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.

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. These are 6" in length. 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.
