    I'm desperately looking for some help with my MBRP exhaust installation. I use my truck for a mobile motorcycle maintenance service so thats kind of on hold until I either get this figured out or put the stocker back on...which I don't want to do since the rubber mounts were a pain to disconnect.

    I think the extension pipe (Part 1) is too long. I have the right truck (2009 4.0L EC) and the box is printed with the same thing as the instruction sheet (2.4L/4.0L EC/CC-SB). When I bolt up the extension pipe and slip the muffler on, the end of the muffler hits the rear axle and the muffler hanger on the chassis is about 6" away from the hanger on the MBRP muffler.

    I've laid out the extension pipe and muffler next to the stock exhaust and lined up the flanges. The end of the MBRP muffler is where the over-axle pipe is on the stock system.

    My extension pipe (Part 1) is about 45.2" long. The muffler is about 31" long.

    Can someone tell me if I'm just missing something simple? If someone has got an MBRP bolted up to their extended cab taco it would be awesome if you could measure the extension pipe and muffler length.

    I called AutoAnything and they transferred me to MBRP's offices in Canada. Today is Thanksgiving in Canada so their offices are closed until tomorrow. If you all see anything that would help me get the exhaust bolted back on tonight I'd be very grateful!

    Can you just cut the pipe to fit?

    work it backwards fitting up the hangers, and see where you need to cut it to fit

    I could cut the pipe, though I'd rather not. Afterall, this is a 'bolt-on' system. That is a great suggestion to bolt everything up from the tips backwards and cut the extension pipe to fit. If I can't get this resolved with MBRP on the quick I think I'll suck it up and do just that. I'm hoping they next-day air me a new extension pipe.

    No worries, i think the company has not cleared this up yet. I have the same dual exhaust as well as a couple of my friends and we all had to cut about a foot off for it to fit. We all have double cab shortbeds. We each called the company (don't remember who we talked to) but they said it should be a direct bolt in, but since we live in Hawaii we didn't want to deal with shipping issues.
    We didn't want to wait so we cut them and installed them and now have nice sounding/looking exhausts. cutting it won't affect performance or sound, just cut into that shiny stainless steel and your good. I used an air jig saw and it went through like butter. just file down the edges a little and hook her up. If you need to mess with the rubber hangers just spray with WD40 and they'll slide on and off just fine, just make sure to wipe off any excess if you get it on your pipes.
    Lastly, on the rear driver side hanger make sure you bolt the L shaped bracket to the bottom of the frame or use a couple of flat washers to make it lower so it doesn't rub up against your leaf springs as that side is a tight fit next to your spare tire. (that was a long freeken sentence).
    Any more questions just PM me. Off to the gym - aloha..

    Thanks Amo-Cat!

    I talked to an MBRP Tech this morning and he said that the exhaust is made for the longest bed configuration (Crew Cab Long Bed) and that I would need to trim the extension pipe to get this system to fit. He recommended installing from the tailpipe backwards and then measuring for the cut like Mike said.

    So, even though its not listed I guess the system will fit on a CC Long Bed and its not a true "bolt-on" for everyone else. I'll take a measurement of the extension pipe and post it later. Hopefully it will help someone else down the line.

    The MBRP exhaust is on and looking good! It was a pain to get everything lined up right.

    I cut the extension pipe to 32". I measured from the end of the flange. You can cut about 1/2" more or less and still get a good seal at the muffler so you don't need to be overly precise. An $8 hacksaw was all I needed.

    The pipe sounds great up to 3K. Deep and mellow. Above 5K and at WOT it kind of dies out and I can't tell it being all that much louder than stock. On the highway its fairly quiet and doesn't drone. Overall I'm pretty happy with it.

    Ok...last issue, I hope.

    The driver's side pipe is secure - I can't move it.

    I can move the passenger's side pipe up and down by hand. I've tightened down on the pipe clamp at the fitting as much as I can but it doesn't make much difference. The last section of pipe on the passenger side rotates at the fitting letting the end move up and down. It drops while I drive...really annoying since I can be OCD about things being symmetric when they are supposed to be.

    Anyone had this problem? Any fixes? I've thought about drilling through both pipes at the fitting and popping a rivet in there. The .01HP loss from flow obstruction would be worth it...
