I've just found a De-CAT downpipe from darkside developments for £300... I'm tempted to get one given the cost is less than half what I was anticipating. I already have a custom exhaust which has no restrictions in (mandrel bends, straight through silencers, DPF & 2nd CAT removed), so am thinking that this may make a noticeable difference to performance.

Anyone even added a downpipe de-CAT to an already customized exhaust and noticed a difference? Worth the cost of an upgrade? Obviously with a tweak of my remap if I was going to fit the downpipe...

Darkside Developments - DPF Delete Downpipe for 2.0 and 3.0 V6 TDi Engine

Oh, it's a 3.0tdi auto
