Wondering if anyone has installed the Barron's big air kit themselves and how difficult it was and any complications as a result of the install? I'm looking for more rumble out of the pipes and wondering how This will affect the sound? Current set up is stock air box, fi2000r fuel management and cobra extra longs(baffled). Thinking of doing Ivan's reflash and Barron's kit. Not interested in true duals, too many stories of scraping and I like the looks of the cobras.
