The package came with downpipes, incl manifold flanges, and resonators (could be ordered without them as well). The hangers and clamps have to be purchased separately. The rearmost hangers are the hardest ones to come by, if you want originality. They are reproduced but are very expensive, so I opted for a generic type (works great).
The downpipes are 2", and I'm also running standard exhaust logs. Sounds great to me, but then again it's all about personal taste.
Update: Just checked at www.thepartsplaceinc.com, and the aluminized system w/resonators costs $349, while the stainless steel type is $999. Seems to include all hangers and clamps too.
