Cheap exhaust

[porthyt]

Wowzer that's a lot of work. Thanks for the replies. Seems a lot though and perhaps I haven't explained. The bolts that have snapped are the ones between the backbox/silencer and the heat exchanger. 2 on the bottom and one on top on each side but I can see the other side of the bolt albeit a sort of pan head.?

It's a n air cooled early 80's petrol.

It doesn't matter the studs are not reused cut them off, the new silencer should have come with new studs in the fitting kit that screw into the silencer.

Cheers HErb. Sir I went and bought me a grinder which solved the problem pretty sharpish. Knocked out the old bolts. But no new ones in packet so off to buy some stainless ones tomorrow.

Should I use any type of sealant type stuff between the heat exchanger and the exhaust silencer. I have the gasket but not sure if I need exhaust paste as well??? The metal on the flange isn't exactly smooth so am worried that the gasket won't seal entirely. What do you guys use?

Cheers

They will squash up enough to remove any imperfections although if you're careful you could linish them smooth with some emery paper on a block.

Covkid re your comment about annoying resonance with a bike silencer. Driving up a steep single lane between houses in second. I bet I annoyed the spanish residents. It annoyed me and I was ahead of it.

Hehe. It does depend on can used but yes, stealth driving could prove troublesome. Normally its just a rumble but in 2nd.....
