Milltek Exhaust Guide: Everything You’ll Need To Know Before Buying Milltek

Milltek Resonated or Non-Resonated? Titanium or Carbon Fibre? Burnt or Polished?

Tuned at JF Automotive, MaidstoneSeptember 2019

The two choices that decide what a Milltek system sounds like are whether it is resonated and which tip you pick. A resonated system keeps a chamber that cancels certain frequencies, so it still has a note but drones far less at a constant motorway speed. A non-resonated system replaces the front silencer with a straight delete pipe: louder, with more drone under load. Tips come in Cerakote Black, Polished, Brushed Titanium, Burnt Titanium and Carbon Fibre. We supply every Milltek system, fit them here in Maidstone alongside a remap, or ship direct to you or your garage.

Many customers email us every day asking what exhaust is most suitable for their car. For this reason, we have written this short guide that covers everything you need to know before deciding the right part for the job. More specifically, in this case study we are focusing on the Milltek exhaust system options, however many points in this article will be relevant when considering other aftermarket exhaust manufacturers. If you’d like to find out more about Milltek, check out their website.

The Milltek Sound

There are many factors that determine what your stainless steel exhaust will sound like. Luckily for you, Milltek have made this decision much easier by offering the option for a resonating silencer on your system. A resonated system contains a chamber specifically designed so that when the sound made by the engine enters, the waves bounce around in the chamber, cancelling out certain frequencies of sound. This results in a cleaner and quieter sound leaving the end of the exhaust. Although your exhaust will be quiet, it will still produce a nice note. The biggest advantage of the resonated system is that there will be much less ‘droning’ when driving at constant high speeds, i.e. on the motorway. We would recommend a resonated system to someone who wants to have a good exhaust note but doesn’t want the droning sound under load!

Res

The parallel of this is an exhaust system without a silencer. A non-resonated exhaust like this contains almost all of the same pipes, except the front silencer. In its place is a front silencer delete pipe which simply carries the gases and sound waves straight into the cat. As you can imagine, this makes the exhaust a lot louder as there is no resonating chamber as we previously mentioned. The true downside of this set up is the droning sound that is produced when driving at high speeds. This can put many people off a non-resonated exhaust, but some people do prefer the louder tone when there is no silencer.

NonRes

Now for the Milltek tip

The tip of the exhaust seems quite self explanatory. The exhaust tip is the end of the exhaust that you can (usually) see from the rear of the car. Milltek offer 5 unique exhaust tip options: Cerakote Black, Polished, Brushed Titanium, Burnt Titanium and Carbon Fibre. Tips vary in price due to the material used, but all of them are of good quality and are easy to keep clean.

 Where to buy your Milltek exhaust system

Questions we get asked

Should I buy a resonated or non-resonated Milltek?

Resonated if you drive motorway miles or use the car every day: you still get the note without the drone that wears people down at a constant speed. Non-resonated if you want it as loud as the system goes and you accept the drone under load. It is the single biggest decision on the whole order.

What is drone and why does it matter?

A resonance at a particular engine speed, usually somewhere in the range you sit at on a motorway, that makes the cabin boom. It is the most common regret with a non-resonated system and it cannot be tuned out afterwards without changing the exhaust.

Which Milltek exhaust tips are available?

Cerakote Black, Polished, Brushed Titanium, Burnt Titanium and Carbon Fibre. Price varies with the material; all five are good quality and easy to keep clean. The tip changes the look, not the sound.

Are Milltek exhausts any good?

They are one of the better mass-produced systems: stainless throughout, properly mandrel bent, and the fitment is right first time on the cars they list, which is not something you can say for the cheap systems. We fit them because we do not want cars back for leaks and rattles.

Will a Milltek exhaust add power on its own?

Very little on a standard car. Exhausts pay for themselves when the map is written around them, or on a turbocharged car where a turbo-back system with a sports cat lifts what a Stage 2 file can safely do. Fit the exhaust and remap together and you get the whole gain, not half of it.

Can you supply and fit it, or ship it to me?

Both. We stock the full Milltek range, and we can fit it here in Maidstone at the same time as your remap, which saves a second visit. If you would rather fit it yourself or use your own garage, we will ship it direct.
