EXO Stainless is the most durable exhaust in our lineup. Constructed of high-strength 304 stainless steel from front to back, EXO Stainless is sure to withstand even the most brutal of riding conditions and use. We took the original EXO Series and swapped out the aluminum muffler for a stainless muffler, replaced the aluminum base plate with a TIG-welded stainless steel plate and added a trick looking stamped stainless badge to top it off.
