The 6.4 HD Hemi Thread

[Gumpsta]

Here are before and after pics of the mufflex, I just left the resonator off, I think it sounds good, so didn't even try with it on. I will probably get a turn down, I like the clean look with no pipe sticking out anywhere.

Sorry for all the replies. I can't figure out how to attach more than one picture per reply.

Here is YouTube clip. Not sure why it's so quiet.

Install looks good, so the mufflex is really only designed to just replace the factory muffler. I wonder how easy it will be to fine 3.5 turn downs to match up.

Yes, it is a bolt in replacement for the factory muffler. Took less than an hour to do. Any exhaust shop should have a turn down tip, and would take all of about 5 minutes to tack on.

Gumpsta, is there any drone while cruising?

What he said.. like " 55-70" cruise on the hwy when mds kicks on

 

[Gumpsta]

I haven't had it out on the highway yet, I only live about a mile from my shop, so it could be awhile before I get the MDS to come on. Cruising at 40-50 with the engine between 1500-2000 RPMS you can definitely tell it has an aftermarket exhaust, but nothing annoying. I'm really happy with how it sounds so far, if you want to hear it, just keep the pedal to the floor, and it will roar. If you drive like a normal person, it has a good tone, but not too loud.

No drone when mds is active. Drone gets bad when I pull my 4000 lb trailer in 6th. I had to put in tow/haul mode before I had nervous breakdown....

Finally got to tow with mine. Towed approx 8k travel trailer through Adirondacks and with 3.73's it did fine although I'd probably prefer the 4.10

 

[109rfan]

Didn't know ram could tow inverted!!

 

[hemi1282]

Got my windshield chipped a couple days ago driving behind a 18 wheeler damn rock fell off his trailer man I was pissed so I pulled him over in the middle of highway told him what happened, followed him to his company and told'em about it & they offered to fix it, went to a glass shop to see what they can do, said the hole windshield would have to be replaced cause it hit on top edge I was thinkin aw **** they ain't gonna pay $200-$300 for a windshield, got a quote on it come to find out this damn window is $800 wtf, called the company back they said they'd take care of it 100% I was like damn I ain't never been this lucky, why are these windshields so high I replaced one in my 2010 sport it was $200 somthin

.. i don't even want to know what you have spent so far... but it looks good... that red looks a little light.. but still looks good.

 

[mowin]

Not my style, but looks ok. The only one who needs to smile when behind the wheel is you. Enjoy the ride

 

[SETEX 6.4]

Looks awesome.
I would like to know more about how you like the BDS 4 link lift.

 

[mtnrider33]

I would've been happy with a 4" lift, but was wanting the BDS 4 link so settled with the extra height. BDS only offers the 4 link lifts in 5.5" for our gas trucks. I test drove a few stock 6.4L trucks and I will say that there isn't much difference with the handling on this lifted truck. All the components are great quality and I opted for the add-ons like longer ss braided brake lines, upgraded shocks, dual front stabilizers, etc. The 4 link setup has a clean look and you can tell in the driveability that the front axle geometry was something they considered in their design. It has 5.5" lift in the coils up front and 4.5" lift in the rear coils.
