Looking at hooking up some new pipes on my '98 Roadliner. I am considering the Hard Krome 3" Res Techs, seems that the 3" Big Straights are aggressively loud and the cops around here have a low tolerance for loud pipes. I do want the new pipes to louder than stock. I am concerned that the Res Techs will scrape and that they may not be that much louder than stock pipes. Considering the Cobra Speedster Slashdowns as well.
