Borla systems also combine power with style and quality. Made from full aircraft quality T-304 stainless steel, this exhaust is a split rear exiting system with two Borla embossed 3-1/2 inch oval, rolled edge, angle cut tips at each opening in the rear valence. This system consists of a 2-3/4 inch x-pipe leading to two 19 inch long x 9-1/2 inch wide oval mufflers. Exiting each muffler is a 2-3/4 inch intermediate pipe to each 11 inch long x 10 inch wide rear muffler/tip assembly. R&D testing has shown that this system flows up to 220 cfm more than the factory exhaust (for a total flow of 932 cfm @ 70 inches H2O) and has an increase of up to 16 additional horsepower and 8 ft lbs of torque. Plus, it weighs in at nearly 30 lbs. lighter than the factory system and averages 1.5db louder than the factory exhaust. Complete hardware and instructions are also included. All Borla systems are backed by a one million mile warranty that covers every part of the system, including hardware.
