Has anyone installed a MBRP Downpipe for a LB7? How hard was it? Do you have to drop the tranny? The shop where my truck is at seems to be having a hard time breaking the bolts loose, just trying to see if I can get some info to help them out a bit.

yeah if i ever do it to my truck i wont even bother...ill prob smash the windshield and break everything in my shop lmao
Soak the bolts. Get it hot. Is use a matco 1/2" drive flex head ratchet with a 17" handle. I do them all from the top but you can access some from the ps fender well too.
x2. i wound up taking a 14mm wrench and cuttin the open end off, then put a long extention on a socket that jsut fit over the 14mm wrench. worked really well. they are jsut a bitch though, jsut gotta keep workin at it
Rick Lance makes nice stuff. But he did not make the original. TTS was the first company to offer an aftermarket downpipe option for the LB7.
I built mine but its similar to the RDL.100* egt drop and feels more responsive but I haven't strapped it down to know for sure.
well the shop never got it on....
so now I'm stuck with dealing with it. Hopefully I'll find someone local who can help me and we'll get the job done. Propane torch anyone?
You can do it yourself, they are not to bad to get out. I used a little pb blaster for a couple days and drove my pickup to help work it in there, and then built a tool that I found on DP and it worked like a charm for the top three bolts, if you need a pic let me konw, and the two 14mm nuts I got loose with a box end wrench, and the center bottom bolt I used a 3" 3/8" extension with a flex head ratchet and a GOOD 12 point socket to get it off. They are tight and I've heard horror stories, but you can do it man. I pulled my downpipe out through the top driver side, and just unbolted the tranny dipstick, but didn't remove, I would say total time to get one out was maybe and hour and half. but good luck man they are tight!
This is what I made a few years ago. Basically two crap sockets welded to a half of a ratchet and a piece of rod long enough so you can get a breaker bar on it and out from under the firewall. Not the prettiest thing but pulls the top three bolts out no problem. Also a word of advice get some studs and lockwashers and nuts so if you ever have to take it back off it will be a breeze. If you cant make a tool and you want to borrow mine Ill send it your way you just pay the shipping.
