M50 exhaust and sensor question....

[highoutput]

OK, Im really trying not to ask to many questions and search for everything.
However......on my M50 Im tring to fab up the exhaust from the manifold down. I was wondering if anyone else made their own Y pipe or down pipes, and had pics??

Along the same lines Im not sure about the O2 sensor...just 1? and how far back do you guys usually put them?
Best price Ive found so far is about $90,....anything better?

Thanks for help on any of this!!

i bought a y pipe from summit, for like 24$, dont both making your own, summit as good prices, and you will need a bung is what that call them, exhaust shops put those in cheap

yeah, but I have 2 exhaust manifolds to hook it up to.

Im talking right off the manifold, but I'll check out summit. I was looking at vibrant for parts to make my own.
