Magnaflo 4" down-pipe Installation Problem

[twoicebergs]

As it says, I am finally putting the 4" down-pipe in. The problem I am having is it won't make it between the up-pipe and the body in any position without catching or running into the trans cooler lines. Before I pull the transmission cooler lines to see if that gives me enough extra room to maneuver, has anyone else come across a similar problem? It is the Magnaflow 17992 SS kit.

If I remove the lines and I still need to flex the firewall, I won't be a happy camper!

IIRC, on my old truck it went in with just a bit of grief due to the leaf springs and swaybar, but I didn't have to beat the crap out of it. Hopefully I will get an answer before I pull the lines and maybe the dip-stick tube.

I did a little more searching and some are smiling and others are cursing. There are a lot of 4 and 5' systems with 3.5" down-pipes. I wonder why! It seems in my case I will have to take off the transmission cooler lines (1 or 2) and maybe that is it. If that doesn't work it is the bash and smash. I'll let you know what I finally had to do. So much for an easy install. The rest of it only took about 1/2hr when I first installed it 6 months ago.

In case you are wondering how to separate the holding pins from the rubber supports, just use WD40. It makes it a breeze.

My magnaflow 4" was tight, tight enough I had to use a dead blow hammer to get the flange up thru. Once it's in though it's fine, no harm no foul and I love the kit.

same deal here with my 05.

So it wasn't as bad as it could have been. I just had to take the one tube off the transmission and push it to the side. It still required a good push that ripped the insulation a bit to get it in place. I removed the kitty as well.

It no fit.


It fit.

I actually can't remember if I had to move that line BUT now that you mention it something seems familar
