LT Exhaust Flanges

This is a PAIR of 1/2" 304 Stainless Billet LT exhaust flanges, Offered in 4 primary tube diameters. The I.D. of the ports are smooth to allow the tube to protrude all the way thru the flange. These are surfaced on all sides out of the box. However, it is recommended to have them surfaced again AFTER welding to ensure full contact on the sealing surface.
