[Jan]

Can anyone on here confirm this?

Thanks

Think the downpipe angle is different and i dont think a 16v cat will fit a Williams.

[Caramelx]

A 16V Cat will NOT fit a williams, From what i remember when we changed them on the cars they have different angles.

The Flange joints are different, on both ends of the de-cat pipe for the 16V they are the same, on the Willy, one end is rotated round 45 degrees....if that makes sense.

[Jan]

have you read the post? the magnex one has one floating flange which means it might fit? no-one seems sure tho

[Irish Nut]

They are both the same length from what i have seen, but if it does have a rotating flange joint then it should fit both the Willy and 16V no probs! :D

right, just to settle this. BB tuning have a twisting decat like the one described. It fits both a valver and a Williams as the mounting is exactly the same from the downpipe and the other end on the williams is 45 degrees as opposed to 90. IT WILL DEFFO FIT if it twists. I have given a twisting decat to my mate and it went on his valver no problem.

Yep as long as its a rotating or floating flange one end it'll fit no probs.

If the end is floating it will deffo fit, spent all of last weekend under my valver and summys williams playing about fitting the exhaust and various other things

only diffrence is the flange on the end. Summy's manifold on the williams is now a valver one with a valver down pipe, he had to get a valver decat as the williams cat woudlnt lineup, now it all fits perfectly


when you look at a williams down pipe the bolts are virtical i.e one at top of the pipe and one at the bottom but the valver the bolts are horizontal so looking at the pipe the bolts are left and right this is why the end wont fit both unless its floating but from the back of the car the mounting positions are identical both on the valver and williams, making the exhausts interchangerable from cat back
