aFe Part # 49-33072-B (Black Tips), # 49-33072-P (Polished Tips) are Mach Force-XP cat-back exhaust systems for the 2015+ Ford Mustang GT with the V8-5.0L engine. In testing, this system resulted in gains up to +11 horsepower and +14 lbs. x ft. of torque @ wheels.  This cat-back exhaust system utilizes full 3” tubing with clamp-on reduction tubes to fit OE connections which can be removed when fitting aFe Powers full length Twisted Steel long tube headers to take full advantage of flow and even more power.  aFe also designed this unique system with an X-pipe to balance and evenly distribute exhaust pulses traveling through the exhaust system. This not only creates a more efficient flow and better performance but also reduces decibels minimizing exhaust drone giving you an awesome sound. To finish off the exhaust, dual 4" gloss black 304 stainless steel tips are included.  

   

  

  

   aFe part # 48-33012-YC is a set of Twisted Steel long tube catted headers/connection pipes combo for the 2015+ Mustang  GT with V8-5.0L engine.  In testing, this system resulted in gains up to +13 horsepower and +19 lbs. x ft. of torque, as measured on our in-house dyno @ wheels.  Designed to replace the extremely restrictive exhaust manifold, the performance Twisted Steel long-tube headers are constructed of 1-7/8”, 16 gauge, mandrel-bent, 304 stainless steel tubing for strength and durability.  A 4-to-1 formed collector is used on the headers to decrease turbulence and increase exhaust velocity for maximum performance.  The high-flowing connection pipes are designed using 48-state legal 200 cell catalytic converters and mandrel-bent, 304 stainless steel tubing for optimum flow resulting in added horse power and torque.  This kits also includes 3” adapters to attach to the aFe power cat-back exhaust system (49-33072-B/P) for even more flow and performance.
