A cat-back system replaces the pipework behind the catalytic converter. MTS Garage Services offers performance exhaust fitting Hayes drivers can rely on, with a better finish and a sound that stays within the law.
The term cat-back simply describes where the new exhaust begins and ends. Everything from the catalytic converter backwards is replaced, usually including the middle section, the silencers and the tailpipes, while the front part of the system stays as it is.
Drivers in Hayes, Southall, Uxbridge and Hounslow ask us about them for the look, the tone, or because the original system has rotted. We fit them at our Chesterfield Way garage, and we keep legal noise and emissions requirements in mind throughout.

People usually have one of three reasons. Some want a deeper or more refined sound than the standard system gives. Others want a durable replacement rather than another run of the original design, perhaps in stainless steel. And some simply like a neater rear end with better tailpipes. What we cannot do is promise a particular amount of extra power, because results depend on the car and on many other factors. A good system should be judged on fit, build quality and sound within legal limits.
Please talk to us before ordering, as a poor choice is expensive to correct. Points worth checking:
We lift the car, inspect the existing system and the hangers, and take the old pipework off in sections. The new system is test-fitted loosely first so that joints line up and nothing touches the body, subframe or suspension. Only then do we tighten everything down with new gaskets and clamps where needed. After that we start the engine, check each joint for leaks, listen for rattles and road test the car. If the original system is badly corroded we will tell you, because stubborn bolts can add time.
Call us or get in touch with your make, model, engine size and year, plus details of the system you have in mind or are considering. If you do not yet have a system, we can talk through suitable choices with you. We will explain the job, confirm what is needed and give you a clear estimate before any work begins.

It should not be if you choose a road-legal system designed for your car. Sound is subjective, so ask about the tone and volume before buying. Noise and emissions rules apply, and we will only fit systems we are confident are suitable for road use.
We do not promise gains. Any change depends on the car, the engine and the design of the system. Most drivers choose one for sound, finish and durability, and treat any other effect as a bonus rather than the reason.
Often yes, but check with us first so we can confirm it matches your model and comes with the right fittings. We can also supply a system if you prefer. Tell us what you have in mind and we will advise.
It depends on the car, how accessible the old system is and how corroded the fixings are. Many fittings are a straightforward job, but we will give you a realistic idea once we have looked at the vehicle.
Tell us about your vehicle and we will be in touch.
