Mongoose Exhausts has been established as a brand of aftermarket performance exhausts since 1994, and are one of the most highly regarded stainless steel exhaust manufacturers in the UK offering an expanding range of exceptionally high quality performance enhancing sports exhaust systems for many marques of cars.

Every Mongoose Exhaust component, be it a down pipe, a back box, or a full exhaust system is designed on the car it is meant to fit – that way we can guarantee a perfect fit every time.

Not only will your Mongoose Exhaust be a perfect fit, it will also be beautifully finished and brilliantly engineered, giving you the best performance, look and sound possible, without breaking the bank.

All Mongoose Exhausts are made in the UK from T304 aerospace grade stainless steel, bent using the finest mandrel bending machines and welded by experienced and enthusiastic staff to exacting standards. Don’t buy an inferior quality exhaust, buy a Mongoose Exhaust.

The Mongoose performance stainless steel exhaust range covers many of the most popular European cars and also many Japanese models.

High quality T304 stainless steel aftermarket performance exhausts with lifetime guarantee for many different vehicles. All Mongoose Exhaust systems offer excellent fit, exceptional build quality, a performance increase, great style and the ultimate in sound.


Change your restrictive OE downpipe section, to a Mongoose Exhausts high flow downpipe to increase the power and performance of your vehicle.


For those seeking the ultimate power increase for motorsport or track days, our cat replacement pipes reign supreme ensuring optimum performance and sound.
Selected models of Mongoose Exhausts cat replacement pipes include a de-restricted straight through silencer where it necessary to maintain sound quality.

** Please note – some vehicles fitted with OE catalytic converters will not pass an MOT if removed and replaced with a Mongoose Exhausts cat replacement pipe**


If you want to increase the power of your road car and keep it legal and MOT compliant, then fit one of our sports catalytic converters. These catalytic converters are much higher flowing than the OE part fitted to your vehicle already and will make a difference to the way your car performs and drives.


Not only do Mongoose Exhausts offer a range of high quality great fit exhaust systems, they also do a range of equal quality rear boxes to give you that perfect Mongoose Exhausts sound and style.
