I didnt want to start a new thread so im gonna throw this in here....i have a 5th gen lude 5spd....i got a v2...aem tru power pulleys...nology hot wires....denso iridium plugs. Im not plannin on gettin an exhuast, but i am interested in a header and a high flow cat. Ive seen some headers on ebay for like 80-150 bucks. Since im not gonna do an exhaust, but only a header and high flow cat, is it worth it saving up for a top of the line header, or will these no name headers be ok for me? Im jus looking for a more tuned and deeper sound...hopefully a header and high flow cat will give me that...im not that interested in power, but how much hp and sound wud i gain with a ebay header and a decent high flow cat?
