Frequently Asked Questions

Which exhaust brands do you specialise in?

We are specialists in fitting Quicksilver, Milltek, Capristo, and Scorpion systems, but we can also work with other premium exhaust manufacturers.

Do you supply as well as fit exhaust systems?

Yes — we can source genuine systems from the brands we work with, or we can fit a system you’ve already purchased.

Are these exhaust systems road legal in the UK?

Yes — many Milltek, Scorpion, and Quicksilver systems are designed to be road legal, while Capristo and track-focused systems may be intended for off-road use. We’ll advise you on the best option.

Do you install valvetronic or switchable exhaust systems?

Absolutely. We fit valve-controlled systems that let you switch between quiet comfort and an aggressive sports tone at the push of a button.

What types of cars do you work on?

We specialise in sports cars, supercars, and prestige vehicles, including Ferrari, Lamborghini, Porsche, BMW M, Audi RS, and Mercedes AMG models.

How long does a full exhaust system installation take?

It depends on the system and the car. Cat-back installations can often be completed in a day, while turbo-back or full bespoke systems may require more time.
