    How Low Can You Go?How Low Can You Go?
    Lowering is high on the list of many people who want to improve the appearance of their car. If you want to lower your car with the coil springs, then replacing them with lowering springs is the way to go. But what if you want to lower your car and also make it handle better? If that’s your goal then consider coil-over shocks.
    Are Superchips Really Super?Are Superchips Really Super?
    Although most automobile manufacturers try to achieve a balance between performance and emissions when the ECU is programmed, in reality more power can be obtained when certain engine control parameters are changed. Aftermarket superchips are made to adjust parameters to increase engine power and torque. The superchip gives a “boost” to your vehicle’s...
    The consensus opinion among exhaust flow experts is that any V8 engine will benefit from a dual exhaust system with an H-pipe or X-pipe. H-pipes were first installed to quiet this exhaust noise.

    A few problems with band clamps not holding like they should. Muffler would rotate even when the clamp was fully tight, tacked welded two sides. Left side passenger outlet tube ended up very close to spare tire, still cleared. Removing old Flowmaster system and installing the new Magnaflow took about 11/2 hours on a truck lift/rack. Over all the stainless system ended up looking good. Now the sound! At idle low deep mellow sound. Light normal throttle, again deep mellow sound only louder. Will not brother neighbors. When hammered holy smokes, they know your coming. One problem with sound is at 63+ MPH a loud low pitched drone starts and stays. Solved the problem with stainless steel 6 inch round resonator, welded in. Remember this, all stainless steel metal is not the same, good, better, and best. Make sure the warranty states, life time warranty, not limited life time warranty. Just be sure! My aluminized Flowmaster lasted six years and were falling apart piece by piece., have pictures. Flowmaster warranty 3yrs. Bottom line the Magnaflow exhaust system looks good, including the stainless steel. Price is high, again warranty and stainless steel material makes the difference. Contact CARiD Steve Nagy for the best price on the internet. Hope this helps!
