thanks,had not thought of that.the old muffler was attached to the engine.i will definitely take your advise..

I have never had any luck usin hose clamps in extreme heat apps. replace it with a standard muffler clamp.

muffler clamp as the hose clamp cannot generate enough clamping force on the metal to keep it on.
Or just weld it together - I brazed my last one together and it lasted about 9months. Would suggest mig welding for more strength
