Fixing to purchase a 2000 Royal Star Venture LE. Definitely want to upgrade Mufflers. I Love the sound of Monster Ovals from V&H but the price is quite staggering. Suggestions on a slip on that really changes the tone like the Monsters but much more affordable. LA Choppers sound good and look good, would like to hear what ya done. Are any modifications needed, what size, tuning needed, etc. Please let me know, Thanks
