2 1/2" Primary 4 into 1 Performance Merge Collector-18ga 321ss
Performance Slip-On Merge Collectors: 2 1/2" 4 into 1- 18ga (.049")
Our 4 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 volume to efficiency. Available in a variety of merge sizes. This 2 1/2� primary 4 into 1- 18ga (.049") merge collector comes with the inlets expanded to accept a 2 1/2� primary tube. If you would like to add collector tabs to your custom collector, let us know in the order comments at checkout. The largest benefit of 18ga (.049") tubing is the weight difference- over 20% weight reduction per merge collector!
These 321 Stainless Steel Merge Collectors are ideal for any high boost or heavy nitrous application due to the improved metal qualities not found in other types of 300 series stainless steel.
For Transitional Exit Merge Collectors, the typical transition exit size is 1/2" larger than the merge size.�
