In the case of the silencer modifications, we cut open the silencer and modify the internals to suit your needs, in most cases there are a series of perforated tubes, we modify these. Then standard systems on modern cars have a high stainless content, we finish off the modification with a stainless steel weld that you can not see from under the car, this allows for the system to pass an MOT, as by law the car needs to have at least one silencer in the system. We can also offer a de-cat service, again using the above methods, making it hard to tell just looking under the car. Please Contact us with your requirements and for additional pricing.
