I need to find 3.5" tubing and mandrel bends in the same size. Any help is appreciated.

Jegs or Summit has up to 3". That ought to be plenty big enough for a pretty stout motor. Gonna be tough to fit anything bigger under there.

3 inch is perfectly acceptable for a Small Block based motor, but NOT an 8500 RPM Big Block. The plan is for 3.5 inch headpipes, merge collector, then 4'' back. It's more of a weekend cruiser, not an all out race car, but the power(800+) is on tap, in case the need arises, so I figure the Mufflex is acceptable in this case.
