The EXO Stainless series from Big Gun� is the most durable exhaust in their lineup and can withstand even the most brutal of riding conditions. This performance-driven, quality-made full exhaust system is almost identical to the original EXO Series but features high-strength 304 stainless steel construction from front to back and a unique hexagon shape that allows for significantly more volume. EXO Stainless series will deliver a louder but more tolerable deep sound that is sure to make even a grown man feel like a kid again.
