JLT+Tune = 20-30 hp depending on who you talk to. On an otherwise stock vehicle, I'd expect more along the lines of 20 hp.
Corsa mufflers alone = next to nothing. X-pipe should net you a few hp. ~5?
Ram air is the most difficult. On a dyno, you probably won't see nearly anything. Ram air works best when the car is being driven, and the faster you are going, the more horsies it will produce since the air is literally being 'rammed' into the engine faster.
One question, why not go with the prochamber? They produce pretty decent gains on the S197's. Some have claimed up to 15-20hp. The only thing that's not attractive about the prochamber is the price for your model $400 and something
For the x pipe and mufflers? Well for one I'm a little skeptic about the HP gain claims, and two I think MAC sounds like ####.
I just looked them up. Seems like an interesting idea. I pretty much picked the Corsa exhaust b/c I liked the way they sounded the best.
Did you listen to the black mustang on the site? That mustang also has other exhaust mods to make it sound the way it does. Yours might not sound as aggressive as that one with just the Corsa mufflers.
Well I'm putting the x-pipe on too but ya I saw the black stang had long tube headers and what not. My buddy has corsa mufflers on his 05 GT and it sounds great. I think with an x-pipe and mufflers it should sound real good.

no E-check where i live.
Cool. Any brand in particular?
btw, is the Corsa muffler chambered or straight through?
Straight through
Would it be feasible to beat a co-worker of mine after the mods are installed in an 1/8 mile drag.
he has a 98 c5 vette with only corsa mufflers.
Pypes is likely the best deal on a OR H-Pipe. $174 Shipped from Brenspeed last I checked. Maybe 8 rwhp. An X will net you maybe 2 more rwhp but the make a Mustang sound like a Foreign Car to my ear.
I would try just the ORH with the stock Mufflers first. They are pretty free flowing and actually pretty aggressive without the Cats. To me the ORH + Stock Mufflers also has the best tone of any system I have heard. If you have an M5 the stock Mufflers are actually better than the ones on the GT500. if you have an A5 you have the same mufflers as a GT500.
The CAI/Tune also makes the car a little louder at higher throttle openings.
