    Installed in minutes on my 2018 zx14r. Pulling them out of the box I was stunned at the Flawless smooth ceramic coating. When I fired the bike up the first time I was blown away at the sound. Way better than I even hoped. It was so deep, mean and angry sounding but not trashy like shorty pipe. You can tell they put a lot of engineering into the sound of this pipe. This is by far the best sounding and best looking pipe I've ever come across it will make your ZX-14 sound exactly like it should, trust me this is THE pipe you've been looking for. I'm running stock header with no retune and no backfiring and sounds incredible. With the stock baffle it has a low Bassy sub type of sound until you rev it up and it will scream like an F1 car. All of the YouTube clips I watched online did zero Justice for this Muffler you must hear it in person. Thank you sportbiketrackgear for getting this in my hands in 2 days incredible!

    Great quality at a great price

    Purchased these for 2016 ZX-14R. I like the look of the dual exhaust but the big, heavy, bulky stock mufflers are dangerously quiet. I am NOT running the quiet inserts and the stock cat inside the collector is still there. The bike is slightly loud for residential neighborhoods but sounds great on the open road or at the strip. Easy to install and fits like it came from the factory.
