RE: TT GP07 Muffler Bolt Spacing
Dave the TT07 muffler bolt spacing is 21mm centres, the bolts are 2.5mm, 25mm long and the muffler is tapped for the bolts, not the exhaust stack-ie the bolts are inserted from the engine side......and though you didn't ask, the muffler weight is 20.9g (22.5g with bolts)

RE: TT GP07 Muffler Bolt Spacing
Thank you ffkiwi. I do need that type of "bolt through" muffler, but I need a muffler with 25mm bolt spacing. Anyone know what the GP10 spacing is?
The OS 871 is 27.5mm; that's too wide.
I know this is a long shot, but I'll ask. Does anyone have an extra ST .11 muffler sitting around?

The Magnum 10 muffler I make as 27.8mm centres-and that is almost certainly the same as the TT GP10 since both are more or less copies of the OS 10FSR

Gotcha RainDave-the original OS Max 10 muffler has 25mm centres. Now the fun-where are you going to get one? It doesn't even have a number on it. Check out Robair81 on Ebay-he has lots of old OS parts

I picked up a little Super Tigre Bluehead Series -X G.11 a while back. The previous owner apparently used pliers on the drive washer, but the interior looks and feels like it was used very little, if at all. I've never seen the muffler for this one come up on eBay, so I figured it would be easier and cheaper to use a readily available muffler.
