Hi all,

So I got the stainless steel MBRP Offroad exhaust as my Christmas present and just got back from visiting the family. After installing the exhaust and driving about 400 miles on it I can give a nice detailed description of the install process and the results.

First of all as many people have said far and away the hardest part of the install is removing the stock exhaust and getting the stock hangers off. BUT after about a half an hour of monkeying around with screwdrivers and WD-40 as many suggested my dad came up with a genius solution to everyone's problems of getting the stock hangers off: USE A SMALL FLAT CROWBAR TO PRY THE RUBBER ISOLATORS OFF (like the one pictured below)



Once we thought to do that it literally took about 5 minutes to get ALL FOUR hangers off!! I hope this can help people looking to do this upgrade in the future...

So following getting the stock exhaust off the new exhaust went on perfectly and easily the first time. Just make sure (as noted before) to align the gap of the band clamps with the cuts in the ends of the pipe section. With just aligning the clamps right and a decent amount of elbow grease with a ratchet the exhaust is on there solid as a rock (no need for an impact wrench).

Since the install I have driven about 400 miles of mixed back roads and highway and can give a detailed description of what I have noticed. First of all the power boost is very noticeable. I have not redlined the engine with it yet but have noticed a pleasant boost in low-end torque. On the back roads it pulls much harder between shifts, even at part throttle, with only revving the engine up to between 2500 and 3000 RPMs before shifting. The power boost on the highway is very nice: places when I would lose speed, have to downshift, or would just barely be able to maintain speed now with the new exhaust it easily maintains speed at part throttle and accelerates at full throttle in 6th gear (even up decently steep hills).

Finally as for the sound it is literally perfect for what I wanted! It is just enough that at idle and low-throttle it is VERY deep like and barely louder than stock (which should also keep the neighbors happy). At full throttle and the engine at 2000 RPMs it is still a very deep tone and the volume in the cabin is about equal to between 10 and 12 on the radio (of course quieter at lower RPMs and a wee bit louder at higher RPMs). With my wife sleeping in the JK on the way back tonight I had the radio volume set to 12 and could hear both the music and exhaust perfectly clearly with the radio set to 12 and cruising at 70 mph between no and full throttle depending on the slope of the highway in 6th gear at 2000 RPMs.

I hope that this helps push anyone considering this upgrade over the edge. Also I would like to take this post as an opportunity to thank MBRP for making a top notch product!!

 

Nice write up! I also have this exhaust, about 4 months now, and it really was a great purchase and easy install.

 

Congrats to you bud...I also got the MBRP exhaust last August...
Awesome product...Nice write up by the way...

 

Thanks, the crowbar worked so well that I would say it is well worth the cost of going out and buying it specially for the install. I will see whether I can take some pictures and video this afternoon of the final install

 

In the stock location the muffler has a heat shield between it and the body. In the relocated position does the MBRP Offroad kit include some type of shield or insulation? Does heat from the muffler in the new location cause any problems? Looking to pull the trigger on this upgrade and want to make sure I am not walking into a problem.

 

ok..my muffler is in my garage waiting to be put on..i do have a sorta dumb install(or in this case, removal question):

can i just take a sawzall to the old muffler to get it off? am i missing something obvious as to why not?
