    So how much trouble is to change just the downpipe?
    I would just need to swap out the DP if/when needed.
    As the catted DP is not CARB approved and therefore not legal in my state, why bother.
    On the other hand, I like the no CEL issues and less noise.
    However the extra HP would be so nice.

    I am so undecided.

    If you have a lift I have heard it is maybe 30 miniutes. I did not have a list so I used the Ford manual and took mine out the top very easy getting the heat shield off and upper O2 probe out but you have to take the battery out and move the shifter cable bracket out of the way. nothing extreme just took a extra 15 minutes .. Putting the stock one back in for testing would be easy too as I am sure you could leave that pesky heat shield off for that little bit ..

    Can it be taken out from under the car using a jack and stands?

    Yes I used stands to get under and remove the 6 bolts that needed removing and the two that needed to be put back on as one bracket was not reused..
    From what I have been told working from the underside just takes a little patience getting the heat shield off as there is a ton of space under there. I just wanted to try Fords way to see the difference . Both ways work..

    Does the heat shield go back on with the new DP?

    Any way to install the catted DP without removing the heat shield. I think that would draw too much attention once the car needs to get smogged, especially if there is no CARB sticker for the catted dp.

    As you can see the heat shield is fitted to the stock cat. not saying that you couldn't make it work but ....

    Looks like more trouble than its worth to mod, or make a new one. Probably just have to chance it down the road.

    Quick heat shield

    If you get on the thermotec web site, you can make a good quality, conforming heat shield from three components.
    Micro louver heat shield
    Kevlar heat barrier
    Heavy duty spray adhesive

    Take a couple of layers of ace bandage and wrap around the 2JR dp to build a stand off. Then cut out some micro louver heat shield and spray adhesive on one side. Then attach the kevlar heat barrier. Then shape this composite over the dp. You will need to have a stand off of about 1/8 inch, but this composite can then be attached to brackets and to the firewall or the dp. You need to maintain an air gap. Aluminum will also work,you just have to attach the heat shield to the hot side

    Great info, thanks:)

    I am installing a really big high flow cat so will have alot of heat near all the lines there so want to ensure they do not get to hot. I hope the cat is not to big, 5" diameter case, core nearly that big, 100 cell count, I wanted it to be as free flowing as it can, just hope it gets hot enough to do its job!

    A heat shield should help it a bit besides protect things around it.

    My catted downpipe and catback are supposed to arrive today. Joe, any thoughts on heat shielding? Will I need to come up with anything? I haven't been under the car yet to see what that area looks like, but there is lots of discussion about the heat shield in another thread.
