A performance exhaust system is one of the easiest ways to increase your cars performance. An aftermarket exhaust removes restrictions which reduces back pressure and allows exhaust gasses to escape more easily. This in turn allows air and fuel to be drawn into the engine more effectively. Replacing an OEM exhaust with one that is much less restrictive is often a first step in tuning your engine. Aside from the increased horsepower a new exhaust can often save a considerable amount of weight, further improving your car’s performance. If you’re looking for a new full exhaust system, a replacement back box, new tail trims, or even a less restrictive exhaust manifold then you’ve come to the right place. Our huge range of exhaust parts and exhaust systems from all the big brands means there’s something for every car and every driver. We’ve got a great selection of cat back systems and sports catalysts, or if you’re heading to the track we have cat replacement pipes or full systems without catalytic converters. If you can’t find something to suit or if you want something completely different then a custom Powerflow stainless steel exhaust could be the answer – a bespoke exhaust system fabricated and fitted here at Demon Tweeks while you wait.
