    by MRT: Hear the Difference, Feel the Performance, Get Noticed!

    LOUDNESS RATING: 6 (On a scale of 1 to 10 with 1 being stock and 10 being OMG loud, when all other components are stock)

    DRONE RATING: 2 (On a scale of 1 to 10 with 1 being stock and 10 being intolerable, when all other components are stock)

    PERFORMANCE RATING: 8.5 (On a scale of 1 to 10 with 1 being stock and 10 being the maximum possible performance gain from an exhaust system, when all other components are stock)

    • Add a deep, pleasing performance sound to your Subie WRX or WRX STI sedan
    • Straight through sound absorbing muffler produces a deep and refined performance sound from idle throughout the RPM range
    • Resist the urge to put your foot in it to keep the RPMs and sound levels lower
    • Wide open throttle increases exhaust loudness and tone to an aggressive performance sound
    • If deep performance sound that becomes louder as you increase your acceleration fits your desire, this is the system for you

    • Straight through muffler design provides for maximum exhaust gas flow
    • Larger exhaust tube reduces weight and exhaust gas flow restrictions producing noticeable performance gains
    • Higher exhaust flow prepares for future performance modifications
    • Lighter weight assembly as compared to stock exhaust system improves all aspects of performance
    • Higher exhaust flow and lighter weight improves gas mileage fuel economy
    • Cat-back system eliminates the factory mufflers for added power and weight reduction
    • Longer lengths of increased diameter tube of the cat-back system means even more gas flow and performance improvements than an axle-back system

    • Quad 4-inch double wall, polished T304 stainless steel tips with beveled edges add style to your ride
    • If you prefer a blackout look for the exhaust tips, choose the matte black Cerakote finish
    • Great sound and great looks turn heads and get positive comments!

    • Industry exclusive 100% T304 stainless steel straight through mufflers
    • Constructed from corrosion resistant T304 stainless steel tube, the best quality stainless steel for exhaust systems
    • All component parts (hangers, clamps, bolts) are stainless steel
    • CNC mandrel bending technology for precise fit
    • Unique proprietary manufacturing and quality control process produces the highest quality constructed and best fitting exhaust in the industry
    • Developed and handcrafted in-house at our facility in Plymouth Michigan USA
    • Backed by industry leading Limited Lifetime Warranty

    Great Cat-Back! October 11, 2016

    I have this on my 2011 WRX sedan shown in the video above.  It carries a lot of the characteristics of the full turbo-back with a touch less of volume when used with the stock down-pipe.  Fitment, quality and finish is superb!  I can't get enough of the quad 4" tips helping it to stand out from the crowd.  I highly recommend this to anyone looking to keep this OEM+ look, but enough grunt to show you mean business.
