Installed the MBRP Downpipe & Exhaust
 

And it only took 6.5 hours to get r done :argh:

The downpipe to midpipe fit was a nightmare ya can only dream of & it took fully 4 hours to get installed in a fully equipped auto shop and if not for the guy helping me I'd have blown the truck up to collect the insurance :viking:

Here's the old down pipe & the new one:

Had to adjust MBRP's downpipe several times with a sawzall to get it to mate up with the midpipe and that's just plain crazzy when installing a properly engineered system. Here's one of the rings cut off the downpipe:

Then we had to adjust the midpipe several times to get it ot fit & again why is this needed on a qualiity engineered system? Here's the Midpipe's 1st cutting but it took several more adjustments to get it to fit, ya can see where the factory slits were cut deeper & then the pipe cut & notched:

Who knows maby I was wrong in expecting a plug and play system but you would think that 10 years after the OBS came out MBRP would know about how much of a pain in the azz it was and put something in the instructions saying you might need to cut the downpipe & midppipe at least.

If you look close ya can see where there is trannie frame rail contact with the midpipe & how it still needs to be "adjusted" with a hammer to clear the trannie crossmember. This is just not acceptable on a quality engineered system like the MBRP was reported to be. You can also see how close the exhaust clamp is to the transfer case & how the hangars are poking out like they were for a different truck.

To be fair, we did not have the dealers number I got the system from (a vendor here) to call and ask about install help when I was about ready to blow up the truck, but we did have MBRP's number and called & talked to a install guy who said we had the right kit and it should fit. He was of no help at all. I've since exchanged a couple e-mails with the vendor who has apologized (it's not his fault at all) and sent them up to his sales manager & I've also sent one to MBRP's generic e-mail address from there web page with no reply from them yet.

The turbo now spools up faster & she takes off/build up speed quite a bit better than with the stock system & without a doubt according to the seat of the pants dyno she runs soo much better than stock & sounds like a truck should sound so I'm happy with the performance & sound gains & once we do the final tighten/adjustment knowing the exhaust will not hit the frame & such when 4 wheeling I'll be much happier.

Yea I've put on several different systems on several different style of trucks....you always have to do the whole modify the system routine it kinda sucks at first then you start learning the tricks to installing the systems until you start modin it before you even pull the old system off.

That and the 94-97 has to be the worst truck to put and exhaust on you always wanna do this :argh: then after your done you feel like :ouch: and once your through you want to :c: and the first time you hear it run your :rocking:


It's amazing what that single exhaust upgrade will do for one of those old girls.

I tell ya I got a no name exhaust and it bolted right up no problkem

was it for a 94-97 PSD if so what brand? :tu:

Does any one kno if MBRP or any other exhaust co sells just the elbow to go over the rear axle?

Why I won't order/install another MBRP system for anyone.

my mbrp dp and exhaust went together flawlessly. fitment is perfect

Is that a 4" or 5" system?

I got the first system, a 4" Flo-Pro from WarpSpeedPerformance in Arkansas, for my '96 and it was an easy install (except the dp :argh: damn firewall).
