Williams Exhaust - 16v exhaust. Differences

[cliolord]

As most of you know, I have turned my 16v into a hybrid which is the first time I have done this. I didn't realise that the downpipe on the williams is different to the 16v. I tried fitting the williams downpipe onto my mongoose exhaust and decat today and it doesnt match up properly. Do the williams use different cat's aswell or anything else different?

yup the williams flange is different, at 45 degrees but back end of the cat and back its all the same :D

i thought i posted to watch out for this in the other thread :D

i mean 90 degrees oopz :S

lol i didnt notice a post about this. I have an adjustable type de-cat or maybe a "bodge" decat, which is actually an amazing idea. I can swivel the flange 360* then clamp it up again so that wasnt a problem. It was the male end that came out the end of the downpipe which the decat fits onto...It was far too big. So i turned the decat around and am running it back to front at the moment but I want to get it right. Hate things being "bodged" ;)

I will ask if anyone has a decat and/or a cat for the williams now lol

[Allan]

im sure it will be fine :D

after all a decat is just some pipe, nothing in it !

Williams also has an extra mount for the centre box :D
