I give up....please help
The chart I posted isn't an absolute end all thing. I don't know how much it would hurt you to go with 2.5" pipe. It was just a useful chart that I've found in my time here. Hopefully one of the more knowledgeable members can confirm or deny if you'll be hurt by the 2.5". good luck

You sir, are a mind-reader, for reasons that will become clear, presently.

Haha yea you are ahead of us openclasspro. I'm about 90% convinced I'm gonna Roush it next year anyway (especially if the tax man is in the giving mood). I talked with Neil (I figured Mike has better things to do and didn't push for him) and he said basically what ya'll said (go figure). He didn't seam too concerned about the 2 1/2 beyond that. The X I figure could always be changed by a decent shop if need be. I'm most concerned with the bends before and after the X which he can do well. I have not found a lot of good custom shops that mandrel around here and I don't like shops that hide your truck when working on it. What the heck I've changed it 4 times already so if I have to get an X changed out later it won't shock me and I tend to like a mean SOB that does good work........ fella's.
fella's.

I know he just wants to use 2 1/2-inch and build his X because it's his daily routine and I understand if he has to charge me to get the stock but I know he's going to REALLY jack the price. He does nice work and it looks fabulous but I don't know the power results of his X. Based on what you guys are telling me and the chart, I don't have enough power to warrant the 2 1/2-inch so maybe I'll just wait because I don't want to lose low end. It's just hard to find good shops, especially that do mandrel bends.
I agree with everyone else on sticking with 2 1/4 unless you do enough mods to warrant 2 1/2. I would buy the magnaflow X-Pipe myself. I think i paid like $80 from Troyer for mine.
I really don't see any way he could get his X as smooth as the Magnaflow even if he does it every day. Also by the time he ****s around making it you could have bought the Magnaflow X i bet. How much power will you lose with 2 1/2 and his X-Pipe i dunno but you might as well do it right the first time.
Last is if you let him do the X himself and you are unhappy with it could be more work than ya think. If his spacing is not the same as the magnaflows inlets/outlets you will have to add more bends to make it fit. Possibly even cut it all off an do most of it over.
Do it right the first time IMO and you will not be dissapointed
This is my magnaflow X-Pipe. I see no way he can make it this smooth inside. I have a pretty good idea how he would make his and it sure as hell would not look like this IMO!!!
Oh and how much does he want to do the exhaust with mufflers or without??

Ahhhh! You know what, I think I should put this off until after visiting TP so I don't rush something I'll be tweaking yet again. The old cantankerous bastard will just have to deal with it. We didn't even talk real numbers between the difference but he said "a lot more" when I told him I wanted 2 1/4 and the Magna X over his stuff. Oh well I'll find another shop that does mandrels AND listens to the customer better. Maybe pick up the goodies while at TP.

to start with, a 1/4" diameter difference will make no difference with loosing low end!!!!! Even if you ran straight pipes with no mufflers, the Cats are the biggest restriction you have and anything installed after that will really have a very minimal effect- in your specific case, 2.5" is fine.
Secondly, While an x-pipe is a good idea, unless you're constantly operating at 2500 + rpm the benefit is at best minimal!! To just install an x-pipe on a system (without dyno or field testing first) is almost a waste of $. to field test, install the system complete without the x-pipe. Run a thin line of paint down the exhaust pipe in the area where you think the x-pipe should go- make it nice and long, several feet. Take a quick trip on the freeway, pull the truck back on the ramp and look for where the paint has bubbled- thats where the x-pipe should be located. While professional racers use a more technical method, this works well for street vehicles and used all the way back to the 50's.
