5 Best Muffler Shops in London (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Talise Sterling, Goods and Shopping · ✓ Data verified July 2026 · 8 min read

A rattling exhaust or a failed MOT emissions check does not wait for a convenient weekend. London's muffler shops have logged 3,390 reviews between them, and the gap between the busiest and quietest name here is enormous: over 1,400 reviews at the top against 184 at the bottom, which says more about how long a shop has been trusted than any single star rating does.

Short answer: Mr Exhaust in Reigate holds a perfect 5.0 across 655 reviews, the strongest combination of rating and volume on this page. Madhouse Tyres has the most reviews overall at 1,426, though its 4.5 rating trails the pack. FWR rates 4.8 across 747 reviews but is primarily a motorcycle specialist that also handles car tyres and MOTs, worth knowing before you book.

Who to call for exhaust and muffler work

Madhouse Tyres logo
#1 Overall🕑 Open 7 days

Madhouse Tyres

4.51,426 Google reviews

Madhouse Tyres is a part-worn tyre specialist in South London, describing itself as carrying the largest selection of high-quality part-worn tyres in London and the South East, alongside new tyres from premium and budget brands. It's primarily a tyre shop rather than a dedicated muffler specialist, but it's the most-reviewed name on this page by a wide margin.

What people praise

  • Alloy refurbishment praised for bringing wheels back to factory condition
  • Staff called knowledgeable and able to handle non-standard tyre sizes, including classic cars
  • Reviewers describe the service as quick and reasonably priced

Worth knowing

  • Rating trails the rest of the page, and the review distribution shows a real minority of one-star experiences alongside the many five-star ones

FWR

4.8747 Google reviews

FWR is a motorbike parts and tyre shop in London, doubling as a DVSA-authorised MOT test centre for motorcycles and scooters.

  • Staff repeatedly praised by name for reliability across brake, tyre and general servicing

Our take: Strong numbers, but this is the one entry here worth a flag: FWR's business is built around motorcycles, not car mufflers, even though it shares the auto-services category. Call ahead if your job is a car exhaust.

Kwik Fit London Chelsea is part of the national Kwik Fit chain, covering tyres, brakes, air conditioning, MOT testing and wheel alignment out of its Sloane Avenue branch.

Watch: 5 Best Muffler Shops in London (2026)

How we score these shops

Rating is the live Google average for each shop. Review volume measures how many customers have left a review, ranked against the others on this page. Confidence blends rating with volume, so Mr Exhaust’s perfect score across 655 reviews carries more weight than a perfect score built on a handful. Recency tracks how recently people are still reviewing. No shop can pay to change these numbers.

How much does muffler or exhaust work cost in London? (2026)

None of the shops on this page publish fixed muffler or exhaust repair rates, and prices vary heavily by vehicle make, whether it’s a standard repair or custom fabrication, and how much of the system needs replacing. One reviewer at Flowtech Exhausts mentioned a repair costing around £35, which shows how wide the range can run between a quick fix and a full custom job. Get a quote for your specific vehicle rather than relying on a general figure.

Serving London and the wider South East

These five shops span central and outer London plus the surrounding commuter belt, from Sloane Avenue in Chelsea to Dagenham in the east and Reigate just south of the M25. If you’re searching for a muffler shop near me in London, the two true exhaust specialists here, Mr Exhaust and Flowtech, are both just outside the North and South Circular, so factor in the drive against how urgent the repair is.

What to ask before you book exhaust work

  • Do you specialise in car exhausts, or is this mainly a tyre, motorcycle, or general garage?
  • Is this a standard swap or custom fabrication, and how does the price differ?
  • Do you offer a warranty on welded repairs, and for how long?
  • Can you fit me in the same day for a failed emissions test before my MOT expires?
  • Do you work on my specific make, especially if it’s an older or less common vehicle?

Frequently asked questions

Are these rankings paid?

No. Rankings come from public Google data. A business can pay to be a Featured Partner (badge and top placement), but that never changes another business’s score or position.

Are all of these shops muffler or exhaust specialists?

No. Mr Exhaust and Flowtech Exhausts are true exhaust specialists. Madhouse Tyres and Kwik Fit are general tyre and fast-fit garages that can handle exhaust-related MOT work, and FWR is primarily a motorcycle shop. We’ve flagged each one honestly so you can pick the right fit for your job.

How did you choose these shops?

We pulled real Google Business Profile data for auto shops in London handling exhaust, muffler and related work, then ranked them by rating, review volume, and recency of reviews.

How often is this updated?

This page reflects data verified in July 2026. Ratings and review counts shift over time, so treat the specific figures as a snapshot rather than a permanent score.

Is a loud exhaust an MOT failure in London?

Excessive noise or a damaged exhaust can fail an MOT emissions or noise check. Several shops on this page, including FWR and Flowtech, offer MOT testing alongside repair work, so you can often get both done at the same visit.

The bottom line

Mr Exhaust is the safe default if your job is genuinely exhaust or muffler work: a perfect rating on real volume from a shop that does nothing else. If you’d rather bundle tyres, an MOT and general servicing in one visit, Kwik Fit or Madhouse Tyres cover that ground, just don’t expect the same specialist depth on a muffler job.
