What is the standard turbo fitted on this model ?

You could dump the dump possibly altogether.... but would this require a map

The standard recirc valve works fine, but if you like the dump valve sound i'd go for a Forge. I've had a couple of Baileys dumpvalves and they've all started leaking on part throttle. The Forge is much better quality and around the same price.

if you want a good dump valve then i would go for something like a turbo smart one as they look the part ,sound great (but you can turn the sound up or down) plus i have never heard a bad thing about them but to get a second hand one is quite hard, as with backbox so many out there but wrxgreens hayward and scott is very good make and very well made pipe they also sound
