Muffler? Which One?

[JTCrow]

I recently purchased a Magnaflow muffler for my 2003 CTD on ebay. After I received it, I went down to my local auto shop to have it installed. The shop told me that it would not work on my truck because it was designed for earlier model Diesel trucks with a "straight through" design and would require additional work to have it installed.



I sold the Magnaflow to a friend, and took a small loss, but I need help as to which type of muffler will work on my 2003. I do not want to replace the whole system just the muffler. What I would like to have is a deep rich tone that is not offensive but has a good rumble to it.



Any suggestions from the group would be great. Thanks!

I ran mine straight piped for about a year, and added a Monster Muffler about a month ago ... ... ... ..... it's tooooo quiet!

 

[JHardwick]

you need a new shop too, unless it was actually the dia. that was incorrect

Sounded like bs to me... ... ... .

Boy was that shop full of crap!!If you would like a nice rumble when you get on it but sound stock with no resonation at speed I woould suggest a MBRP muffler. Have been very happy with mine for 35,000 miles now.

The best muffler is NONE... .

I have an MBRP as well, very very nice. Ebay dude, got a cat back for 200 bucks.

They may have meant they needed an offset pipe.



I would try it with out a muffler and see if you like it. If you do then get an ME kit. Those little shorties like the little MBRP don't do a whole lot. It is about 18 inches long, 4 in straight through, and is only 6 in in dia. How much baffling can it do. If you get a straight little muffler all the exhaust companies sell the offset pipe that goes in front of the muffler. Lots of times when you go to a muffler shop they might not be able to help as much as you think because they are not setup to do 4 inch. But if you take them all the parts they need you should be just fine. I would make sure to get some band clamps instead of using the u-bolts in case you want to make changes later. The u-bolts crush the pipe too much to get it back apart easy.

The best muffler I've heard is the Bassani.

if you straight pipe it do you still keep the resonator?

 

[16919]

NO... ... ... ... ... ... ... ... ... ... ... . are you referring to the cat... ... ... . you newbie truck owners have em but I don't. :-laf

 

[Megadesertdiesel]

i was not refering to the cat. i have an 06, and my resonator (6" round and 14" long) is above and slightly in front of the rear axle between the muffler and exhaust tip.

Actually, those little shorties do a lot more than you think. When I stacked my truck, it was unbearable inside the cab. It's a reg cab, and I couldn't fit much of a muffler underneath, so I got a magnaflow that's about 17 inches long. Made a huge difference.

Another vote for the STRAIGHT PIPE! I love the way mine sounds. Nice deep rumble, no extra noise in the cab when cruising, and gets a little attention of you get on it... . perfect.

The exhaust on my 03 has rusted off twice in front of the muffler and once behind. I brazed it back together in front, but now the tail pipe is off and shot. Funny how they make these pipes out of some kind of galvanized steel and then mig weld the seem with carbon steel wire - thus the pipe rusts along the seem through the whole length. Ridiculous!



Anyway, I bought a 4" straight-through Mack muffler that is about 12" long, some 4" straight pipe, and a 4" to 3. 5" reducer to go to the pipe in front of the existing muffler. As per the offset, there is a slight offset in the pipe in front of the muffler, but if you cut that pipe off in front of the offset, you should have no problem with the straight-through muffler.



Question... where is the best place to buy a new tailpipe, preferably stainless?



Thanks,
