Mine was straight piped for a while. I loved it, you could hear that beast from atleast a mile away if I rally got on it. I have the MBRP cool duals now, They arnt as loud but look alot better than the stock pipe. Next is a 5" exhaust w/stacks.

the new trucks sound sweet straight piped IMHO...

but I think they sound kinda crappy w/ an aftermarket muffler... they sound like a rice burner V6 or something

straight pipe it!

My truck kind of has that ricer sound to it, but my MBRP muffler is basically a straight pipe so I assumed that replacing it with a true straight pipe would do nothing but amplify the ricer sound. Am I wrong?

find a local truck stop/shop and they should have it. you need 2x 4" lap joint band clamps, and enough flex pipe to make it. clamps are ±$10 cdn and 4" flex is ±$5cdn per foot last time i purchased them..

Here is the list I PMed to powerstrokin03;

Here is exactly what you will need to order to do this your self;

Code: M085171 (Donaldson muffler $73.64 X1)
Code: GALV4 (Flex tubing, 2ft $10.06)
Code: 4310-436 (Aluminized Steel Tubing 4" X 36" $23.22 X1)
Code: J009606 (Aluminized SealClamp 4" Pre-Formed $8.22 X2)
Code: 426-240 (U-Bolt Exhaust Clamp 4" $4.29 X2)

Total: $123.36 plus S&H

All purchased from AirFlo.com

I also used some pieces of scrap 1'' angle iron to hang the new muffler.

You will need a MIG welder, sawzall, and a few other basic tools to complete this install.

yup... you'd be surprised what even the smallest muffler/resonator will do to the sound...

I'm assuming your muffler is 7-10" in diameter and 25-30" long... even though you can see straight through it, it's doing a LOT to muffle the sound. don't get me wrong, it's not hurting performance, and if you need a quiet exhaust note, that's fine and dandy, but those 3rd gens just don't sound right w/ a muffler... I'm not a huge fan of earlier CTD's w/ "louder" mufflers either, but they still sound like a straight 6 diesel... the 3rd gens sound like V6 Acura or something

BUT, I've heard a few straight piped 3rd gens, and although they don't sound the same as the earlier trucks, they still sound **** good IMHO!!

the mufflers take all the harshness off the exhaust note and leave all the wierd soft flutter... straight pipe leaves all the rough edges on the exhaust note, and they cover up the 3rd gen flutter no ricer on earth can come close to the sound of an uncorked 5.9L I6 turbo diesel!

If I may borrow a picture from DPPI's website, my muffler looks like this if you look through it:





It's a 4" pipe with the little perforations inside of a 6" pipe approximately 30" long.

I'd go straight pipe if I could hear someone else that had one first. I don't want to go to the expense of straight piping it only to have the same ricer sound...only louder.

that's what my muffler looked like inside... are your louvers facing forward or backward?

I've heard a few straight piped 3rd gens, and they sound good IMHO... my buddy's 600 w/ the louvers facing backward sounded pretty dang good actually, but with a quieter "performance" muffler, they just don't sound right to me...

but straight piped, they sound good!
