[Double Venom]

As a builder for more years than ill admit , we've been using different mufflers for at least 30+ years. Dyno'd many times from CARB'd 302's thru stroked 427's Minimum HP gains over CR's stock pipes is: 42 to 48 HP. EVERYMOTOR UP in Cubes was exponentially more!

Forget the "Band Aid" repairs, forget about the money you wasted on "Jet-Hot", CHANGE THE MUFFLERS, richen up your fuel by 2-5 percent and cruise very Happily ever after!
( don't believe me? DYNO your "Little Snake". )

(IF YOUR PROPERLY TUNED ADD 1-2 degrees in timing!)
PS. We did and still "did" use lifetime warranty Bullits from J.C. Whitney, (build by Arizona competition Exhauts) Never had to warranty one yet! $30.00 a side!
