oh right sweet cheers buddie

We get cars in at work all the time with Powerflow systems and i ahev to say that i was shocked at the condition of teh welds etc etc sometimes.
Very 'snottery' and alot of them are rusted to hell.
Plus they use a stainless silencer with mild steel piping in between ??? Stupid!
Saying that, ive had a few backboxes and they seem in good condition.
Must depend on where you get it done....

As per all the other comments, the quality varies from dealer to dealer. I've had my Powerflow backbox done about 3 years ago and its still 100% now, no rust anywhere..

as above
