Is there anything specific you want to know? I've got a Black edition on my '15 plate and can offer the following advice...installation is a doddle; you WILL need earplugs, they are VERY loud. Fit and finish is exemplary from Race Fit. They're aftermarket support is fantastic too.
Too late on this question but yes I have a Race fit on my 2017 blade. Its not offensive loud, just loud. Beautiful bass tones
You're gonna love it. The only fitting tip I can give you is take your time removing the butterfly cables from the original exhaust. There is a small metal housing around the valve mechanism for which you will need a very small Phillips screw driver. I removed the exhaust but I didn't do a full removal of the cables. Instead I cable tied them together and tucked them away. Post a pic when you're done so we can admire it
Yeah I had a Pipewerx on my 14 blade so should be straight forward enough. Yeah I’ll post a pic when it’s on
