Anyone have any experience with the MIVV GP Pro and No-Kat Pipe? I eventually want to add a Rapid Bike EVO which I know would be best if going beyond just a slip-on muffler but not ready for everything all at once. I also like the look of the Competition Werkes GP Slip-on with the option to add the cat and mid pipe delete later. From what I've read though it seems like the Competition Werkes often has problems with needing repacking and is really loud. I have a 2018 RC 390 though and not sure if that was just the case with the pre 2017 models.

If you're doing more than a slip on, it's best to get a fuel controller first to avoid damage from running lean. I'm playing it safe and installed just the slip on for my first few months. Once my PCV, custom airbox, big injector, open lid, filter and decat pipe come later this week, I'll been slapping it all together Friday night. My PCV is coming from Rottweiler with a tune for the supporting mods so we'll see what shakes out
