I'm looking for some mandrel-bent pipes to go over the rear axle, either 2.25 or 2.5 inch, for my '71 LeSabre (soon to have 455). Nobody within 200 miles of here has a machine, will the tailpipes from an A-body work? also, some 3-inch curved headpipes pipes to connect to a set of TA shorty headers. I'm looking for some to go back about 24 -36 inches, into a set of flowmasters. Then I'm going down to smaller pipes over the axle, and a set of Dynomax's at the rear. Should give me a zero-loss system that's really quiet. Whee!
