Exhaust Modifications & Sound Upgrades

From quiet stock to proper sport – without butchering your car

We design and install exhaust modifications that unlock a deeper, sportier tone while still being usable every day. From subtle OEM+ sound to aggressive track-style systems, we’ll talk you through backbox deletes, resonator changes, cat-back systems and tips that actually suit your car.

Exhaust upgrades that match how you actually use the car

Anyone can chop a backbox off. We prefer to build something that sounds right, lives with you day to day, and doesn’t ruin the car underneath. Before we touch a single clamp, we’ll ask how you drive, where you drive and what you want it to sound like on the motorway, not just in a car park.

Backbox & resonator changes

Ideal if you want more volume and character without completely redesigning the system.

  • Backbox deletes or performance backboxes
  • Resonator deletes for more raw sound
  • Can be combined for a more dramatic tone
  • Great starting point for hot hatches and diesels

Cat-back & custom sections

For a bigger jump in sound and flow, we can replace everything from the cat back with better pipework and silencers.

  • Mandrel bends where possible for smoother flow
  • Choice of silencer sizes to tame or unleash the note
  • Built with servicing and future changes in mind
  • Options for stainless sections where appropriate

Tailpipes & final finish

The bit everyone sees – we’ll help you pick tips that suit the bumper and the style of the car, not just “bigger”.

  • Slash cut, straight cut, twin or quad setups
  • OEM-style tips for a factory-plus look
  • Black, chrome or brushed finishes
  • Aligned properly so they don’t sit wonky

Built around your car and how you use it

We don’t fit the same setup to every car. A 1.0 hatchback, a diesel daily and a performance BMW all need different approaches if they’re going to sound good and drive well.

🔥 Hot hatch & small turbo petrol

Think Fiesta ST, Polo GTI, Abarth, small BMW/Mercedes/Audi turbo petrols. We’ll aim for crackle and character without making it sound tinny or cheap.

  • Resonator changes plus a smarter backbox setup
  • Tip upgrades that fill the bumper cut-outs properly
  • Options to keep it neighbour-friendly on cold starts

🚚 Diesel daily & vans

Want your van or diesel daily to sound less tractor, more purpose? We can clean up the note without it droning at 70mph.

  • Focus on mid-range tone, not just volume
  • Subtle visual upgrades so it still looks professional
  • Discussion around emissions and MOT implications

🏁 Performance & projects

BMW M cars, AMG, RS, project builds and track cars – we’ll happily talk about more serious changes and how they fit with your wider plans for the car.

  • Cat-back and section changes to support other mods
  • System designed with future turbo/map upgrades in mind
  • Clear advice on what’s sensible for road vs track
