Yeah, I do. Can I get the pic with a quick write up on how to rivet the cap back on? I still don't know how to rivet. (even though I should)
Taking the end cap off is pretty easy...just drill out the existing rivets, starting with a small drill bit and working your way up until the rivet comes out for you. Once you know the right size to use, just use that size on all remaining rivets. Once they are all drilled out, the end just pulls off. Be careful not to push the drill to hard when you are drilling out the rivets as you will push your drill into the packing of the muffler...not a big deal, you just dont want too much wrapped around the drill bit. I did have a little bit on my first couple, if I remember correctly, but it made no difference at all....just something to keep in mind.
Then there is a metric hex nut in the underside that you need to remove. Once that is out, the baffles pull out very easily. If you never plan to put the baffles back in, then dont bother drilling a hole in the underside of the can, as you will never need it.
If you do want the hole, just put something straight down through the hole that the bolt was in, so that you can mark the end cap, as to where you need the hole. I went with a hole a little bigger than the head of the bolt so it could easily be taken down through without risk of losing it....not a big deal if you did lose it inside, as there is nothing there that could be damaged.
As for installing the end cap...you need a rivet gun and rivets. Most guns come with a good selection of sizes so you dont need to buy more. If you've never used a gun before, just do some playing with rivets and a piece of sheet metal or something to figure out exactly how it works. As for picking rivet size, just make sure it fits snugly into the hole, as that is the principle of the rivet cutting itself off. Its pretty simple to figure out once you have the gun in your hand and some metal to drill holes in and play with.
Here are a couple of pics of the exhaust, with no baffle
Here is a pic of the baffle itself.
I hope this helps you a little. If you have any more questions, just let me know.
