PerformancePac, 2003-04 Mustang Cobra w/Loud Mouth Exhaust w/ High-Flow Cats 575HP

PerformancePac™, 2003-04 Mustang Cobra w/Loud Mouth Exhaust w/ High-Flow Cats 575HP

Get 575 horsepower…with bolt-on parts!

Looking for an easy, cost-effective way to get 575 Corvette-crushing horsepower out of your supercharged 2003-2004 SVT Cobra? SLP®’s new 575-HP PerformancePac™ comprises a group of jointly engineered induction, exhaust, and engine-management components, all of which work together to significantly improve performance without adversely affecting drivability. No other manufacturer offers as comprehensive a package!

This package includes the following items:
2.80" Supercharger Pulley (M10002)
Supercharger-Pulley Tool (M10003)
Supercharger Belt (M10005)
95mm Mass-Air Meter with High-Flow Air Filter (M23000)
1 3/4" Coated Long-Tube Headers (M30002)
X-Pipe Short Assembly with High-Flow Catalytic Converters (M31034)
Loud Mouth™ Modular Cat-Back Exhaust System (M31006)
DiabloSport II Programmer with Multi-Stage SLP Custom Tuning (M27000T)

Save $100 over the cost of buying the parts individually!


What makes SLP’s PerformancePac the ultimate Cobra upgrade?
It’s significantly less expensive than aftermarket supercharger kits, none of which includes the level of equipment found in the SLP PerformancePac.

Brand "K" Twin-Screw Kit: 3799.00
Brand "P" Centrifugal Kit: 3400.00
SLP PerformancePac: 2659.95 (#M31051) or 2719.95 (#M31050)

All included parts are designed for an easy, bolt-on installation.
Unlike a centrifugal-blower conversion, the SLP PerformancePac causes no loss of low-end torque. In fact, torque output is dramatically enhanced throughout the rev range (400 lb.-ft. available at 2400 rpm, 500+ lb.-ft. available at 3200 rpm).
All SLP exhaust parts are hand-built from 100 percent stainless steel and covered by a limited lifetime warranty.
Headers feature a standard aluminum-ceramic performance coating to keep heat in, exhaust velocity up, and under-hood temperatures down.
X-pipes employ SLP’s exclusive five-piece modular design, making it possible to switch between cats and race pipes in a matter of minutes.
SLP’s custom PCM programs were developed over hundreds of hours of grueling in-house dyno testing. Our engineers sweated the details so you don’t have to.
Jointly developed components yield optimum performance and reliability. Why experiment with parts combinations? The SLP PerformancePac takes the guesswork out of building safe, consistent power.

Are those SLP's claimed numbers of the kit? They sound quite inflated. Headers, mid pipe, exhaust, pulley, CAI, and program doesn't sound like enough to get to 575 RWHP. The stock eaton doesn't have the efficiency to put down those kind of numbers in completely stock form. With a ported throttle body and ported blower, maybe.

If that kit can really do what it says, then way to go SLP. Now, if they could just make the cat back sound a little better, that would be a popular upgrade. But, I think those numbers may be a bit over stated...unless they are stating block horse power. That would seem a little more realistic as that would put the RWHP at roughly 490.

Oh, disclaimer. I'm not trying to bash you at all. It is jus those numbers sound too high for the mods. But, 480-490 RWHP for $2500 is not all that bad of a deal.
