PPE 3.5" Exhaust Bellows (Universal)

This is a PPE exhaust bellows measuring 3.5″ diameter x 2.875″ long. It is a universal flexible section for exhaust and downpipe plumbing.

A bellows lets the exhaust flex with engine movement, thermal growth, and vibration instead of transmitting all that load into rigid pipe and welds. That flexibility is what prevents cracked tubes and broken joints over time.

It is a common piece in custom turbo-back and downpipe builds, and a good repair item where an exhaust section needs a flex joint to survive drivetrain movement.

Weld or clamp it into a 3.5″ exhaust run at the point that needs flex. Backed by a 1-year limited warranty.
