummy pipe in order to put the 40 series in the place of my 80 series and retain my "dual" exhaust. does anyone know where i can get a 90 degree (curved, not right angle) mandrel bent tube that has the cut out so i can weld my exhaust tip to it creating the "dummy pipe" which will not come from the muffler but straight from the piping?

or another option if it works, would i be able to cut into the pipe that goes into the muffler and weld on the exhaust tip there?
