I have a 25' Caliber1 with 4" x 6" exhaust tip (part # 100-16?). It has a silencer (part#102-07?) spot welded in. Can I grind those 3 welds off and will the silencer come out or is it welded on other end too? I'd like to remove them and weld a nut on it and be able to put it back in when I need to, just like the one in the catalog(#102-07).
