I am looking at putting on a new exhaust system on my truck. What would be the best with a real throaty sound?

 

You could go the inexpensive route and do the muffler delete and/or cat delete pipe. Or, I've heard the MBRP muffler is pretty good. The 06's came with a factory 4 inch mandrel bent system so it won't cost much unless you want to spend the $$$. I personally would like to go with the Grand Rock 7 inch stacks with a cat delete. That would have some serious throatiness to it.

 

best muffler is your turbo... just leave it straight pipe after that

 

I just straight piped my truck today and it was amazing, the sound is great, not too loud and no drone at highway speeds. Just make sure you get your exhaust tip out from under the bed or you will pick up the drone. If you look around you can find a muffler delete kit for less than $50. If you pm me Ill tell you where I bought mine.

 

Are you guys leaving the cat on?

 

ofcourse! it looks like its there anyway

totally straight is too loud IMO.

leave the cat for a good sound.

 

I disagree... I'd rather have no cat and a muffler than no muffler and a cat... just a cat kills all the turbo sound and sounds like a riced out V6

 

FWIW. I deleted the Cat and 55 gallon drum of a muffler...I did put one Dynomax race bullet muffler on it and I think it sounds good.. definitely a nice deep throaty tone..

 

Go total straight pipe and if it is to loud get a high flow muffler. A local muffler shop can do it for you and it shouldn't cost very much. When I pull a big load the drone of the straight pipe is to much, but since you have that lift I don't think you are pulling anything.

 

Have you heard a 600 Common-Rail without the Cat and Muffler?? It sounds like a ricer once it gets into the RPMS. With just the cat on and a nice 18" long 6" tip sounds really good.

 

gotta disagree... no cat = sharp exhaust tone with lots of turbo... cat = softer exhaust tone, no turbo, and a nice Acura feel to it...

dynomax bullet also eats up a lot of turbo...

on a 3rd gen it's either gotta be really quiet or totally straight pipe to sound good IMO

 

I have the muffler delete and its not as throaty as my 02 was, not exactly ricer sounding but close to it. Will a 5" tip change this and where do I get one? Not a little short one either about 18" or so. Pics of tips?

 

Look in the DTR Store or contact Lary and can probably find one for you.

 

ditch the cat and put a 5 or 6" tip on it, it'll start singing a better tune

 

Lots of different opinions on this thread so I guess I'll throw mine in too. I'm running MBRP 4" duals w/Cat. Sounds really good and throaty but not too much to handle when I'm on the highway or towing. The sound can change by the tip you use and how you adjust it. But I'd leave the cat in
