Ford Cosworth Sierra RS 1988

Service Completed: Rear Section Upgrade on a Classic Icon

At MIJ Exhaust Ltd, we recently carried out a rear section upgrade on this Ford Sierra RS Cosworth (1988), carefully enhancing the exhaust system while preserving the character of this true classic.

The original rear section was replaced with a custom built back box, improving exhaust flow and delivering a deeper, more purposeful tone that suits the iconic Cosworth perfectly – without taking away from its heritage.

We often hear from classic car owners how difficult it can be to source quality replacement exhaust systems, especially for older or rare models. That’s where we come in. With fully custom fabrication, we can design and build exhaust systems tailored specifically to your vehicle, no matter how rare or unique it may be.

As with all of our work, this system was hand-fabricated in-house using high-quality T304 stainless steel and fully TIG welded, ensuring long-lasting durability, a precise fit, and a clean, professional finish.

If you own a classic and are struggling to find the right exhaust solution, rest assured – we’ve got you covered.
