2.5" compression bend or 2.25" mandrel bend
I will be looking at a header back exhaust system for my 77 stingray soon, however, I haven't been able to find a system in 2.5 in that is mandrel bent. The only mandrel system I find is 2.25 in. Which one would flow more: 2.5 bent or 2.25 mandrel? The engine I am building is an L31 vortec with LT4 hot cam.

Stainless Works makes excellent stainless headers and 2.5 inch mandrel bent exhaust system. I have the entire system, they sound great and the quality is top notch. They are expensive.

The 2.5" Pypes system is very affordable, a few years ago I paid $400 without mufflers but with an X-pipe. The fit was bad, it hung way too low. I knew about that before I bought it and did a few cuts and welded it back up (MIG with stainless wire). In the end I got a perfectly fitting exhaust for cheap so I'm happy.
