Resonated or Non-Resonated: Picking Your Sound
Milltek splits most cat-back systems into two options, and the choice comes down to how loud you want the car day to day. A resonated system keeps a resonator in the pipework, giving a fuller but more controlled tone that stays civil at motorway speeds. Go non-resonated and that resonator is removed, which opens the exhaust note up considerably and brings a sharper edge under load, though it can introduce more drone during steady cruising. Neither is objectively better; it depends on whether you're driving the car daily or want something that announces itself.
Downpipes, GPF Options and Valve Control
For cars fitted with a particulate filter, Milltek's GPF-back and OPF-back ranges are built to work within that emissions setup rather than delete it outright, keeping the car legal while still improving flow. For those wanting more, large bore downpipes with a hi-flow sports catalyst or a full catalyst delete are available depending on how the car's used. Milltek also sells an active valve control kit for valved systems, letting you switch between quiet and loud settings from a remote rather than being locked into one mode.
Built to Last: Materials and UK Manufacturing
Every Milltek system uses aerospace grade type 304 stainless steel, chosen because it resists corrosion far better than the mild steel found on many factory systems. Combined with the UK hand finishing, that's part of why Milltek exhausts tend to outlast cheaper alternatives rather than needing replacement within a few years. Our workshop in Manchester fits Milltek systems regularly and can talk you through resonated versus non-resonated before you commit.

Frequently Asked Questions
Is Milltek a UK brand?
Yes. Milltek exhausts are designed, developed and hand-finished in the UK, rather than being mass manufactured overseas.
What is the difference between resonated and non-resonated Milltek?
Resonated systems keep a resonator for a fuller but more controlled tone. Non-resonated systems remove it, giving a louder, sharper note with more potential for drone.
Will a Milltek exhaust drone on the motorway?
It depends on the system. Non-resonated setups are more prone to drone at certain motorway speeds, while resonated systems are built to keep this in check.
Which Milltek exhaust tips are available?
Finishes vary by model but commonly include polished, Cerakote black, burnt blue titanium and brushed titanium options.
