MAC's E500940 Unequal Length Chrome Short Tube Headers have 15/8" Primary Tubes with 21/2" collectors. Made with 16 Gauge Steel with Single Port Flanges to prevent loosening that may occur with solid flanged headers.

All MAC Headers Retain Emission Controls (when needed) and come with Threaded Flanges, Machined Steel Studs and Locking Flange Nuts.
Chrome Plated, Uncoated (Raw) or Polished Ceramic Headers are made with Heavy Gauge Mandrel Bent Tubing!
The Original & Still the Best Exhaust! System will include Header Bolts, Studs & Nuts and MAC Header Gaskets.
