- 304 Stainless Steel
- 1/2" Thick Flange
- Thru-Holes for 10mm Hardware
- Smooth Internal Transition
- 3" Inlet Counter Bore
Our T4 flanges are CNC machined from 304 stainless steel. They're 1/2" thick and have machined thru-holes for 10mm hardware. The internal machined transition helps reduce turbulence and improve exhaust flow. There is a machined counter bore to accept and align 3" inlet tubing.
