There is lots of exaust talk, but i couldnt seem to find much information in just a muffler replacment. I am looking at the two exhausts, magnaflow or aeroturbine. What are the sound difference, there are a few sizes in the magnaflow. i am looking for a deep diesel sound, that will tell people that yes it is a cummins but something that will tell the cops no i dont want a ticket or the attention. i was thinking something like the 24 or 30" magnaflow vs the 4040 aer turbine. anybody with these have any comments? also how much was it to get installed or did you do it yourself? thinking about keeping the cat on at first and if i need more sounds remove it afterwards.

I have the 20" Magnaflow. Before going with this muffler, I had it straight piped for about 3 weeks. It sounds much better than the straight pipe IMO. It's not too loud, but you definitely hear it.
I had a shop do mine, but I can't remember the price. I think it was less than $200. We already have 4" from the turbo back, so I didn't see much of a reason to spend the extra $$ on a full exhaust, so I went with just a muffler replacement and kept the CAT (for now).

I run a Banks muffler, it sounds great but for me it too quite. I only use the muffler for the colder conditions, don't wanna piss off the neighboors to much when that high idel kicks in during warm up at 530 AM, haha. Banks and Magnaflow pretty much have identical mufflers.

I hear alot of people hearing talking about the MBRP muffler though. Its something you should deffinatly look into. Everyone seems to love them.

Ditch the entire exhaust and do a Magnaflow #15989 from turbo-back.

I replaced just the muffler as you are talking about. I got the Aero Turbing 4040L, the L means I got the additional resonator on it. It cost 50 more, but I didn't want the extra noise and drone while towing my 5'er. I paid 300 or 350 installed, it was one or the other, I can't remember right now. I found the same muffler online for 300, so I figure I did OK with no shipping charges and just paying the tax and install was about 50 that way. It welded onto the stock exhaust no problem, they just used one small piece of pipe to fill the gap since it is shorter than the stock and the angle is not enough to even tell the tailpipe is moved up at all. I left the cat and it is not closer to the body as you might think, it still has plenty of air space to keep it from burning the cab floor. I really like the sound, it is a steady rumble and does not draw attention. Going between buildings and under bridges really echoes though. Towing it is only a little louder, but the 100-200* cooler EGT's when hammering WOT with the trailer is nice. I can still get it to about 1400* if I hold it WOT in 5th uphill to about 70 MPH, but it did help alot with the take off EGT's and decreased the cool down times a little bit.

maybe i missed it but are you still running a cat?

I straight piped my truck for about three weeks but it seemed to hurt the low end torque, and made me feel bad driving through town in the middle of the night. So I installed an MBRP resonator. Not too loud and not too quiet. The body is only 12" long and gives the truck a great deep tone, without being annoying. Best sounding muffler I have ever heard. I think it was only like $85. No in cab drone, but everyone still knows I am coming

I put the non-resonated aero tubine 4040 on mine and love it. It seemed a bit loud the first few times that I drove it and especially loud the first time I towed my 5er. After I got used to it it didn't seem so loud and definitely nowhere near as loud as a straight pipe. In fact, I think it just sounds plain mean.

As a bonus, I picked up between .5 and 1 mpg! I don't know that I picked up any power/ torque but the truck seems to be more responsive and it seems smoother and definitely feels like the turbo is spooling more quickly.

As a side note... I have a magnaflow system on my LS1 camaro. I really love the sound of that LS1 winding up through 6000 rpm through the magnaflow! Magnaflow is a high quality piece in my opinion also.

I don't think you could go wrong with either one although I have no experience with the Magnaflow for the Cummins. Good luck with whatever you decide!

I am still running the cat, I assume that is why I have not seen incredibly lower EGT's through all ranges. Also the reason I am not seeing any mileage increase. It does cool off faster and the max temp is about 50* less than before and on a hotter day (doesn't make much difference once you hold it WOT for a few miles, the ambient temp is useless to cool that much heat inside the engine).

 

[NickBeek]

dieselracer, where did you get the MBRP from?

 

[ROMAD]

I have the Aero 4040 on mine. I paid $301 installed with a 5" tip. I love the sound mine puts off. Not too loud until you really get on it. I also left my CAT on.

 

[pooperscooper]

has anybody installed this themselves. i went to every shop in my town and they all told me 215 for just installation. personally i am cheap arse when it comes to paying for labor. i would much rather pay 215 dollars for tools and my own time to do it than pay somebody to it. looks like a pain to do because of the drop out of the muffler. looks like you would have to bend an s piece or just run the muff at an angle (bit getto for this application).

 

[ROMAD]

You should be able to go to a local muffler shop and get the extra pipe you need. I dont think it would be that hard if you have some basic welding skills and a Mig Welder. Looking back at it now and watching the guy do it, I could have done it myself in about 2 hours.

 

[MSHarnett]

Get some flex pipe, it makes it much easier to connect pipes that don't line up right. I perfer to use band clamps rather then welding though. A weld is great and all, but its nice to be able to change when ever you want. I use a muffler in the winter, straight in the summer, changes out nice and easy.

 

[me1magoo]

Mine is at a slight angle, and it raised the tip a little bit. You can't tell unless I pointed it out. The muffler is visible through the wheel well, but no one knows its off unless I tell them it is not supposed to be angled up. NOT a big deal for me, and flex pipe has a habit of rusting through and leaking.

 

[pooperscooper]

did you have to add a length of pipe to get it to fit? I really like the aero turbine but not sure i want to spend that much on a muffler. I cant seem to find just the mbrp muffler by itself.

 

[pooperscooper]

I just did a search on mbrp website and they make a muffler with the bend already in it. it is a direct replacment for factory. mk96116 is the model number. problem is i cant find anyone that carries it online, anybody know where to get it?

 

[me1magoo]

I got mine at a local diesel performance and exhaust shop. They did add a piece of pipe and I didn't have a problem with them welding it all in cuz when that is worn out and rusted up I will just HAVE to put on the stacks. To hell with the soot on the trailer, maybe I will paint flames on the trailer and have the soot blow on them!!! Yeah, the AT is nice, I don't have any others to compare to though.

Mbpr Mk96116

If you will GOOGLE MBPR MK96116 you will see several on line places to buy this muffler I have seen $150 to $180

thanks, i ordered my stainless mbrp lastnight, think i paid 172 shipped. Funny the title reads magnaflow or aero and i went with another, thanks for the help guys. I will be sure to post back how installation goes.
