Okay, so, today I’m gonna talk about my little project with my ’05 R6. I’ve been itching to mess around with the exhaust system for a while now, and I finally got around to it. It’s nothing too fancy, just wanted to give my bike a bit more of a growl, you know?

First thing I did was look around online, just to get an idea of what other people were doing. Saw a bunch of folks talking about “cat-back” systems and “slip-ons.” Didn’t really know what those were at first, had to do some digging. Turns out, cat-back means replacing everything from the catalytic converter back, and slip-on is just swapping out the muffler. I decided on a slip on.
- I started by taking off the stock muffler.
- A few bolts here and there.
- Some wiggling around.
It wasn’t too bad. I’m not a mechanic, but if you can turn a wrench, you can probably do it.
Then came the fun part – picking out a new muffler. I read a ton of reviews, checked out some forums, and finally settled on one that seemed like a good balance of sound and, well, not being obnoxious. I ended up going with a Spark Exhaust Technology Italy for the 08-16 R6, just cause I heard some good things about it and saw it mentioned a lot.
Putting the new one on was pretty much the same as taking the old one off, just in reverse.
- Bolted it up.
- Made sure everything was tight.
- Started it up.
Man, let me tell you, it sounds way better. Not crazy loud, but definitely has more of a presence. It’s like my R6 cleared its throat, you know?

I also messed around with the exhaust tip a little. Found one with dual walls that’s supposed to amplify the sound a bit. I’m not sure if it makes a huge difference, but it definitely looks cooler, so that’s a plus.
All in all, I’m pretty happy with how it turned out. It wasn’t a huge project, didn’t cost a ton of money, and it made a noticeable difference in how my bike sounds and feels. If you’re thinking about doing something similar, I’d say go for it. Just do your research, pick out some parts you like, and don’t be afraid to get your hands dirty.
One thing I learned, though, is that if you really want to go all out, a full system is the way to go. That’s where you replace everything, from the headers to the tailpipe. Apparently, that’s where you get the biggest gains in terms of sound and performance. Maybe I’ll do that someday, but for now, I’m happy with my little slip-on.
Oh, and one more thing I found while I was reading up on all this stuff – there are these things called baffles. They’re basically like little inserts that go inside the muffler to control the sound. Some mufflers have them, some don’t. The one I got has limited baffles, which probably contributes to the louder sound.
So yeah, that’s my exhaust story. Not the most exciting thing in the world, but it was a fun little project, and I’m happy with the results. If you’re into cars or bikes, I definitely recommend tinkering around with stuff like this. It’s a good way to learn more about your ride and make it your own.
