126whp/130wtq.

I was hoping for 130/135, but whatever. I need a REAL exhaust and a tune and I think 140 isn't out of the question.

Not bad, what mods so far?

Listed in the videos.
Steeda SRi and an F2 4-1.

I figured you where shooting pretty high, didn't want to break your heart though.

Talk to Roger about new exhaust yet?
I agree that your current exhaust is a big part of the lower than expected numbers. Smoother pipe, less restrictive resonators (see below) and larger diameter and you should gain the 5 at least. Honestly I'd wait on the tune. Do the exhaust first, get some adj. cam gears then go after the tune. D-tec is like the zetec right? Can sometimes pick up a few HP from cam timing.

There is one more I'm looking for but can't find, it's cut-aways of various muffler designs.

Basically the muffler I gave you works, but can be restrictive, the resonator you have is the same baffle design and can be restrictive. I doubt you ever have but if you look in the can I have on the back it's a straight through design that is done the right way, none of the louvers protrude into the exhaust flow, it's more of a steel mesh looking deal.
Dynomax mufflers are a similar design, but they don't use SS internal components.
Flowmaster uses baffles and no packing, alright but can sound tinny W/O a resonator.
Magnaflow is flat out junk. Thin cases, shitty welds ... but they polish them to look real nice, yay.
Hooker, my favorite. Simpler has an aerochamber on the GTA, I had one on the Conquest. Awesome muffler and crazy how much it can actually quite a car, I mean you can see straight through the damn thing.
Stay away from anything that says 'turbo muffler', all junk.

Realize you know most of this already, but ...

Well as of now I'm going to leave the exhaust. I have to fix a rattle problem that has turned up and I FINALLY got around to installing my rear sway bar. I tell you what, that is the single best thing I have put on yet. I noticed a LARGE gain in control at speed around corners. It's pretty crazy how much just the stock SES sway bar added. I just have to get the small leak fixed, the weird noise with the exhaust figured out, and I should be set for PG. Anyone else going to bu there?

Also, tell me what you guys think about the way my exhaust sounds.

Exhaust sounds good, maybe a more open muffler design would give it a bit more depth of sound though.

I don't actually have a muffle right now. 3 resonators.

What brand of dyno out of curiosity?

DynoJet. MAP's dyno has been know to be giving to AWD cars, and be pretty accurate to 2wd's, from what I have heard.

Nice.

I forget, was yours an auto or manual?

My 07 w/ auto and steeda sri did 114.5 at the wheels on a dynojet awd dyno

His is a manual

How much did that cost? Did they do any tuning?

I wouldn't have MAP touch my car for tuning. I doubt they know much about Ford motors. $75 for 3 pulls with a quick cool down.
