There is extremely little free power on a 99-04 GT. The factory squeezes it all out in stock configuration. Best first mods would be catback, shifter, sct livewire with custom tune, gears.
Well, I got it home today, and right away threw my 18"s and a shorty shifter handle on it. I have to say, I am very impressed with the car, the ride is awesome, the power is surprisingly good for a stock mustang, and the looks are just damn sexy lol. I can't wait to see what it feels like with gears in it, among other things.
Just an fyi the 18" bullits off a 06 GT are the wrong offset for your 04. DSG is the best mustang color ever, I miss that color.
Nice list, but a couple of points for your consideration: If you must get pullies, get Steeda or some other good quality Non-piggyback type. You may be able to save a few bucks by skipping the MM chassis brace package and only getting the MM full length subframe connectors (I'm not saying the package is a waste, just maybe a little overkill). Save some more bucks by skipping the maf and tube. +1 but imho, in order: shifter, gears, sct xcal2, catback.
Pics will have to wait till tomorrow, I'm on my way to have my Kenwood CD deck and Infinity Subwoofer installed. 04DSGGT- I know they are, I'm running some slimline wheel spacers to make it work, had 'em on my 87 with SN95 brakes for months with no issues. I just wish the wheels were wider, but I'll just have to move to some DD wheels in the future...
Not so light lol, I noticed a good difference between the stockers and the 18"s... On another note, Circuit City did a fantastic job swapping over my infinity, kenwood deck, and kenwood speakers. My car has awesome sound now, all professionally installed.
Is there an air silencer or something in the fender that I should get rid of? I catch the occasional reference in these 4.6 forums, and I know it was a thing to do on the 302s, so can someone fill me in. Also---I just heard clips of an SLP catback on a stock midpipe and headers, and all I can say is
