Yes, $800 is a lot, but it is cat-back (2 mufflers). The alternative was $400 for rear section only (sounds like $800/both, right?), or $1200 from Audi, for the 90q20v. Blaufurneugen (or somesuch) sells the entire 4000q rust-o-system for $395. The Scorpion is stainless. 304 alloy, whatever that means. Someone (Bob D'Amato?) likes it. Grant
