cut the flange off the top of the dp. if you're lucky it will fall out. is the new dp a stock rep that will bolt up to a stock exhaust?

Just take a sawzall and cut the cobra head right next to the turbo outlet. Then unbolt it down under the truck and it should slide right out the bottom. Then you need to make room for the new pipe, you will see the difference between the round 3" downpipe and flat stock downpipe. You would help yourself immensely if you go and get a portapower to maneuver the firewall. If not, a baseball bat or crowbar will do the trick with some elbow grease... Put the top half of your new downpipe down from the top and you will see which section of the firewall needs to be moved. Then move it until you can slide the downpipe in and have a good little bit of clearance.

It's really not that bad, people just get frustrated when it doesn't slide right in... Sucks when you buy an aftermarket part that doesn't just bolt in...Lol

and make sure you have adequate clearance, take it from a guy who knows. when that downpipe hits the firewall, it's like your inside of a drum being beaten by a drummer of a death metal band

oh come on, it's not THAT bad... re,ember that when you think you have enough clearance, go a little bit more. incase the fire wall wants to move back it won't go to far...
