4to1 1.5"sch10 in 3" vband out


Very popular with the Promod drag racers. Holds up much better than welded collectors, that reportedly fail continuously in heavy drag racing use.

Comes with matching vband(for 3" OD tubing) and clamp! Featuring angled inlets to allow you to easily weld around all 4 pipes.

The ultimate part for making exhaust manifolds for maximum performance. Featuring smooth transitions, and exact dimensions for the best flow possible. This translates into less back pressure, and means more power with the same boost, or the same power with lower boost (and less lag)!

This ready-to-weld part cuts hours or days off your exhaust manifold build time, and gives you a much better exhaust manifold!

This is the best CNC merge collector available on the market. CNC machined from a solid billet for maximum durability.
