This system includes American Racing Headers' Pure Thunder Series mufflers, finished with 4-inch polished stainless steel double wall tips, designed to deliver a deep, throaty exhaust note while minimizing high-pitch rasp and cabin drone.\n\nThis exhaust system is constructed entirely from 304 stainless steel and is 100% Made in the USA. Key features include 3\/8-inch thick laser-cut flanges for a warp-free seal, hand-ported TIG welded inlets, and merge collectors equipped with scavenger spikes. The catted version incorporates 200-cell metallic substrate catalytic converters, chosen for their extreme durability. The primary tube size is 1-7\/8 inches, and the system is 3 inches in diameter, reducing to 2-1\/2 inches at the rear axle to connect with the factory exhaust.\n\nRecent dyno testing of the 1-7\/8\" system with catalytic converters showed gains of 32 RWHP without a tune and 50 RWHP with a tune, alongside a 45 ft-lb increase in RWTQ after tuning. The system includes Flatout Racing Gaskets, OEM-style band clamps, Grade 8 hardware, and O2 sensor harnesses. Optimized primary tube routing is utilized for superior fit and performance.\n\n**IMPORTANT SAFETY AND USAGE INFORMATION:** This product is intended for closed course competition use only and is not legal for sale, use, or installation on highway or street vehicles.
