My tractor was missing the factory exhaust from the previous owner. He had the orginal muffler, but was missing the exhaust extension and support bracket. I ordered the $150 part from my CC dealer and proceded to bolt it all together, 1/2 way through my 3 acre lawn the part failed. I returned the part, dealer got me a new one, and this one failed the same way. Do not waste your money on this part BAD design! Failure anaylisis: CC made the center tube out of stainless steel and brazed the tube to the steel support bracket and the muffler flange. That heavy muffler and heat shields cannot be supported by the stainless. I reworked the brackets so the extension tube could be made out of 1/4" wall DOM tubing, added addtional 1/2 length as well. After welding everthing back together I mill filed the flanges flat. Re assembled everything with new blots and gaskets and no issues.
