Iv got a 2000 V6 3.8 mustang, with manual shirft, cold air intake, and flowmaster 40 already installed. It is in real good condition and am interested in making it better. Money is kind of tight so i need to stay cheap. First off, should i loose the cats or not. I never take it to the dealer, and i am able to do a lot of the work myself; lets say i do take em off, can i get the annoying 'service engine' light off? Iv heard of superchips, but i dont really know which one. I would like to take off the top speed, but still keep the same rev. limit. Also has anyone tried any adatives for the engine that really work well? Any oils? As far as physical looks, im into that also. Im looking for underglow LED's, maybe some strobes, or lighting devise that trigger at programable times and speeds. Heck id even try flame throwers! So if anyone has ANY suggestions, let me know, thanks guys!

P.s. I am an ebay person so if anyone see's a sale, let me know!

 

First off, to my knowledge, it is illegal for any street car in the US to run without cats, so that may be a problem. there are plug-in eliminators that will get rid of the check-engine light, but inspection could pose a problem if you are running an offroad exhaust system.
Also, the flame throwers are illegal, so you will have to deal with that issue as well.

As far as upgrades go, you dont mention what wheels you have on your car, but 2000 mustangs didnt come with, in my opinion, the best looking stock wheels (I know, i own a 2000). If i recall, the v6s came with the silver 3 spoke wheels. if you are at all inclined, you could upgrade in that area pretty easily. plus, ebay is a good place to find inexpensive wheels.
Other cheap appearence mods include a chin spoiler, door sils, interior stuff (shift *****, aluminum trim, etc.), and under-hood trim, like radiator covers, intake badges, and the like.

Good luck with the modifications! -Dan
