Dorman Exhaust Clamp replacement for Buick/Chevy compact models — 667-523, durable corrosion-resistant fit

The Dorman 667-523 Exhaust Clamp is a direct-replacement exhaust fastener engineered to restore secure, leak-resistant joins between exhaust components on specified Buick and Chevrolet vehicles.

When an exhaust connection becomes loose or rusty, vibrations, noise and exhaust leaks can follow. The Dorman 667-523 clamp is manufactured to match the fit and function of the original equipment part for a range of compact GM models, offering a straightforward way to repair or maintain the exhaust system without costly assemblies. It’s made from durable materials and produced to strict specifications so you can re-secure pipe and muffler joints quickly.

Which vehicles does this clamp fit and how do I confirm compatibility?

This clamp covers many Buick and Chevrolet compact models across specific production years. Always verify fitment for your exact vehicle trim before buying to avoid returns or improper fit.

• Compatible models include Buick Encore (2013–2021), Chevrolet Cruze and Cruze Limited (2011–2016 years as listed), Chevrolet Sonic (2012–2020), and Chevrolet Trax (2013–2021).
• Use the site’s garage/fitment tool to select make, model and trim for a precise match.
• Designed to replicate original mounting points and clamping geometry for these vehicle applications.

How does this clamp help when I’m replacing or repairing exhaust parts?

The clamp restores a tight mechanical connection between exhaust pipes, hangers and muffler flanges so components remain sealed and aligned under heat, vibration and driving loads. It’s a practical fix for spots where a welded joint isn’t necessary or when replacing sections of the exhaust system.

• Secures pipe-to-pipe or pipe-to-flange joins to reduce exhaust leaks and noise.
• Simple installation with hand or basic mechanic tools—no specialized welding required for many repairs.
• Helps retain factory alignment and clearance to prevent rubbing on chassis or bodywork.

What materials and quality controls are used in this exhaust clamp?

Dorman manufactures replacement components under controlled processes to deliver consistent performance and corrosion resistance appropriate for exhaust service. The clamp’s construction is chosen to withstand thermal cycling and road-exposure conditions common to underbody parts.

• Constructed from materials selected for strength and durability in exhaust environments.
• Produced to match OEM dimensions and function to ensure reliable connections.
• Backed by Dorman’s product development and quality oversight for automotive replacement parts.

What should I know about installation and maintenance?

Installation is straightforward for anyone comfortable with basic under-car work. Use proper torque and ensure mating surfaces are clean to achieve the best seal and service life. Inspect clamped joints periodically for corrosion or loosening, especially in winter climates.

• Clean mating pipe ends and remove heavy rust before fitting the clamp.
• Tighten fasteners evenly to the vehicle manufacturer’s recommended torque when available.
• Check clamp condition during routine service and replace if severely corroded or deformed.

Who is this for: The Dorman 667-523 Exhaust Clamp is intended for owners, DIY mechanics and repair shops working on Buick Encore, Chevrolet Cruze, Sonic and Trax models listed in the fitment range who need a reliable OE-style clamp for exhaust repairs or replacements. It suits anyone seeking a durable, direct-fit replacement clamp to restore secure exhaust connections without extensive fabrication or welding.
