I have the Mufflex set up on mine and am pretty happy with it. The install was easy and it took a little work to get the tips lined up on mine, seems a hit or miss for some people, but overall for the price I'm not complaining. I wish it was a little louder at times but I have zero highway drone or error codes so I'm happy
Also the tips do stick out a little further than the stock tips, if that would bother you, but I don't think it looks bad. I can take a picture if you're curious.
