I've been told their headers are excellent, and am ordering one. I dont know the diff between the road Race header and the header with the Collector/presilencer.... im sure the collector is a little restictive, and am not worried about Noise, will the road race header bolt up, or do i have to buy the one with collector... I know Lots of you Have the RB header, so please let me know which one you All bought, And what they did for You!!??

The collected header does just that...it collects both primaries into one pipe..which leads into the presilencer. The road race header ends with the two primaries being uncollected...meaning 2 seperate pieces of pipe. This is mostly used for a true dual configuration, or in making a custom collector.
