Alright so i kno this is a common post but i just cant find everything i want. Im wondering the best hci for my 94 gt which is mostly street and a lil bit of strip. I was lookin at the trick flow top end kit, but it seems a bit pricey and i was wondering if there was anything cheaper but still good?? Also should i put longtube headers on my x pipe or do this mod first? and please include price and power upgrades if u can! anything will help thanks!
