It’s time to bring the noise, with some help from Milltek Sport…

For me, a V8 should sound like a V8. But, the exhaust system on the RS4 B7 is a pretty understated affair. In fact, until you stick your foot to the floor and the exhaust valves open, there’s not much noise at all. Don’t get me wrong, it sounds superb at times, but it kind of lacks that sense of occasion you expect when you hit the push start on a V8. So a new exhaust has been high up on my list of first mods.

There are quite a few available options Audi RS4 B7 exhausts, but after a lot of research and plenty of recommendations on the Audi forums it seemed pretty clear the best choice for me was going to be a Milltek Sport system.

It’s a brand I trust. They’ve been around for 35 years now and I’ve seen enough of their systems to know they are built to last. And they sound damn amazing too!

As with most of their Audi RS range there’s a choice of valved or non-valved systems and resonated or non-resonated (quite a bit louder). Obviously I went for the non-resonated. But I decided to have a valved system, because it’s nice to have the choice to run something a bit quieter when you’re stuck in traffic and not in sport mode.

Anyway, without further ado I got it ordered and amazingly it was with me the next day. Later that week I was at custom vehicle specialists Down & Out getting it fitted.

Admittedly it’s been a while since I’ve had a bolt-on system (as my last few exhausts have been custom made), but I couldn’t believe how quick the fitting took. It was under two hours!

Obviously having a ramp, no seized bolts and someone like Chris Hazell doing the majority of work helped. But what really helped was just how well fabricated the Milltek exhaust system was. It wasn’t just inch-perfect, it was millimetre-perfect. And, it came with every single part you needed, even the brace bar, which was a nice touch.

As you can see from the photos, it looks magnificent and the stealthy satin-sheen black tips definitely give the rear end a tougher look.

But how does it sound? Well… let’s just say I’ve not stopped smiling in the RS4 since the Milltek has been fitted. The burble on the start of that V8 purr as I cruise along the road and that deep throaty blip as I plant the accelerator… it’s perfect. It’s not too loud, not too ASBO like. Nope it’s just right!

And from the first drive you can already tell it’s definitely added some extra power. The car just feels less restricted as you go through the gears.
