Right now im in the market doing some research on what kind of 4-2-1 header I wanna buy.. I have a 98 Prelude (non SH).. I have installed an AEM cold air intake.. I lowered my car 1.5in... And have 18s on... I wanna get a header that I not going to bottom end on...and get some good gains.. and looking to spend about $3-500.. I've looked in to Greddy and DC sport. Also how much difference is the stainless steel vs. the ceramic coat? meaning gains and noise wise...lemme know.
