Let’s face it, for many of us, the sound of our car is just as important as how it looks or performs. A whisper-quiet exhaust can leave you feeling a little… underwhelmed. If you’re craving a richer, more resonant tone, you’re in the right place. We’re diving into the world of exhaust upgrades, exploring how to transform your car’s sound from a timid purr to a confident roar.
Why upgrade for sound?
Beyond the sheer pleasure of a satisfying exhaust note, upgrades can also release some serious potential from the performance of your car. Here we talk you though some of the best exhaust upgrades to make if you are taking your first steps into upgrading your exhaust.
Back Box Upgrades: Your First Step to a Sportier Sound
A Back Box is likely to be your first stop when looking to upgrade your exhaust. Simply put, a performance back box replaces the existing rear silencer on your car. Whist replacing your back box offers very limited performance upgrades, what it does offer and why you are probably reading this blog, is it will provide a louder, sportier, more aggressive sound to your car.
There are several options on the market to achieve this, but we believe in working with the most renowned exhaust brands out there, to be able to bring you a comprehensive range of the best direct fit options for your vehicle when looking to upgrade, all offering slightly different characteristics to achieve an enhanced sound. High quality manufacturing from the highest-grade steels available, these upgrades are built to last. Many with customisable exhaust tips for that personal touch too 👌


Cat-Back Exhausts: The Sweet Spot for Performance and Sound
The cat-back exhaust system is often the go-to upgrade for a reason. It’s the perfect middle ground – enough change to make a real difference to the sound and now performance, but without any needs for Remaps or removal of catalytic converters or GPF/DPF Filters, more on these in a deeper delve into exhausts systems here.
When you invest in a cat-back system, you’ll typically get the centre pipework (sometimes with a silencer, depending on the manufacturer and model), and the rear section, including silencers and those all-important tailpipes, sometimes offering options here to personalise the look of your exhaust.
It’s all about maximising flow and minimising restrictions and by doing so you will increase the power of your vehicle and give your car that all important, sportier sound!
