I am just wondering if anyone has tried hollowing out a stock muffler yet? I got a 08 650R and I have to admit I am cheap and don't want to spend a few hundred on a slip-on but do need some more noise.
IMHO it sounds like shit. It will give you more noise if you drill some holes in certain spots. (Check Youtube). It sounds a little be raspier, and kinda rattly. You dont have to spend a shit ton on a slip on. Check ebay, craigslist, ninja 650.com for sale area, etc, etc.
I've been watching and biding on ebay but people bid almost up to the cost of a new slip on and for a $30-$40 difference i'de rather have a new one. I did get a stock exhaust for $4.99 and am going to try out some things and see what happens. I've checked youtube and the speakers on my laptop aren't very good for judging sound. I'm going to hold on to my original exhaust just in case it does sound like crap.
