does any one know the size and length of bolts

Wish You had Asked me this Question last Fall,,, as it has been a year since this part was replaced. Think the bolts were approx. 4 inches ? Just look at the photo of the bolts and the nuts... almost a 4 to 1 ratio... After a Year the extenr ion pipes between the muffler and the Cat Converter Rotted out. Now I have to replace them again ! Which will cost about another $ 50.00 while the tailpipe will cost $ 39.95 Go figure.,,

Does it fit 2012 Fiat 500 exhaust manifold?

look up the part number for your type of exhust manifold. my car was a 1997 chevy blazer ls 4.3 so check to make sure it fit

Are these fitable on a Vulcan 3L V6?

This is a universal setup, it should fit just about any flange type. Measure your bolts and compare them to these. As for absolutely fitting anything, it isn't possible for one set to fit anything. Take the measurements and then compare until you find what will do the job. Hope that helped.
