4 into 1 Round Turbo Merge Collector with 1-1/4" Tube Size, V-Band Fla

All fabricators know that more often than not the most time-consuming aspect of fabricating a turbo manifold is making the merge collector! The Aeroflow Performance turbo merge collector range will save you hours of labor when fabricating a manifold and no more wasting material trying to figure out optimal angles. These cast 304 stainless steel merge collectors are a crucial point when it comes to an even flowing exhaust manifold. Each merge collector is cast meaning no welds can potentially crack over time. Available in either 6 into 1 or 4 into 1 configuration with multiple flange options to choose from.
