ATLAS  exhaust systems utilize a 2-piece tailpipe design for a perfect fit by  allowing adjustability at the tailpipe section. All systems use factory  mounting locations providing stability and hassle-free installation.

Leak-Free Seal: High quality OE  style band clamps are used for a complete 360º sealing surface. Standard  U-bolt clamps used by other systems only seal at the bottom and top of  the tube allowing leak paths.

Aggressive Sound: A free-flowing  12" wide muffler is used to absorb high pitch tones producing a powerful  sound and unleashing all available horsepower and torque out of your  rig.

Perfect 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.

Note: This is a "Race Only"  product used soley for competition. It's use is limited to  closed-course and open-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
