well with the help of Darren WS6 finding some parts for me. i found dynomax bullets 2 1/2" in and 2 1/2" out 39.95 each. a splitter pipe thats single in dual out made by magnaflow stainless steel 26.00 each. and finaly edelbrock tips 2.5" in 3.5" 49.95 each. this is gonna cost me 327 bucks total... the tips cost more then my whole exhuast - the headers lol.
my truck is wanting a new exhuast too. i turned a coner to day and herd CLINK looked in my mirror my 3" to 3" adapter cut-out and muffler are sitting in the road i turn around and grab it my 3" to 3" adapter is messed up i ran it over but the cut-out is fine... new adapter and im good to go. that passenger side hasnt had good luck i had the muffler on that side fall off before too. oh well
Here are the links in order Bullets, Spilters and tips

well you knew my old exhuast set up was 3" true duals so going to 2 1/2" and a real muffler improved my low end and the truck seems to move without alot of throttle now. yeah i know 2 1/4 is the best for true duals but 2.5" works and its deff working alot better than 3'

To put it short -
The only way more flow = loss, is thru the tune.
I think Shifty's tuned ? If not, he has a Dyno sheet that I'm sure he'll post to show what that 3" set up did to the powerband running the stock tune.

how does a tune make up for the law of physics?as in the static pressure , velocity pressure, and total, pressure of going from a 2.5 siso exhaust to a true dual 2.5" exhaust on a na 4.6?it doesn't my tune didn't get touched once i added my true dual 2.25" set up on my na 5.4-i'm all ears on your explanation j brew....

that's like having a cam witha profile for all top end and porting that compliments it- then saying- oh tuning will give me all my bottom end i gave up with this cam profile and porting-i think not...

Your thinking 3" = Exhaust gases weighted down, no velocity, scavenging problem right ? I know. I'll see if I can find that sheet.

Jbrew my dyno run is when i had shortys rember? Shorts Vs longtubes. i had shortys no cats into dynomax superturbos. made 190 HP and 234 FTlbs at 4,200 RPM. yes i am tuned now Jbrew Sniper custom tuning me and my buddy went half and half. i now have the 3" necked down to 2 1/2" true dual into Dynomax ultra flows.
once i get the bronco tank in and my dual lightning style tips ill go back to the dyno. Longtubes made a diff. going to 2 1/2 made a huge diff and running real mufflers. but the sniper brought it all togther. now my computer knows what to do with all the bolt ons.
My dynorun was to prove power shortys over longtubes.
Thanks for all the support guys. Jbrew thanks alot for the help and defending me here. You still in michigan???

Yea, I'm in Michigan for 20 more months - school 
Hey, how much pipe were you running when you hopped on the Dyno? Those are pretty good numbers for RWHP. Did you have those Super Turbo's dumped under the cab or something ?
I remember JMC and I guessing what your Dyno run would be before you went (way back when), you surprised us both, but I guess I forgot your total set up. ?

Yes it went from the shorty to the down pipes into super turbos no pipe after the super turbos just ended right there. Ya rember we all took bets on my numbers i said 200 and 240 Ftlbs you all said i was crazy. and you guys guessed way low like 150 and 180 ftlbs.
we should get togther and go cause some trouble some were Jbrew.
hey for 150 bucks i could tune your truck with the sniper if you want.

Yea, I guess that's still confusing, - well, I don't know exactly how to figure that out with no pipe lol. Your torque # percentages were good as far as FWHP - RWHP IMO. Peak only moved up 200 rpms from stock.
I know my 5four sucked w/no cats and factory tune, but hell, I was running all my pipe - tail-pipe as well lol. So yea, I was trapping gas.
