Profile: Pertronix, Inc. specializes in offering ignition products. Our ignitor II units sense the coil current level and use a powerful micro controller to adjust the dwell. Variable dwell helps to maintain peak energy throughout the entire RPM range. It develops up to 4 times more energy between 3000 and 5000 RPM than standard ignition systems. The RPM performance is improved when used with the Flame-Thrower™ II super low resistance (0.6 ohms) 45,000 volt coil. HI-FLO glasspack mufflers features heavy steel core design and has six rows of louvers for reduced restriction & better sound absorption. Long strand sound absorption material is used for increased muffler life. Hi-Flo oval mufflers are ideal where ground or axle clearance is limited. The brands we offer include Ignitor™, Flame-Thrower™, Second-Strike™, Patriot Exhaust™, Thunderbird Exhaust™, Smithy's™, Doug's Headers™.
