Yes I do. Send me your information, and I will send it out.
What's it look like? I have a 77, can looks like it runs straight through though. Pics?
Mine has a rubber plug on the cone and a set screw under.
Yes, I stand corrected, my can has the rubber plug as well. I was confusing mine with one I put on a GSX-R1000 at work recently... it had a small tab on the cone that needed to be removed.
Honestly I couldn't tell you. I never installed it, didn't think the r77 was that loud. It's not something you have to remove, it's something you have to install.
It's noticeable...... according to my neighbor. LoL! i feel like it did make a difference too. Like said above, they don't come with them installed. The holes are actually pre drilled and you have to take a punch and knock out the little metal circle to open the holes so you can secure the baffles with the small Allen bolts. The hardware comes in a bag. According to member sixpack, the EPA compliant r77s come with them installed and riveted in place so they can't be removed(at least not as easy to do).How much difference does one make? After reading this thread I checked for mine, and it seems the orig. owner removed it already.
That sounds different. There is no nut. The baffles have a threaded hole that lines up with the hole on the muffler itself. All you do is slide baffle in and line up everything and then screw the bolt in. After that you put your little rubber plug back on to cover the hole through which you put the screw in and done. Wish I was home to take some pics.My bikes got the rubber plug, allen bolt and nut. Just no baffle. I'm assuming then that it was once installed. As there is no "knockout", but instead a bolt and nut.
