I have a used Cobb Tuning Turboback exhaust (http://www.cobbtuning.com/products/?id=2308) as well as a Cobb Tuning catless uppipe that I'm taking off a 2004 Impreza WRX Wagon to replace with stock exhast (damn California Smog!). Anywho, probably looking to sell this WRX soon, and hence the exhaust. It's $1275.00 brand new, and the uppipe was around $250. Both are still as amazing in terms of performance as the day I got it; anyone know what a 4-year old used one goes for on the market?
Also, while we're on the subject - if you want 'em, make me a (realistic) offer!
