Hi folks, I'm currently looking for a set of DPs for my 2009 N54 135i (UK model) and was originally looking at a set sold in the UK, but the manufacturer is currently making a "V2" version with a cast elbow at the turbo outlet, but they're downsizing the piping to 70mm as they say it apparently will help torque on these cars without causing any drop in power vs 3" tubing.

I'm just wondering what the collective knowledge on this was - whether that sounds right, or if it's just a case of bigger tubing = better?

Thanks

Russ
