I said I would post my impressions of

[SteveSierra]

all I can say is....            

No noticeable loss in low end at all.  In fact, my lame ole' SOTP meter says I picked up a few hp.  It does seem a little louder than I thought but I like it.

They were able to put the 2 1/2" pipes out behind each rear tire on a 45 degree angle with 22 inch long 3 " slash cut chrome tips.

It looks sweet and sounds great.  I'll get some pictures up over the next couple days.  Oh yeah, the mufflers are 2 50 series Flowmasters.  

The 6.0 sounds awesome with true duals.  Should be this way from the factory!  Well, maybe not with the Flows cause they definately aren't for everyone, in fact, a lot of people hate em but, true duals anyway.  

If anyone else is contemplating a true dual set up, my opinion is do it.  I don't think you'll regret it.  I don't!

Sounds great Steve.  I'm glad you like it....  I've heard a few 2500 (non-HD) trucks around here with an aftermaket exhaust.  They would have the 6.0L also and they do sound gooood!!!

[SteveSierra]

Now we need to get working on your HD Shane.  What was that I saw you posting?  Something about you wanting to do a 150 wet shot of nitrous??  :0  j/k

Steve, do you have the part #'s for those mufflers? I am wanting to do the same setup as you. Thanks.

IBADHD -

Actually, not with me right now, but they are two 50 series delta flows 3" in and 3" out.  The place I had do this welded a 3 inch to 2 1/2 inch adapter on the exiting side of the mufflers to fit with the 2 1/2 inch pipe that exits on either side of the rear tires(I suggest getting some 22 inch long chrome slash tips as 2 1/2 inch pipes coming out might look a little small after having a 3 1/2 inch pipe on there).

Flowmaster apparently doesn't make a 3" in/ 2 1/2" out 50 series muffler so you have to get sorta creative.  3 inch exit pipes would have taken away alot of bottom end, so I went with what the muffler shop guy and Flowmaster suggested.

If anyone is from my area, I can recommend a great shop for doing this.  I feel they did a top notch job.  

They actually replaced the exhaust system on my very first car(79 Monte Carlo) about 16 years ago.

If I can find the part numbers, I'll either post em here or email em to you.

Steve, what offsets did you use? Offset in and center out, center-center or center in and offset out? Can you see the mufflers from the side of the truck, do they stick out from under the frame real far? Thanks.

[SteveSierra]

1BADHD -

They are offset in and center out.  The incoming pipes are at the bottom so the mufflers are kind of up there.  They are placed in there vertically side by side with about two inches between them.  They definately take up less space than the stock muffler.  That thing is an oil drum!  But then again it had 2 3 inch pipes going in and the 3 1/2's coming out.

I was going to post some pictures this week, but ever since last night it's been raining and is supposed to through Friday.  I might take some pictures in the garage, but the lighting isn't all that great.  Don't know how well they'll turn out.  I'll email them to you later tonight if they turn out okay.  I'll probably upload them to my picturetrail site too.

Thanks. Where are you located anyway. It sounds half way close to me, but..........ya never know.

[SteveSierra]

Northern Delaware.  About 30 mins. south of Philly.  I was Going to ask where you were.  I'd then just say  I'll swing by and you can hear it in person if you were close enough!  

[1BADHD]

Well, were are not exactly close. Unless you consider couple thousand miles close. I live in Southern MO, about and hour south of St. Louis. GO RAMS!!!

[SteveSierra]

Errr, um....not exactly the next county over is it?  :0

I've got some pictures, they're lame because I had to take them in the cramped garage, but you might get the idea I was talking about.  Next sunny day(whenever that'll be) I'll get some better pictures.
