I am extremely happy with my Rinehart True Dual system. Everything I was expecting. I would highly recomend them to anyone without a stereo system. And if you are riding behind me, just turn your volume up.
I HAVE RINEHARTS ON MY SG AND THEY ARE WAY LOUDER THAN THE BASSANI POWER CURVE AND SLIP ONS THAT I HAD ON MY RKC. AS FOR THE PERFORMANCE BAFFLES, I SPOKE WITH BUB BEFORE I BOUGHT THEM AND THEY SAID THE PERFORMANCE BAFFLES WERE QUIETER THAN STOCK. THEY ARE CHOKED DOWN A BIT AT EXIT GIVING MORE BACK PRESSURE FOR A LITTLE MORE BOTTOM END GRUNT.
