I made mine just the way dragrcr97 made his, not as nicely welded as his but good enough. It was the only way I could fit 1 7/8" tubes from the W8 heads in a stock front suspension.
2" pipes could be made to work in the same location, but I bet you it will be a tight fit...

Just remember that if your going to use different heads later on it might not be as easy as just cutting the flanges and weld on new ones.
The W5,8,9's have higher exhaust ports than standard heads. W5's are .400" higher than W2's and W8 LeMans and W9RP are located higher than that (if I remember what Ryan said correctly).
Just something to keep in mind when doing them
