To celebrate the milestone that is our 400th issue, Euro tuning specialists, Direnza, have just launched a whole new range of free-flowing race manifolds.

OK, so that may be a bit of whopper, but the important thing here is that they’ve not only included a whole load of fitments that you won’t find anywhere else but, rather kindly, they’ve kept the prices down too!

The one pictured is for a Mk6 Astra VXR, but there’s also plenty of other applications ready, and even more on their way.

What they all have in common is that they’re constructed from the highest quality 3mm-thick, T304 stainless steel, and guaranteed to free up the immense restrictions caused by factory manifoldsfor more power and far better throttle response. Bonza!

Priced from £249
