Hello! Thanks for checking out my page, I have been active on the Sentra forums since 2003 ( MarkSpecV ). I tested and dyno'd the XS Power 4-1 Header for SS Autochrome/XS Power. From there on, I passed along the info. and was offered to run Group Buys on the forums. I enjoy helping other owners out and not break the bank! You don't have to buy the Big Name Brands to have the same performance results. Save your few hundred and buy other mods :) The 4-1 XS Power header has been a Great, Proven 4-1 Header througthout the years. I have sold nearly 300, on the fourms/ebay, feel free to view my feedback. Most dyno +12whp from 3k - redline. Has BOTH o2 bungs and w/ an o2 spacer makes an easy install. I sell the o2 spacers also, they just thread right in and no SES Light =)Contact me for discounted pricing on Turbos,Intercoolers,Downpipes, or anything from www.ssautochrome.comFeel free to message any questions!Below are a couple of links..
