Got them on today, sound really good, weather too bad too take her out. Haven't installed the M4 Stage 2 Inserts yet, may not, they don't seem too loud.

there's a big difference between stock and M4's

Man I am between those M4's and gravesport carbon. I have a matte black with red accents 14' and the powder coating/satin coating on those M4's would really match the blackness of my bike. You say they aren't that loud without the silencers? I'm curious how you feel about them after a ride with a helmet on? I checked your pics of your old Raider, my other bike is an 09' raven Raider I was going to sell it, but I couldn't do it. So now there is two bikes in the stable. The way I figure it, once the newness rubs off the ZX14 I will be switching rather frequently. Give us a ride report when you have some time bro!

Sweet I will say although I liked the stockers (over time) the more options I see the more I like everything else way better! I bet those suckers be very loud though, like pj says until you're riding it's a huge question as to how loud they really are. Those look like 10 mile pipes to me!

After an afternoon of riding, the sound started getting annoying so I decided to install the stage 2 inserts, perfect! They sound great, I'm very happy with these slip ons. Just going to take some time getting used to all that space on my rear end!

The Gravesports look good too, good luck deciding. I wish I kept my Raider, it was fun. But if you decide on the M4's, get the stage 2 baffles.
Check out this vid, M's with the baffles in.

Thanks bro! I actually watched smatlock's video today. They sound good for sure. I will definitely purchase the baffles.
