Even though the new Focus RS has more doors than your average hotel, there can’t be anyone on the planet who doesn’t love it, right?

It’s certainly set to become a modifying icon and, even though they’ve been on the streets for less than a year, the parts are now coming thick and fast!

That said, what’s really interesting about this awesome-quality, axle-back exhaust from Ford tuning maestros Mountune, is that slapping it on your brand new motor doesn’t affect your manufacturer warranty at all.

Yes, you get a sweet hike in power, a 28-percent weight saving over the original item and a vastly improved soundtrack. It even includes a new valve and motor assembly for those who like playing with the OEM adjustable silencing thingy.

But the bods at your local Ford dealer can’t say a word about you ripping out their stock system if, as it turns out, your heavy right foot doesn’t agree with the engine. You’d be silly not to.
