well finally got around to peeling the muffler and whatever the other thing is under there off, poped in a piece of 3" and clamped it in. you can definately notice the difference, but its fine going down the highway. have to see how the locals deal with it, i'm all

 

Youll eventually notice the drone that comes with it

Past 2K RPMS mine gives off that drone, i just back off it a lil bit and it aint so bad to deal with.. Sounds sweet eh? he he he he.. Local and neighbors will now know that you are coming, besides, your 24V idles more clackety and loud than my 12V does, and for that im jealous he he he he he.. Enjoy your new "free flowing" exhaust..

A straight piped cummins is a wonderful thing.

 

Straight pipes save lives!!!!!!!

 

Straight piped mine as well(4" turbo back) and it sounds great. Very happy with the sound.

 

With a 5in. straight exhaust the drone is pretty loud at about 2100 rpm's but I think it sounds sweet.And towing a trailer it sounds just plain bad!No CTD should have a muffler.

 

I part of the straight pipe club as well!!!

No drone at all... Matter fact most people that ride in the truck don't notice the straight pipe until there roll down the windows.

Local cops don't even mess with me. They just wave and get jealous... He's got a Duramax and GM won't let him pull the muffler off... It will void the warranty!

I've been told I can be heard up to 2 miles away... That's while I bury the skinny pedal in the carpet!

Any one need a stock muffler setup???

 

i went up and down the highway today, no drone for me.

 

I have mine straight piped with 3 inch duals. Now that produces a cool sound & twin black cloud tornadoes in 5X5 on the Comp.

 

upersleder, where's a good place to find the 3" pipe to delete the cat and muffler?

 

You'll love it!! I wouldnt go back to a muffler for anything!

 

i got my 3" from a repair shop and had them expand both ends. i would think any muffler shop or reapir shop that does 3" would be able to help you. then just get two clamps, take your muffler and stuff off and slide the pipe in. took me about 1/2 hour

 

my 12 valve at higher rpms sounds like a semi but the 24 valve sounds like a jet o well sounds awsome any way so i gess i have the best of both worlds untill i sell the first gen

 

u oughtta get stacks! if you like the straights out the back, and if you think that you want them a little louder, its the only way to go. i drive with the windows down all the time jsut to hear it. ive got a 4'' downpipe and 4'' all the way to my 5'' stacks. see gallery for pics. i love em

 

Yeah, gotta love the sound eh? I have never had any problem with the drone either. Not even while towing.
