Has anyone used theses mufflers, how are they holding up? I use Lenny Blakes Rum Runners currently but looking for another option just to try. I've pm'd the guy with the ones above but no reply. Not complaining at all I understand everyone is busy.
I have been making add on mufflers for all my pipes and I found this design to work the best for me. Gets me under the 80db limit that Europe has and has in most of my boats improved performance. Not to mention that they run whisper quiet. It takes some getting used to as all you can hear is the air rushing into the carbs but the benefits other than making noise limit are worth it. And anyone who was at the Vegas Nats will tell you, you could not hear my JAE 21 boat run but a perfect 1600 points says it was. I make most from everyday items like arisoll cans, Axe body spray etc. and machine a inner re-enforcing sleeve to give the clamp somewhere to grab without distorting the can. When I need a custom size i use aluminum pipe and turn it down to loose weight. Not for everyone but just showing what you can do. The first on my C hydro is a Old Spice deodorant can with a sleeve and on one of my A hydro's a machined and press fit one.
