When GM released the new LS3 powered Chevy SS, they quickly filled the void created when the Pontiac G8 was eliminated. With over 400 HP to start with, we knew we could produce considerably gains with our long tube header system. How much more? With Stock mufflers we produced over 30 RWHP and 32 RW Torque before tuning. With tuning and a quality Cold Air Intake you can see up to 50 RWHP. Primary sizes available are 1-7/8" or 2" with 3" collectors followed by a 3" X-pipe system that extends back to a 2-1/2" rear section complete with our direct fit quad tip Pure Thunder mufflers. Our 100% US made mufflers are 304 S/S with a straight thru design and feature (two per side) 3" double walled polished S/S tips that fill the stock opening of the rear valance quite nicely. Expect a deep, throaty sound with little to no rasp and minimal drone. With high quality hardware included, expect a great fit and easy installation as always on ARH systems Product features on this system includes: 100% Made in the USA - Never Outsourced Made entirely of 304 stainless steel 3/8" thick laser-cut flanges for a warp-free seal Hand-ported TIG welded inlets Optimized primary tube routing for superior fit and performance Merge collectors with scavenger spikes Catted systems feature severe duty 300 cell catalytic converters with the option to upgrade to 400 cell G-Sport catalytic converters.
