...no really, and here's why;

I purchased a 4 inch silencer for my Hayame. I had THOUGHT my muffler was 4 inches but it turns out it's metric :doh:. This means the exhaust tip is about 2 to 4 mm to small for the silencer.

I'm desperate to get this bastard on and I'm hoping there's a way to either widen the tip slightly, or shrink the silencer.

I spent months searching for this silencer so I would hate to have to toss it

help!! :awais:
