    Easy install, big sound improvement over stock muffler

    I purchased the Flowmaster after listening to probably over 100 videos of different single axle-back mufflers online. It came down to not wanting my car to sound like an import and the leng of the exhaust tip (not sticking out too far). I can say I am very pleased because after installing the muffler, it fits all my criteria! Install was easy other than having to work the old muffler back and forth for a while to remove it from the pipe. As far as improving gas milage as I have seen some claim, it may take a while for me to see that. I am having too much fun hitting the gas because I can finally hear my engine!! I am looking forward to seeing how it sounds after a couple months of being broken in!

    great product, better than expected sound

    Product arrived, installed next day took less than an hour without jacks. Fit and finish excellent. The exhaust note is so much better than stock. Worth the money
