The Two-Valve 4.6 participant in our test belongs to Reyes JR De La Cruz. The '02 GT actually is new to Reyes (he acquired it just before our test date), with 91,470 miles on its virginal Two-Valve powerplant. Baseline power and torque for the New Edge came in at 231.96 hp and 268.10 lb-ft.

As K&N CAI's go, installation...
As K&N CAI's go, installation becomes a little more involved with each late-model Mustang platform. This New Edge system requires more assembly than the Fox piece, but its fitment is equally as clean, and it definitely promotes a much smoother air path than the restrictive OEM tube.
Two-Valve 4.6s are fitted...
Two-Valve 4.6s are fitted with 65mm throttle bodies (top). BBK enlarges the opening of its replacement piece to 70 mm (a bolt-on 75mm unit also is available).
Just as we did for the Fox...
Just as we did for the Fox throttle body, the plenum's bore on Reyes' 4.6 is enlarged to match the 70mm BBK we're installing.
As a general rule, replacing...
As a general rule, replacing both throttle body and plenum is the more-popular upgrade for stock Two-Valves. We're taking the smaller route for the sake of parts consistency. However, BBK's all-in-one 78mm unit is a direct swap that makes good steam.
Like the Fox 'Stangs, '96-'04...
Like the Fox 'Stangs, '96-'04 (SN-95/New Edge) Ponies also sport a foursome of super-restrictive catalytic converters.
Taking down the OEM exhaust...
Taking down the OEM exhaust on Reyes' '02 is also a cut-the-tails proposition. GTR's Jose Serrano handles this removal, using liberal dose of WD-40 to help dislodge the stock mufflers from their hangers.
DynoMax's Two-Valve 4.6-liter...
DynoMax's Two-Valve 4.6-liter 2-1/2-inch after-cat system features the company's polished Ultra Flo welded mufflers. The upgrades bolt on without drama and sound great.
Aligning tailpipes (polished,...
Aligning tailpipes (polished, 3-inch stainless-steel tails are included with the DynoMax Two-Valve system) is one of the final--and most challenging--aspect of an after-cat installation. While the pipes for our New Edge mimics the factory tailpipe routing, two people are necessary to set the tails perfectly in the rear-bumper cutouts.
