Bob can confirm this but I spoke with a gentleman and SAAC this year and was told that he had a set of stainless pipes made by HRE....Bob may be able to confirm what he told me. I was told that where the collector meets the muffler their is no tapper down to the 1" or so pipe that goes through the muffler. This results in a dramatic backpressure and I was told that he gained 50hp with the HRE pipes.
