2008 - 2014 3rd Generation Subaru WRX and WRX STI Hatchback Drone Management System TM (DMS TM) Turbo-Back Performance Exhaust System without Catalytic Converter
by MRT: Hear the Difference, Feel the Performance, Get Noticed!

LOUDNESS RATING: 7 (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: 10 (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)

HEAR THE DIFFERENCE:
  • Add a deep, pleasing performance sound to your Subie WRX or WRX STI hatchback
  • Elimination of factory catalyst increases aggressiveness of exhaust sound and adds louder turbo sound
  • 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
  • MRT’s proprietary Drone Management System TM (DMS TM) includes a tuned resonance chamber specific to this particular cat-back performance exhaust system
  • DMS TM actively manages drone levels to increase the comfort of the driver and passengers inside the vehicle and provide a unique performance sound

FEEL THE PERFORMANCE:
  • Replaces the factory downpipe and eliminates the catalytic converter with larger 3-inch tubing resulting in the fastest possible turbo spooling
  • Larger diameter exhaust tube eliminates the initial restriction point after the turbo of the stock downpipe allowing exhaust gases to flow at a much more rapid rate
  • Mandrel tube bending provides for the smooth flow of exhaust gases
  • 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
  • Larger exhaust tube and lighter weight over stock exhaust system improves gas mileage fuel economy
  • Longer lengths of increased diameter tube of the turbo-back system means even more gas flow and performance improvements than an axle-back system

GET NOTICED:
  • 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!

HANDCRAFTED QUALITY:
  • 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

INSTALLATION:
  • Eliminates factory catalyst
  • Single tip rear fascias require trimming for clearance of quad tips (2008 - 2011)
  • Direct bolt-in upgrade requires no cutting or welding to install and eases re-installation of stock exhaust system
  • MRT engineers this Performance Exhaust System for a simple do-it-yourself (DIY) installation
  • Installation time is about 1 hour and requires only common hand tools

Overall fantastic exhaust October 16, 2017
Reviewed by: Jake Mantz from Colorado Springs , CO United States  
Just installed and was a very easy install in all honesty. Mounts right up to all stock compenents which is fantastic. I Like the fact that everything in the rear that you can see is polished to look good for visual appeal. Sounds amazing, one of the biggest reasons I bought it along with being one of the only products to still have the quad tips. These guys really did an amazing job at designing and perfecting this exhaust, especially the drone management technology. It really works and stays subtle at idle and lights after warmed up and then sounds like a complete beast at wot or even just going through the rmp range. And a big shoutout to Josh in the sales department for helping me out constantly with all my random questions. Can't wait to work with you guys more in the future.


 
 
Best Subaru Exhaust! October 11, 2016
Reviewed by: Corey West from Waterville, OH United States  
This is by far my favorite exhaust available for the 08-14 Subaru.  It is tame when it needs to be, but a monster at WOT.  The quad 4" tips also make it stand out from the rest of the crowd.  With the high quality of materials and craftsmanship I'll driving this exhaust for a long time.  I've also paired the full turbo-back with an external wastegate for the ultimate of fun.  I highly recommend this exhaust to anyone looking for the looks, sound and performance from their Subaru.
