Flanges

[RedRocket1]

So im planning on making a pipe to replace the cat...and im gonna make it outta stainless so im wondering if anyone knows all the exact dimensions of the flanges and pitches of the holes on the flanges on the cat.
Also the length of the cat as i need to make it 2 inch shorter.
I would check but i cant be arsed tomorrow and im sure one of you know it.
