Exhaust repairs, muffler replacements, catalytic converters, and custom exhaust work for all vehicles.

A damaged or deteriorating exhaust system affects your vehicle's performance, fuel economy, noise levels, and emissions — and it's a WOF failure point. My Vehicle Maintenance in Masterton repairs and replaces exhaust components for all makes and models, from a simple muffler swap to full exhaust system fabrication. Wairarapa's rural roads, gravel, and farm tracks can be tough on exhausts, with stone damage, rust, and broken hangers being common issues we see daily. If your vehicle is louder than usual, you can smell exhaust fumes, or you've failed a WOF on emissions, book in for an exhaust assessment.
Bring your vehicle in or book online — we'll get it on the hoist and check the full exhaust system.

A sudden increase in exhaust noise usually means a hole, crack, or failed gasket somewhere in the system. It could also be a broken exhaust hanger letting a section sag and separate. We'll inspect the full system and find the source.
Yes. Exhaust leaks, excessive noise, and emissions issues are all WOF failure points. If you have a WOF coming up and your exhaust is noisy or damaged, get it checked beforehand to avoid a fail.
Original exhaust systems typically last five to eight years depending on driving conditions. Gravel roads, short trips, and salt exposure accelerate rust. Stainless steel replacements last significantly longer.
Yes. We fit performance exhaust systems and extractors. We'll make sure the setup is legal for road use and WOF-compliant while still improving flow and sound.
