    5 of 5 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.

    5 of 5 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.
