Yes. My user name on mustangforums is "Diabolical!", but it used to be "nineinchnail1024". I've been on there for a few years with a couple thousand posts, but I post FAR less frequently now than I used to. I used to post a ton of how-to's back when I installed my supercharger, clutch, driveshaft, etc.

a car like that with super stiff suspension, super loud exhaust, so low it scrapes everywhere, gets a little stressful to drive every day lol
that and since edmunds.com built it i really didnt wanna change the apperance too much from how they had it cuz then it wouldmake it harder to believe that its the same car they built. part of the fun of mustangs IMO is that there such much you can do to them visually. so, idk for my next car i think either ill get a GT and make it how I want it to look and perform or ill just get the blackjack to match my truck cuz i love how they look already
and i miss the mustang so much sometimes lol

alright guys sorry to butt in. How can you tell if your cats are affecting performance? I'm not getting great mileage. Even if the stock cats are ok would I notice a significant mpg difference if i sprung for some high flow cats?

i done the same thing to my 06 w/ 4.6 cut the cats out and it ran about the same as far as i could tell! BUT i bought the E3 spark plugs and all i can say is WOW!! truck ran AWESOME after the change!! i got a custom tune with an HP tuner and on my first pull it banged out in first gear!! i was like WTF then the same thing the second pull. I was still like WTF lol, then the computer corrected the problem and never looked back lol. i guess the ECU was in SHOCK!! trucks runs and sounds AWESOME, now to the 4.30 gears S&B intake, and some long tubes
