I gained right at 40 rwhp with the CC pipes. I also added true merge collectors that may have skewed the results a bit too.
As the exuast travels down the muffler it's constantly "bouncing' off the angular augers. Just that fact that the exhaust is repeatedly "hitting" the spiral center section creates undue back pressure, ie; impingement.
