  • The exhaust looks and sounds amazing. Very loud without DB killer and still plenty loud with it, but the sound is really really good either way you go. Instructions from SC Project were a little vague; had some trouble with fitment at first using the included bracket… but the customer service from motovation was top notch. I reached out with my concerns and Jacob was very quick to respond and helped talk me through trying some different ways to get it to work. After a couple days and a couple phone calls, I was able to get it installed and it fits perfectly thanks to their help. Always helps justify dropping a good chunk of money on something when the company cares about your purchase and goes the extra mile to make sure the customer is happy and that everything works right.
    Overall, couldn’t be happier with the exhaust, sounds better than a lot of others that I’ve heard on this motor.
