Cat-back or Full Turbo-back?

Milltek 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 and the turbo-back system adds a large-bore downpipe with adjustable bracket, and a hi-flow sports catalyst. 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.

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.
