This system is constructed from 4" mandrel-bent 409 stainless steel tubing and uses high quality band clamps and OE-style bayonet hangers. This unit uses all factory mounting locations and comes with a bolt-on bracket that supports the driverside tailpipe. This provides for a quick, hassle-free installation with no modification necessary. Also included in this exhaust system is a massive 6" polished 304 stainless steel tip with a laser-cut stainless steel aFe power badge. Large Bore-HD exhaust systems are the perfect combination of performance, fit and value.

Single To Dual Exhaust Conversion:

This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust.

Simple Installation:

All systems use factory mounting locations providing stability and hassle-free installation.

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:

This Large Bore-HD exhaust system is 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.

Polished Tips:

Finishing off the exhaust are dual high luster, polished 304 stainless steel slash-cut tips. The tips feature a drain port on the bottom to keep rust and corrosion away.
