OKAY it's official now, Copperkid and I just installed his CBE, he will write a full review in a few days. So far first impressions, not impressed with quality of welds, the expanded joint idea was not a good one, I only see the c-clamp style type attachements on cheap quality exhausts, I would have expected MUCH more from Racing Beat, say a spring system like what Tanabe uses. Now as for the Sound if you want QUIET this is as quiet as I've heard thus far.... well atleast it's QUIET after initial install, but we will know for sure in a week or so after the unit "breaks in" as my CorkSport did. so in conclusion, personally I would NOT purchase this exhaust for the $$$$ it costs, cuz of the quality of the welds and not a full polished unit and 2.75 ID pipe diameter, not that it matters, but for what you pay it REALLY should have been 3" ID. I'm glad I kept my Corksport, just the right amount of sound, not to loud not to quiet. but you decide, is the name worth 580 bucks??? OH and the tip doesn't even have lazer edging or some sort of logo plak.
