I'm sure this subject might have been beaten to death but I have a bit of a different question than normal...
A friend of mine has a Darj dually w/ the 8.0L V-10. Recently, he added dual exhaust; well, he added a Flowmaster w/ dual-output. He's not real happy with it and says it sorta sounds like a V-6 w/ dual E. I actually thought about doing that to my X until he mentioned the odd sound.
Is it the extra 2 cylinders causing the oddity? Anyone out there have any thought/suggestions?
TIA

most 10 cyl motors sound kinda funny. you are not going to make it sound like a big block Ford or Chevy. i also think there are good single exhaust catbacks out there that will give your truck all the power possible. a quality set of headers and mid-pipe is where you will gain horse power not a catback(catback is the exhaust system behind the catalytic converter, and is usually imune from federal and state emissions laws). if you choose to go the header and midpipe route; check with your local state laws because if you have periodic inspections,you will not be a happy camper.

Kevin,
I know when I put my exhaust on, the guy who does my work recommended against a Flowmaster on a V-10, he said it sounded strange. I personally don't know as I haven't heard one. |

I too am interested in modifying my exhaust. I know there are a ton of options - I never heard that the flowmaster sounds funny on a V-10. I'm sure there are alot of people here runnig those - I've seen many posts on guys installing the flowmaster P40 without complaining about the sound. There are even sound bytes on some posts, but i have not been able to get them to work on my crappy computer. Anyway, I'm looking for feedback on the gibson catback dual exhaust kit I've seen advertised on this site or borla kits. Good luck on the exhaust mod  |

I installed a Magnaflo system ( atback only) on mine. I was also told that I will never get that real throaty V8 girrgle that we all love. V-10's just have more of a muffled grrilge to them....period! Their is a pool guy that works on my nieghbors house and he has the flowmaster. It is kind of strange now that it is mentioned. I asked n=him bescuase I thought is sounded off just abit. It is louder! I deffinetly hear him turning the onto our street.
Since the sound we all love is not achievable go for quieter more high precision tuning sound. I can not complain about the straight Magnaflo the truck revs much  quicker. |

now that we are talking about exhaust only, i think im safe to say that our Duramax monster is very quiet. i dont know which pipes we are using (not my yob man) but i will find out. i will put this muffler on my X. 600 rear wheel horsepower and over 1000ft lb of tq, and its quiet. i have had trucks in my shop that are obnoxious as far as sound. i personaly dont want to hear it in the cab. i do like the diesel sound.

I run Borla headers and catback and am satisfied with the sound. It is VERY TRUE the V10 will not have the sound of a big block V8 no matter what exhaust system is used. I've heard and seen every possible combination.

sorry to dredge this up from the past but I just stopped by one our local 'shops' to inquire about this very thing. They refused to do a dual out setup on my Excursion due to
"limited clearance between the gas tank and rear axle"
does this sound right to you guys? I know others have mentioned that they have two out pipes and also now that I am wondering...whats the benefit to two out pipes anyway.

There is benefit for a gas motor vs. diesel. Any dual exhaust setups you see on an Excursion should only be on a V8 or V10. The benefit is increased flow due to less restriction of having two exhaust headers or manifolds being forced to exhaust through one pipe. Any highly-tuned motor will typically have dual exhaust with some sort of equalizer between the two pipes (via an x-pipe or h-pipe). If the exhaust shop knows what they are doing, they will build a system based on your engine's power output and your driving requirements.
While I haven't looked at the other side of the rear of the Excursion to see if it would clear an exhaust pipe, I find it weird that they refused to do it based on limited clearance between the gas tank and rear axle. The gas tank is behind the rear axle. I have 5" exhaust wrapped up an over my rear axle, I have to imagine 2.25" or 2.5" pipes can fit over the axle and out the rear/sides without much difficulty.
Here are a couple good explanations:

Man I hate to "kick a dead horse" with this subject but I have to ask......(thanks in advance for not beating the new guy for asking exhaust questions!) 
From what I am reading a lot of you guys are against the flowmaster. I am in need of a new exhaust system on my X. Its currently stock. All the reading I have done really doesn't point me in any one direction. Dual, single, Borla, Flowmaster, Gibson, Magnaflow, etc.
For some info the truck will be pulling a trailer (with quads) soon and for the most part is a daily driver through town. It sees a little bit of highway every week. Also, I am running the K&N intake system as well. Would a "dual" be too much for this? Sound really isn't too important to me rather than performance.
Thanks a lot for your help guys!
