ProFabrication's merge collectors are engineered to achieve the high flow and velocity necessary to increase and broaden an engine’s torque curve and peak power. Each merge collector is Tig welded and incorporates a transition spike that is internally blended, making the transition from primary tube to collector as smooth as possible, thereby maintaining exhaust velocity and improving volumetric efficiency. 

Our merge collectors are manufactured using fixtures from our tool & die department. This in-house advantage allows us better consistency in our merge collector product line. We stock 12, 15, and 20 degree merge collectors in 4 into 1 and Y-merge collectors.  We manufacture collectors in 2-way, 3-way, 4-way, & 5-way merge collectors.  We also offer Y-Merge Collectors and Offset Merge Collectors.

All collectors can be finished with a collector transition or straight piece (sold separately).
