We are very proud to present these extremely affordable CNC cut turbo merge collectors. Huge variety of merge collectors for all flange types that continues to expand. If you are in need of a custom turbo merge collector design or something that is not listed then please contact us.

You will not find similar quality turbo merge collectors for sale anywhere else at a comparable price. Made in-house here at Hotside in Dianella, Western Australia. If you can add them to your cart then they are in stock and ready to ship (we usually achieve same day shipping and have express post option).

CAD designed for a nice fit with any particular turbo flange or V-band flange. Ideally you would blend these with a die grinder after welding to make a smooth and continuous transition from the inlet all the way to the outlet flange - and into the turbine entry.
