This is not a chip question, but I was not sure how often you checked the exhaust forums.
Anyway, you said with all the testing you have seen. That Magnaflow was the only cat back that made gains.
Magnaflow does not make a cat back for my 99 F-150 5.4L Reg cab, short bed(flare side).
The only manufacture that does is and Jardine.
What is your opinion of Jardine, will I loose low end? Or what should I expect.
They do not use oversized tubeing 2.5 inch is all, so I figured I would not loose back pressure.
What do you think?
Your expertise would be helpfull.
Thanks,
p.s. I have not recived the cat back it yet
I also dont want a Gibson.

Hi **** 4,
Good idea, as I haven't had time to get to the Exhaust section lately.
Hmm, I think we might have a bit of a misunderstanding there..........
What we said specifically as that the Magnaflow was the only system that we found to increase *torque* across the board, at all rpms & throttle positions. Magnaflow is *not* the only system to show "gains," every cat-back system we reviewed showed solid horsepower gains!
Almost anything you do to open up flow on the exhaust side will get a horsepwoer gain at higher rpms & heavy throttle positions, but it's what happens the *rest* of the time that matters far more in these heavy vehicles.
Most systems showed clear decreases in torque, some as much as 25-30 lbs./ft. from idle thru 2800+ rpm.
You know, it's funny, we've just by luck I suppose never run across a short-cab short-bed F-150 situation with the Magnaflow, but I just looked, and you're right, they are for the SuperCab's & Super Crews. That may be just a length issue, but I don't remember well enough to say for sure, I'd have to get up under a short-cab and a SuperCab and take a close look.
Jardine is a company I used to talk about a *lot* a few years ago here, as they used to be one of the better flow-engineered systems. They invented the "Tri-Y" header concept years ago to increase low to midrange torque. They have changed quite a bit in the last couple of years, to the point where I really couldn't say if you're going to be happy with it or not from a torque standpoint. They are now louder, we have had a couple of people complain that they "droned" inside the cabin at cruising speeds. They always sounded very nice, muscular, and I'm sure you'll get a solid horsepower gain, but we just don't know how the torque is affected. Someone I talked to a few months ago claimed that Jardine had changed over to using Magnaflow mufflers, something I can't confirm and have never checked out. I'm sorry I can't give you a more informed answer on Jardine currently, we used to recommend them quite a bit a few years ago, I just can't say how they are now, it might be fine for you.
Since Magnaflow apparently doesn't cover your truck with a complete cat-back system, you might want to just use the Magnaflow muffler(s) to get that much of their flow engineering, and then have a muffler shop do the rest for you. That's just one thought...................
Give us a call if you'd like to go over this in more detail to explore some other options, etc.

Thanks a mill Mike
I want my truk to sound mean but without my head resonating off.
The Jardine has been on order so the best I can do is wait.
If you or anyone out there has any more info., please let me know.

Hi **** 4,
Ahh, I see, I didn't realize that you had already ordered the Jardine, that just didn't sink in for some reason.
Great! You can tell us about your impressions once it's installed and you've driven it for awhile.
One of the things to look for, the single most important thing (to us, I should say) in these heavy vehicles, is how the vehicle responds on part-throttle, when driven normally. In other words, the affect on part-throttle *torque*. That's the single most important thing we look at, aside from a system being too loud and droning or resonating inside the cabin, etc. Many times people don't pay attention to that for some time, they're paying attention to the sound, and the performance when they nail it, etc. Usually a loss in torque shows up with some decrease in mpg, because more throttle opening has to be used to get the vehicle moving.
Good luck with your new exhaust & let us know what you think of it once you've had it for awhile!
