well you had all that air coming in and probably not enough flow mods to get it out...example: Intake, Rockers, Smaller Pulley...and only a U-Bend Deleted?
Probably hated you...lol
I also said i had headers and a custom cat back 2.5 all the way no resonator and had a cherry bomb muffler ???? not enough outlet how could i do anymore besides a cut out or a 3 in down pipe
