Exhaust Bushings

Exhaust Bushings: the small rubber part that keeps your system quiet and off the floor

Exhaust bushings are the rubber isolators that hang your exhaust system from the hangers welded to the underbody. Each one takes a metal hook or stud and cushions it so the pipe stays supported without transmitting vibration into the chassis. When a stock bushing sags, cracks or perishes, the exhaust drops, rattles against the underside, and can knock at idle. A fresh set of exhaust bushings restores the alignment, keeps tips centered in the bumper cutout, and stops the resonance you feel through the seat.

Enthusiasts also fit firmer bushings on purpose. A stiffer durometer holds a heavier aftermarket system in place better than soft OEM rubber, which is why they go in alongside a cat-back exhaust or axle-back system.

What we stock

This category holds 4 products from 2 brands: Cusco and ISR Performance. Cusco makes up three of the four, with ISR Performance covering the fourth. The current in-stock price range runs from $29 to $30 - that is what is on the shelf now, not a locked-in promise. The product names reference Toyota, Honda and Subaru applications, so read the dimensions carefully rather than assuming a fit.

Concrete examples: the Cusco HD Exhaust Bushing with 11mm hole ID, 40mm hole-to-hole and 26mm thickness and the Cusco HD Exhaust Bushing with 9mm hole ID, 40mm hole-to-hole and 23mm thickness are two-hole HD bushings sized for specific hangers. The ISR Performance Universal Muffler Hanger Bushings are a universal-fit option when you need a set that isn't cut to one vehicle's hanger geometry.

How to choose

The choice comes down to fit versus flexibility. The Cusco HD bushings are dimension-specific - you match the hole ID, the distance between holes, and the thickness to your hanger, and they drop straight in. The ISR Performance bushings are universal, so they cover a wider spread of setups but may need you to confirm the hole and spacing suit your hangers. Measure your existing bushing before ordering: a bushing that is too thin or has the wrong hole spacing will let the exhaust hang crooked.

What else you need with it

Bushings are usually one line item in a larger exhaust job. If you are replacing rubber because the whole system is tired, look at a full cat-back system or cat-back, a new muffler, or exhaust pipes. Header and downpipe work pairs with headers and exhaust flanges. Browse the full Exhaust section to see how the bushings fit into your build.
