Well, if we are comparing bang for buck, let's break it down.
03 Cobra:
Cat-back 350
Intake- 150
Midpipe-150
Pulley-350
Tune-350
= $1,350 on a high average. These are more or less new parts. What kind of power level? Around 450 RWHP and around 470 RWTQ on AVERAGE. Just thought I'd point this out.
SB- The pullied Cobra list is old. Musclefan21 broke one of the records with his 11.34 @ 121.93 1.64 60ft in a full weight, pullied onyl cobra.
