I just purchased a magnaflow cat back for my 94 z and was wondering roughly how long it would take me and my dad to install. He is pretty mechanically so I figure it won't take to long. Also I wanted to let you guys know that there were some specials on ebay (don't know if they are still going...do a seacrch) for these exhausts. I got my shipped to my door for $250! I know you could get them for 285, but 250, I couldn't pass it up. Anyways, thanks in advance for the info.

Including jacking up the car, removing the old system and bolting up the new one - I'd say about an hour and a half working comfortably. If you guys cranked it out probably half hour.
