03 Cobra - New Port with Numbers!!

Stage 3 Port with Plenum and TB Ported, 2.93 Upper Pulley, Weld In Mufflers and STOCK midpipe...yes STOCK midpipe

Car made 494/470 with 19* of total timing and a SAFE 11.7-11.3 A/F.

The old Port Designs, with a 2.8 Upper, O/R X Pipe, and Catback made 486/462.....this new port is WICKED.

It could have easily cleared 500, but you know me....keep it safe.

Add a good midpipe and it would make over 500 EASY as is
