2 1/4" Primary 2 into 1 Performance Merge Collector-18ga 304ss

Our 2 into 1- 18ga (.049") merge collectors are machined and hand fit to perfection. From there, they are purge tig welded and blended for optimal flow. This smooth transition maintains exhaust velocity, improving volumetric efficiency. Available in a variety of merge sizes. This 2 1/4� primary 2 into 1- 18ga (.049") merge collector comes with the inlets expanded to accept a 2 1/4� primary tube. The largest benefit of 18ga (.049") tubing is the weight difference- over 20% weight reduction per merge collector!

Collector Outlet Options:

• Base Exit: Ends at the merge point, select your merge size.
• Straight Exit: The exit size matches the merge size, the outlet is 6" long, and welded to the collector base
• Transitional Exit: The exit size is larger than the merge size, this creates a venturi effect, improving exhaust velocity, and volumetric efficiency. We typically recommend the collector exit size be 1/2" larger than the merge size.

Transition exit size option is for transition exit collectors only.
