Focus RS exhaust with EC / EG Type-Approval


Ford’s latest landmark performance model, the new Focus RS 2.5T, has not escaped the attention of Europe’s top tuning firms and in their search for creating the ultimate tuning packages there was only one choice for the exhaust system – Milltek Sport.

Milltek has used all of its 36 years development experience and technical knowledge to produce the ultimate exhaust system for the new Ford Focus RS.

Cat-back or Full Turbo-back?

Type-304 Stainless SteelMilltek offers the exhaust in two forms, a cat-back system and a full turbo-back system. The cat-back system consists of a centre section, rear silencer assembly and dual DTM-tailpipes (see right), and the turbo-back system adds a large-bore downpipe with adjustable bracket, and a hi-flow sports catalyst (see below) - all, of course, made from the finest quality aircraft-grade Type-304 Stainless Steel.

The cat-back system can be fitted to a car in standard tune (without an ECU remap) but if you fit the full turbo-back system you will require an ECU remap to ensure a smooth and trouble-free integration with the engine management system. We also recommend that, if you have the ECU remapped, that you fit the full-turbo system to get the best out of both the exhaust and the remap.

Milltek Sport now offers a full EC-Approved 3-inch full turbo-back exhaust system including a hi-flow sports catalyst.

Astonishing Power Gains

Some of the tuners using the Milltek system have been able to obtain quite astonishing power figures. The example dyno graph (click to open PDF) from mcchip-dkr in Germany have reported a power output of 401bhp and 612NM of torque! Another tuning Focus RS specialist in the UK, SCC Performance has created the 385S - which features the Milltek system to help it achieve 385bhp and there's more to come.

3-inch Pipework for optimum flow

A 3-inch diameter pipework was chosen after extensive testing revealed that it offered the best balance between improved gas flow and reduced backpressure while maintaining low to mid-range torque, as well as enriching the five-cylinder engine sound  without producing excessive noise or droning at cruising speeds. Do not however, assume it’s a subtle sound; it endows the RS with spine-tingling tone under full acceleration, perfectly complimenting the character of the car.

Completing the transformation of the exhaust system are a pair of purposeful-looking 4.5-inch (115mm) DTM-style tailpipes which look almost OEM in appearance but hint at the new levels of performance on offer.
