Borla's Touring series is the quietest of its three sound levels, a mellow, deep note that stays out of the cabin instead of droning at highway cruise, which is what makes it the sensible choice on a truck that also has to haul. The system is fabricated entirely from T-304 austenitic stainless steel rather than the aluminized or 400 series tubing most cat-backs use, and Borla's patented straight through, multi core muffler design carries the flow without the packing that burns out of a chambered muffler. A single 2.75 in inlet splits into dual 2.25 in mandrel bent tailpipes and exits split side ahead of the rear tires, finishing in a pair of 4 in round, rolled and angle cut bright chrome tips. It covers the 4.8L, 5.3L and 6.0L V8 in extended cab short bed trucks, in 2WD or 4WD, and carries Borla's Million Mile Warranty.
