Exhaust Repair & Replacement

// Loud Exhaust? Foul Smells? Loss of Power? //

Your vehicle’s exhaust system does more than just muffle sound — it protects you from harmful gases, maintains engine performance, and ensures you pass emissions checks. If you’re hearing excessive noise, noticing reduced fuel economy, or smelling fumes inside the cabin, you might need exhaust repair or replacement.

At General Mechanic, we offer full-service exhaust diagnostics, repair, and custom installations for

cars, vans, and performance vehicles — all with clear pricing and expert craftsmanship.

Frequetly Asked Question

Can I drive with a damaged exhaust?

While you can, it's not safe or efficient. A leaking exhaust can let toxic gases into your cabin, reduce engine performance, and damage fuel economy.

Why did my car fail MOT due to emissions?

It could be a faulty catalytic converter, leaking exhaust pipe, or malfunctioning sensors. We’ll run a full diagnostic to pinpoint the issue and fix it MOT-compliantly.

Do you offer stainless steel exhaust systems?

Yes — both off-the-shelf and fully custom. Stainless steel offers durability, corrosion resistance, and better sound tuning. Ideal for performance cars and long-term reliability.

What does a catalytic converter actually do?

It reduces harmful emissions by converting gases like carbon monoxide into less toxic compounds before they leave your tailpipe. It’s required to pass UK emissions tests.
