huh...power adder 20.....what "power adder" are you talking about??

LT will give you more than a few HP......CrazyAl reported 20 with the combo.....I am not going to doubt anything he says really.

A power adder. Any type of F/I or nitrous.

20, no. Maybe 15 if he dropped the cats. But that is headers/H pipe. Headers themselves dont add much to a N/A car. A power adder will really wake them up

The combo of an O/R pipe and LT's you may see 15 like i said.

There is quite a bit of dispute over how much power they add. The optimists claim 20-25. The pessimists claim under 10. Most would suggest between 10 and 20. Brenspeed (and I would think they would know) told me about 10-15. Modified Mustang magazine added headers with cats, intake, and tune to a car and picked up 40 HP total (of which, at most, 25-30 was from the intake/tune).

The thing that no one disputes is the sound. If you've got the money laying around to put them on, then do it. They make the car sound incredible,completely different. There are so many S197s out there that it helps to set the car apart from the rest, and headers do that. Those people who think their Stinger or Flowmaster axlebacks alone sound good really don't know what they are missing.

No doubt, the sound is amazing. The performance is questionable though

The X-pipes are catted. And the setup costs $2800 with the 89.00 per hour for labor. Took 7 hours!!!

I have basically the same set up except the side exhaust with magnapacks but it does sound bad ***, i basically was looking for more of the sound out of them at this point but i felt some seat to pants difference but that just could be cause of the sound change idk. It feels like its got quite a bit more low end torque as well.

Definitely get that!Just the exhaust without a tune or CAI is mostly useless. Having a high-flow exhaust without a high-flowing intake system won't do anything for you. See my sig below - before I added the cams I was at 306 rwhp with the exahust, intake and a tune.

Magnaflows are my all-time favorites. In my other (prior) Mustangs I've had Borla's, Bassani, and Flow Masters. All of them performed great, and sounded great, but the Magnaflows are the only one's I've had thus far that sound great, perform great, AND don't have that horendous drone at cruising speeds. I can actually hold a normal conversation in my car when cruising. I could never do that with those other brands.

This is what it sounds like: http://video.google.com/videoplay?do...62242206882486
