we tried that a long time ago, running bills pipes with the stock silencer. it quietened it down alot compared to the bill's silencers and gave it this pretty unique sound. but it didnt help the power any. if anything it kinda felt like it took alot of the topend power away and gave it a smoother like powerband. I guess cause the stock silencers have this weird baffel system in there at the beginning of the muffler section.
