This allen... if you remove it the insert should be able to be pulled out...

There may be more than one screw holding it in, take the canister back off and inspect it carefully and see if there are an allen or two holding that inner sleeve in. Don't start drilling your $500 slip-on until you are SURE the insert doesn't just come out like Yosh says it will. If you are still in doubt then for God's sakes call Yoshimura @ 800 634 9166.

That or it can be because you still have the cat on there. The stock muffler has no silencing feature at all. I replaced the cat on my '09 r6 and kept the stock muffler on and my bike's loud as fuck now. The cat does most of the silencing, this could add or be the reason why it's pretty quiet.

Yea you're probably right, I called it the "under" muffler... Did the '07 have a converter? What I do know is that there is an insert that can be removed in many Yosh models. We did my buddy's GSXR600 last year and I almost begged him to put the silencer back in! OMG fucking loud! Like you said, we removed the muffler/exhaust tip and the "under-muffler" on muffler/converter combo. Anyway, before anyone breaks out a fucking drill, they should first determine what model slip-on they have (wasn't mentioned in OP) and give Yoshimura a call!

The Yoshi I had on my last bike ('06 R6s) had that, it was wasy to pull out and that's the sound/volume I am looking for.

Don't worry, I won't do anything without checking with Yoshimura or have a mechanic do it for me.

The 08 and 09 GSXR600/750s had the cat welded to the header. You could pull the stock can and put on any aftermarket slip on and it doesn't change sound or performance. You might have the same thing going on. If your cat is not welded on pull it off and have a pipe custom fitted to go between the slip on and the header.

All '06+ new bodies have a cat.

I just yanked my silencer out last night. It was a beeyotch.

Well, was it technically held in with an allen head screw? Seriously, one thing I've found with the inserts is if you leave them in for a while they are MURDER to get out and if you leave them out for a while, you can forget ever getting it back in!

Thank you sir! Appreciate the phone number.

That makes sense. Thanks!
