Stock Exhaust restrictions...
Ok, I will start by saying that I am not too sure if this counts for you non-UK guys, but have a look....
On the stock Exhaust, between the stock pipe and the back box is a small plate that narrows the tho bore down to about 1 inch... Undo the bolts, remove the plate and Bob's you fathers brother... Slightly louder and less restrictive exhaust smile.gif
I have no idea about exact gains from this, but it has to be good smile.gif

Back box = Muffler smile.gif
Ok, one of my Patent line pictures here smile.gif No pics as I have no Camera sad.gif
Right then...
CCCCCCCCCB|BMMMMMMMMM
C = Stock Centre Pipe
B = Brackets/Flanges where the Centre Pipe joins the Back Box/Muffler
M= Muffler
Anyway, see the line between the 2 sides of teh brackets? There is a Disk in there like a gasket, that resticts the availbe space from the stock pipe size down to about 1 inch....
Clearer??
As I said, it might only be on the UK cars, as I am sure someone else would have spotted it before now.... But it is there on my 2001 Tib...
