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.
