If you’re thinking about swapping your stock muffler for a louder, lighter, or more powerful exhaust, the first question on everyone’s mind is the price. Custom exhausts can range from a few hundred pounds to a few thousand, and the cost depends on a handful of clear factors. Knowing those factors helps you budget wisely and avoid surprises.
1. Material – Steel is the cheapest, while stainless steel and titanium cost more. Stainless is popular because it resists rust and looks sleek, but titanium can shave off weight and give a sharper tone at a higher price.
2. Design Type – A simple cat‑back system (removing the muffler and rear pipe) is cheaper than a full‑system upgrade that includes headers, a high‑flow catalytic converter, and a custom resonator. The more components you replace, the higher the bill.
3. Brand – Well‑known performance brands charge a premium for reputation, testing, and warranty. Lesser‑known makers can offer similar specs for less, but you might sacrifice durability or support.
4. Fitment – Cars with complex exhaust routing (tight engine bays, multiple bends) need custom‑fabricated pipes, which drive the price up. Straight‑forward models with standard bolt‑on kits stay on the lower end.
5. Installation – DIY installation saves labour costs, but you’ll need tools and time. Professional fitting guarantees proper clearance and sound level, adding roughly £100‑£300 to the total.
Start by measuring your goals. If you only want a deeper tone, a cat‑back kit made from stainless steel can cost £300‑£600 and give noticeable change. For power gains, look at exhaust headers that improve flow; a decent set runs around £500‑£900.
Shop sales and clearance sections on reputable sites. Many manufacturers discount older models when a new line launches. You can grab a high‑quality kit at 15‑20% off without losing performance.
Consider used or refurbished parts. A gently used titanium cat‑back can be half the price of a brand‑new one, and many sellers include a short warranty. Just double‑check for cracks or rust before buying.
If you’re comfortable with tools, install the kit yourself. Most cat‑back systems come with step‑by‑step instructions and require basic socket sets. Online video guides make the process even smoother. Saving on labour can cut total cost by up to 30%.
Finally, don’t overlook the exhaust tip. A cheap tip can make a loud system sound cheap. Mid‑range tips made from polished stainless add a professional finish for around £50‑£100 and are a cost‑effective way to upgrade the look.
In short, a basic custom exhaust starts at roughly £300, while a full‑system upgrade with premium materials can exceed £2,000. Pinpoint what you need, compare brands, and decide if you’ll fit it yourself or rely on a shop. With those steps, you’ll spend the right amount and end up with a sound you love and performance that matches your budget.
