aFe Large Bore-HD exhaust systems are the perfect combination of performance, fit, and value and feature:

* Leak-free 360 degree sealing
* Stable pipe location in high-vibration and high-heat conditions
* Bayonet tips hold hanger bushings in place for an OE-style fit
* Large diameter tubing provides maximum flow
* Smooth bends for low turbulence, increased horsepower and torque, and lower exhaust gas temperatures (EGTs)
* Slash-cut tips with intercooling vents reduce EGTs at the tailpipe (most applications)
* Available in DPF-back, cat-back, turbo-back, and downpipe-back configurations (varies by model)
* Select systems include dual outlets and exhaust tips

Note: Some of these systems are "Race Only" products sold solely for competition use. Their use is limited to closed-course racing that is formally sanctioned by a recognized racing organization. Any other use, including recreational off-road use, could be in violation of local, state, and federal laws.
