4to1 2in 3out

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 CNC billet turbo collector features slip-over entry pipes to make welding and fitment easy. This ready-to-weld part cuts hours or days off your exhaust manifold build time, and gives you a much better exhaust manifold!

Made from 304 stainless steel.

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