straight pipes

GambI80, when u put the 7's on... It didn't have that extra deep hmmmm to it? I heard a guy come off the hwy jakin it up n it was so loud it was kind of poppin. Not in a bad way cause em 8" stacks sounded good. I dont drive anymore but when I hop in my truck it's like my medicine.

 

I work for the railroad, so I get to run a short load 2-3 times a month tho. Even tho I ride trains everyday, I just can't get trucking out my system after 7.5 yrs otr. My driver been hounding me bout some straights, so that's why I need all this good feedback I been getting. Once again, thanks a lot n may god continue to bless u all

 

I just threw a set of 6 inch straights on my 05 twin turbo Acert and it's not loud at all. Running 2 turbos keeps the noise in check. Sounds perfect to me and made an incredible difference in how that truck runs.

 

So is that a good thing to you or not w the sound of the 6" pipes?

 

Personally, I couldn't be happier with the 6 inch pipes. I'm not a professional driver, I farm. My truck sees about 15k per year hauling 100 to 110 k. The sound through the 6's and twin turbos has a nice growl under acceleration but is not annoying at idle or cruising speed. I like the performance increase, and being able to pull up to an elevator or ethanol plant and not have to shut down my engine to communicate over the intercom is a definite plus. It sounds similar to my brothers b model cat in a 379. He is running donaldson mufflers with 6 inch stacks. You definitely know it is there, but it is not obnoxious. Also, my turbos spool much faster and sound wicked as they hit 50 lbs of boost.

 

I wish you would quit your going to talk me right into it.

 

Oh just buy the pipes lol

 

Does an 07.have a DPF?

 

No its just a reg cat w minor changes from the 04-06's I believe. I think 03 or 04 is when they went to twin turbo

 

My buddy works in a shop and they have a TT 550 KW and instead of replacing the factory muffler they just got rid of it. No mufflers at all and it sounds just like my dads 6nz with 7's and a PP muffler underneath
