Exhaust Bracket & Bushing FAQs
How do I choose the correct Peterbilt exhaust bracket?
Compare the existing bracket’s base shape, mounting position and attachment points with the product specifications. Check any listed OE reference and application. Model name alone does not confirm compatibility, particularly if the exhaust system has been modified.
Are straight and angled exhaust brackets interchangeable?
Do not assume they are interchangeable. Bracket shape and base profile can differ. For example, the listed 21325 angled bracket has a curved base; compare the actual mounting arrangement before selecting a replacement.
What do exhaust bracket bushings do?
Bushings help isolate movement and vibration within the matching exhaust bracket arrangement. The individual Peterbilt bushing listing specifies polyurethane and a male/female design. Match the design and dimensions to the existing mount.
Can I buy a single bushing or a pack?
This category includes an individual exhaust bushing listing and a separately listed four-pack. Check the included-parts section and pack quantity on the exact product to order the amount required.
Is the rubber gasket the same as an exhaust pipe sealing gasket?
The listed rubber gasket is for a Peterbilt 359/379 exhaust bracket. Select it for the specified bracket arrangement; do not assume it is a gasket for sealing an exhaust pipe joint.
Are clamps, bushings and hardware included with a bracket?
Review each product’s included-parts section. The 21325 angled bracket listing specifies one bracket and asks buyers to confirm the gasket, bushings and mounting hardware separately. Other listings may differ.
Are all the brackets made from 304 stainless steel?
Check the exact listing. The 21325 angled bracket explicitly specifies polished 304 stainless steel. Other stainless bracket listings should be checked individually; a stainless description alone does not establish the grade.
