Installation tips (quick & reliable)
- Slide the U-bolt around the outside of the pipe(s) to be joined and place the saddle plate over the threads.
- Hand-thread the nuts onto the U-bolt studs, making sure the saddle plate sits square and the clamp centers on the joint.
- Alternate tightening the nuts a little at a time with a socket or wrench until the clamp is snug — avoid over-tightening to prevent deforming thin-walled pipes.
- Check for exhaust leaks at idle and under load; re-torque if needed after a short test drive once the clamp has settled.

Benefits vs. welding
U-bolt clamps provide a fast, reversible connection without heat, making them safer and cheaper for many repairs. They’re ideal when you need a quick, serviceable joint or when welding access is difficult. For permanent installations where appearance and zero leakage are critical, welding may still be preferred — but clamps are a dependable alternative for the vast majority of maintenance tasks.
Buy now — 2 PackFrequently Asked Questions
- Will this clamp fit any 2.5" pipe?
- Yes — this clamp is sized for pipes with an outer diameter close to 2.5" (63.5 mm). If you have thicker custom pipes, verify the exact OD before purchase.
- Is the stainless steel marine-grade?
- The clamps are made from 304-grade stainless steel, which offers excellent corrosion resistance for automotive use. For high-chloride marine environments, consider 316 stainless fasteners for extra protection.
- Can I tighten these clamps too much?
- Avoid excessive torque. Tighten evenly until secure and then recheck after a short drive. Over-tightening may deform thin exhaust tubing and create gaps.
