Flow and Performance:
This Large Bore-HD exhaust system is 100% hand MIG-welded and Constructed from 4" mandrel-bent stainless steel tubing for maximum flow. The smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.

The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time.

6" Angle-Cut Rolled Clamp-On Tips:
Finishing off the exhaust is your choice of polished or coated black dual side exit 6" stainless steel clamp-on tips. A unique laser-cut aFe Power logo plate is riveted on for an aggressive style.
