These band-style stainless steel clamps give you a 360 degree seal without crimping the exhaust pipe. They can be used for butt-joints (two pipes with the same diameter) or for applications where one pipe fits into the other.  These clamps will stretch giving you a leak-free seal. The polished T-304 stainless steel clamps resist corrosion. They come with pre-attached hardware and Grade 8 bolts for high strength and temperature durability. They're ideal for applications where future removal of the exhaust is necessary. Made in the USA.
