Nice start to your build thread! It's always a tough choice between performance or cosmetic mods and in what order! It seems to me you go for the performance stuff first like I did! It took me quite a while before I was doing any serious cosmetic stuff. I always said if it looks fast it HAS to be fast! I like the idea of high flow cats! They will really wake up the engine and sound level for sure, although they are pricy like you said! Wheels would be the next cosmetic thing I'd do and if you shop around you can find excellent deals on some nice wheels! Good luck which ever way you go and congrats on your build!
