I'm going after work tomorrow to weld some flanges on my buschur HF cat so that i can use it with my current downpipe/catback setup. I won't be able to measure the angle of the flanges or the length of the stock cat before i get to the machine shop but i know that i need to make the HFC bolt up in the same position/length as the stock cat.

my request... if anyone has a stock cat laying around...could you please measure the length of the cat from the very ends of the flanges on both sides? in addition, can you measure the angles of the flanges with respect to the cat layed out on the ground? basically i need to know the angular offset (clockwise or counter-clockwise) of the cat-back side flange and the downpipe side flange.


If you are willing, please measure with respect to this crudely drawn diagram. and while looking straight on at the flange. Take note of the side (DP or Midpipe) and the +/- (clockwise/counter) angle.

Thanks very much for any help you can provide me. I'll make this into a how-to or some other sort of persistent infromational thread for others attempting the same (albeit ridiculous) customization when it's all said and done.

Length of the cat, including full width of flanges ___________
Angular offset on midpipe side +/- _______ Degrees
Angular offset on downpipe side +/- _______ Degrees

thanks again, and again.

 

bump. thanks for looking, and thanks in advance to anyone who can help me out.
