    Based on 7 reviews

    I love it. Best exhaust ever. Easy self installation too.


    Makes it sounds like a V8 with a smooth, explosive, powerful, and yet still agile performance. 5/5

    Easy everything

    The instal was really straight forward. It took me about 2 hours and that was with zero prior experience changing bike exhaust and some time watching a couple YouTube videos….that were somewhat helpful.
    You will find attaching the muffler clamp to the bracket hanger the hardest part and you’ll need a pair of needle nose pliers to get the washer on and the nut into place. Other than the clamp everything else was really straight forward and easy as pie. The sound is completely different than stock. It’s louder than you think. YouTube videos don’t do it justice unless you crank the volume and get your subwoofer plugged in. I like it. It really does give the bike the growl it needed. 10/10

    Exhaust pipe and muffler look and sound Great!

    First the look is amazing! Such an improvement from the stock exhaust with its bulky Catalytic converter.

    Was a little difficult getting the headers onto the exhaust, had to pry apart and work to get it in place. Very difficult if you don't have a bike lift and doing this lying on your back....but it is possible.

    Can't say enough about the sound...drastically better and love the pops and gurgling when I let off the throttle.

    Overall, very content with my purchase.

    Best Looking, Easy Install, Lamborghini Sounds

    Follow the instructions it’s pretty simple to install. After you remove the fairings (I have R7) if your bike has…it’s Honestly Taking Off 8 to 10 bolts, and putting like 7 back on.

    The headers are one piece you might have to pull the pipes apart a couple cm for to align the pipes to the holes. Once installed and heated up, pipes turn from silver to gold.

    Without DB killer insert the floor will shake upon start up. It’s refreshingly loud compared to stock, it feels like you are actually riding a fast bike. I’d say 3%-5% improved throttle response. If you don’t like gurgles and POPS when u decelerate you will need to tune, I personally get a hit adrenaline every time it pops. Bike will go +5mph easily with no tune. Comes with STICKERS!
