Here are a few videos of my T409 Stainless exhaust. I almost went with the higher grade stainless, however this was cheaper and still offers the lifetime warranty, so if and when it rusts, I'll just have them replace it.

Install was a pain in the you know what. Stock brackets were very rusty and the pipes were VERY hard to get off. A few of them I had to cut slits in with a dremel just to loosen them up enough to slide the stock exhaust pipes off.

Another note, if you have a Crew Cab with the 5 foot bed, you'll have to cut one of the stainless pipes down from 31" to 23" since the bed is shorter. I was unaware and unprepaired for this, however I dug out a cutting wheel and was able to make quick work of it. If you don't wish to do that, you may line up someone else to cut it for you or look at another system.

The drivers side rear exhaust is loose and upon closer inspection, there is a stock rubber bracket that is meant to have a hanger in it to shore everything up. This is about where the last section of pipe bends upward over the Transfer case and sits almost against the bottom of the truck bed. They did not inlcude a hanger to use this bracket and their instructions fail to mention this location. I am going to make a call to MBRP and see if they just goofed and didn't realize their was a bracket there. It's very hard to see since it is in an area that doesn't get much light and the bracket is black. Because there is nothing that is mounted there, the exhaust has the tendency to sag when you give a swift tug on it, similar to a bump or something else you'd encounter on the road. For the time, I have the exhaust tied up with a heavy duty zip tie, but that's a temp fix..... this will HAVE to be fixed as I'm not one to jerry rig my truck.

First video is NOT of my truck, but of a stock exhaust.... since I have an S&B CAI installed, you can use this for reference and see if you notice the deeper tone the S&B Provides..... Enjoy!!!

I will also add that I have not driven the vehicle at all with the exhaust installed. I have a few trips planned tomorrow morning and I will certainly give a few impressions on city and highway driving.

Hey Mizzou,

Once you take your new exhaust for a test run can you report back on the interior drone? I'd like to beef up the sound on my truck, but I don't want the drone. I also don't really want to disable the MDS if I don't have to since it does give me a bit extra on my highway daily commute..

TIA!!

Much better sound from the truck. It has a deep growl to it, however it doesn't sound raspy or like a tin can when you increase the RPM. In city driving you definitely know you've changed the exhaust and it's a medium tone. I was still able to carry on normal conversations in the cab and I did not have to turn the radio up any louder, however you certainly know the exhaust is there. Highway driving was pleasant. You hear the growl as you work your way through the gears and as you drop into 8th, the sound disappears. Literally, you had to listen for the sound of the exhaust because I couldn't hear anything. Traveling back home this afternoon, I have several very small increases in the grade of the roadway. This caused the truck to downshift into 7th gear and you could certainly hear the change. Several points I found myself letting off the gas just a little so the truck would shift into 8th and the rumble would go away. I wouldn't call it a "drone" as it wasn't. The easiest way to describe it is this: When you're cruising, it's whisper quite, but if you're accelerating at all, you'll certainly know it.

MDS did kick in a few times, you hear the tone change on the exhaust, however it isn't unpleasant and I much prefer the tone now vs. the stock exhaust. It is a much deeper tone overall, even when MDS has kicked in.

Overall I am very pleased. I'm sure once I break the exhaust in, it will be very enjoyable. I picked it up right at $500 and with the $50 rebate offered through MBRP right now, I felt it was too good to pass up.

Let me know if you have any other questions and I'll try and respond as soon as possible.

MBRP has been very quick and responsive to the concerns of sagging at the stock exhaust cut outs in the rear bumper. I sent a few photos to MBRP and advised them they are missing a hanger on the driver's side exhaust outlet at the axle over pipe. I received a response within a matter of hours thanking me for the clear photos. I was informed by one of their master techs that I should undo the pipe at the rear of the exhaust, as well as at the axle over pipes. The tech wanted me to check and see if either (2) or (4) cuts had been made into the pipe where connections were made. I advised that I only had (2) cuts from the factory. The tech infomed me that sometimes an extra (2) cuts need to be made so that you can really cinche the system down. I was told that once I did this, I shouldn't have any more issues and the extra bracket/hanger would not need to be utilized.

I took my cutting wheel and made an extra two cuts on both the driver's side and passenger side pipes at both the connections at the muffler and at the axle over pipes. I reconnected the pipes and cinched them down with the provided clamps from MBRP..... all I can say is WHAT A DIFFERENCE. Night and Day from what it was..... the exhaust is rock solid, level and I have no concerns that it may sag in the future.

I cannot say how impressed I am with MBRP... they were quick to respond, quick to apologize for my problems and even offered to send me a free t-shirt and hat. I can't speak highly enough of their customer service.

Here is another video so you can hear both exhaust pipes and get a true idea of what she sounds like.
