Ok here's what's going on. About a week ago I was over a friends house helping her move. Found this h pipe in her garage and she says it was to her ex's mustang. said it was the same body style as mine a s197 gt. She let me keep it as she didn't need it. Now the dilemma is I've been searching online for about a week now trying to figure out what brand this is exactly and if it's even an h-pipe for our mustangs. She swears up and down that it is but I'm not turning up anything that look exactly like it. I'm handing it over to you guys now to see if you could do better than me and identify this piece!

It looks like its for a 3v but it's a little hard to tell, measure the pipe diameter on both inlet and outlet sides. I think it should be 2.5"

I have the exact same pair. It is in fact an H pipe; to be exact, its an offroad h pipe. This simply means that it removes the catalytic converters to increase flow and sound. You should see gains in horsepower of 10-15 horsepower and it will be EXTREMELY loud and will cause a MASSIVE grin to swipe across your face. Power gains are not noticeable until top end. The only problem is that he has welded the "h" section, securing the width of the pipe. This is good to enaure no leaks, however, if your headers are any wider or narrower than that he has welded them it, it may not bolt up perfectly. Chances are though, that it will fit without a problem. All you need is to do to install is undo your (2) o2 sensors in your factory catted h pipes and undo the two bolts at each side of the headers and the bolt holding the h pipe to your axle backs, slide the old h pipe out, slide the new one in and reverse the process. Easy 10 minute install for so much fun and easy, free power! Hope this helped! Enjoy!

Looks like a custom made one, or at least the crappyest one possible for purchase

And it's also looks like it's for a setup with long tubes or at least 3/4 lengths

Measured it out and your right 2.5 for both outlet and inlet.

Ok, that would explain why I can't find any brand that looks exactly like it There's numbers that looked like where etched into it but when I tried google search nothing came up from those either.

I wouldn't say it's that crappy, but it definitely looks like a shorty midpipe for long tubes. The section of the midpipe before the H is way too long and straight to still have enough room for a flow tube to go up to the manifolds/headers, so I'd say they are for longtubes.

Sounds like the perfect excuse to get long tubes!

Your dating his ex and stealing parts out of the garage. Watch out for your car, he probably doesn't give a damn about the ex, but parts for his mustang...

Who said anything about dating? That's my girls friend haha. And from what I understand they broke up a few years ago and she was paying for the car....so he can't be too mad!

The power is through out the powerband. Most dyno will show that. It also doesn't get EXTREMELY loud until after LTs and straight mufflers.

That's a bunch of bull. My car is 100 times louder than without them. That's what they are mostly intended for. And I know first hand where the power gains are.

It is not a bunch of "bull". I have all said parts on my car. What you consider loud, may not be to others. The h and x pipes add sound but they do not get extremely loud until headers or straight mufflers are added. Even then, unless under WOT, they are more than tolerable.

As for gains, your estimates are GENEROUS especially when many of the best h and x pipes showing gains under 10whp/tq. They're great for the price but your comments are over extended a bit. Don't get so defensive.

It should also have two holes for O2 sensors on the driver side At least that's how it is on my 2005 GT
