This system is constructed from 4" mandrel bent 409 stainless steel tubing for 126% more flow, an increase of 18 horsepower, 51 lbs. x ft. of torque and reduced EGT's. This system is finished off with 6" 304 stainless steel intercooled polished tip. Large Bore-HD exhaust systems are the perfect combination of performance, fit and value.
Installation is a Snap:
All systems use factory mounting locations providing stability and hassle-free installation.
Leak-Free Seal:
High quality OE style flange and band clamps are used for a complete 360 degree sealing surface.
Aggressive Sound:
A muffler delete-pipe is used for a true race-inspired sound and maximum flow.
OE Fit:
OE style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The Bayonet tip holds the hanger bushing in place for an OE style fit that does not change with time.
Flow and Performance:
Large Bore-HD exhaust systems are constructed of 4" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.
6" Polished Tip:
Finishing off the exhaust is a high luster, polished 304 stainless steel exhaust tip. This tip features a drain port on the bottom to keep rust and corrosion away. A unique stainless steel laser-cut aFe Power logo plate is riveted on for an aggressive style.
