CORSA 14311 Pro-Series 2.5" Stainless Steel Sport Axle-Back Exhaust System Kit

I put these on a 2008 Mustang Shelby GT500 with Kooks long tube headers, an off-road three inch X pipe and also "had" Flowmasters on the axle-back with welded on Shelby tips. I had no real idea how bad my drone problem was until I replaced the axle-back with these. I was simply amazed that these worked so well at eliminating drone noise. I actually thought at one point that the car shut off because it was so quick inside. At idle, the axle-backs sounded very manageable and deep sounding. Normal driving is where the sound of these starts to wake up. These are louder than my old mufflers but not enough to bother the neighbor if I drive with caution. If I were to light it up the car would most certainly wake everyone on my street up. Final verdict is I made the right choice in getting these to eliminate my drone problems and the sounds of these are just music to my ears.

As expected these axlebacks are great quality! Good clean sound, loud but not crazy loud. Installation was really easy and took maybe 45 minutes. There is a YouTube video from American muscle that shows you how to do it to make things as easy as possible! All that’s left is to get an X Pipe next!

I haven't had these installed yet, but the quality is amazing, as is the polished stainless look. Corsa is a highly reputable muffler and you cannot beat the true LIFETIME warranty.

They are as advertised. Great sound, performance and looks. This along with a cold air intake gives amazing performance over stock.
