All tuners, whether they own a Japanese, German, American, or an Exotic, love power mods. Here I rank the best power mods that are somewhat affordable. Things like turbos and other forced induction methods are not included due to how pricey they tend to be.
1
ECU tune. When done by a professional, an ECU tune can DRAMATICALLY increase horsepower fairly simply and easily. The results are even more drastic if you already have some sort of forced induction installed on your car.
2
A4TRMRKT exhaust! Not only do aftermarket exhausts sound a heck of a lot better than stock exhausts, they can add 10+ Hp to your car by releasing back pressure and letting the engine breathe properly. You can find a whole bunch of these exhausts on our website a4trmrkt.com
3
Cold air intakes take in colder, more denser air therefore increasing your engine's performance.
4
Headers allow your car to breath better as well. Be were though as they are illegal in some states.
5
Catalytic Converter delete. Although VERY ILLEGAL in places where emissions are checked, deleting your cats let your car breath the best. Catalytic Converters filter out all the unclean exhaust fumes from your engine, but it is essentially one big filter that slows your car down. Think of it like this, you are running a race and the catalytic converter is like you having your hand covered over your mouth while running. It makes it harder for you to not only breathe in but it also makes it a lot harder for you to exhale. When you remove these cats you are taking your hand off your mouth allowing your car to have a completely clear exit for fumes. Oh yeah and it also lets your car spit flames!!
