i recently bought some obxV2 headers designed for a 02-03 and put them on my car (4th gen) last week. the instal wasnt to bad but just make sure u have patience and a grinder :laugh:.
My exhaust set up is simple. Greddy sp2, 2.5 test pipe and obxV2 headers
enjoy
PS: im not s/c the whining noise u hear is my alternator. i have a new one but ive been to lazy to change it
