got a 3 inch wet exhaust run and the pipe dont line up perfect. is this single hump bellow meant to take up that kind of misalignment and vibration

Answer by: Customer Support on Jan 20, 2026, 6:06 PM

Built for wet exhaust systems, the single hump section is there to absorb misalignment, movement, and vibration. It also helps cut down back pressure and noise compared to a rigid straight connection.

How much wiggle room does this hose give me if my exhaust isn't perfectly lined up?

Answer by: Customer Support on Feb 19, 2026, 9:00 PM

It's designed with a single hump that allows for some misalignment, movement, and vibration in your wet exhaust system. The hump is 4.5 inches in outer diameter, which should provide a good bit of flexibility.

Question by: Rod S on Aug 17, 2025, 3:21 PM

clamps come with this or do I need to order them separate?

Answer by: Customer Support on Aug 18, 2025, 8:50 PM

Clamps are included with the hose, so you won't need to track those down separately. That said, the installation notes call for a minimum of two stainless steel clamps at each end, at least half an inch wide. The included clamps should cover your basic needs, but if you're going with T-bolt or constant torque clamps for a more secure setup, those are worth picking up on their own. Just make sure whatever you use meets that half-inch minimum width requirement.
