The only bad thing i`ve heard about them is that the welds are a bit tatty.
A decat does give you more power and torque as the cat has a shite load of honeycomb type cells in it which is a big power zapper,in fact I read somewhere that it can be upto 20 horsepower ( dyno proven )..i`ve known people who had de=cats and had there car`s dyno`d before and after and they all had an increase in power ofter the de-cat was fitted. :kaffeetrinker_2:markderby said:doesnt give u any more BHP ... Doesnt give u more Torq ...
what it does do ....
makes the turbo spool up faster ( less lag )
makes the throttle response alot nicer and smoother
alowes the engine to rev more freely
