aFe is proud to introduce all new header/Y-pipe combos for the 2014-2015 GM Silverado/Sierra 1500 with V8-5.3L engine. aFe now offers performance Twisted Steel long tube headers with a high-flowing y-pipe for value and added performance.
The performance headers and y-pipes are available with 400 CPSI, 48-state legal cats or in a “Race” version. In testing the catted version resulted in gains up to +12 horsepower and +13 lbs. x ft. of torque, as measured on our in house dyno.
The performance long-tube headers are constructed of 1-3/4” 16 gauge mandrel-bent tubing for strength and durability. A 4-to-1 formed collector is used on the header to decrease turbulence and increase exhaust velocity for maximum performance. The high-flowing y-pipes are designed using a mitered merge collector with 3” to 3-1/2” tubing transition for optimum flow resulting in added horse power and torque.
These systems are designed to fit in the stock location incorporating 02 sensor locations with all necessary hardware for a hassle-free installation.
