In general, I have not noticed a major difference in fuel consumption with the dual exhausts. If anything, it may go down as the motor will be running more efficiently with a less restrictive exhaust. One thing I would do, to preserve the quiet exhaust, is make sure they use stock-type mufflers (the big ones) and not those turbo deals. Turbos are loud and, IMHO, have no place on an Imperial. An H pipe would probably help balance out the sound, and give a bit of a power boost, too. > electrical system)..i mean > to say that when i turn the radio volume up the > buzzing sound can be heard > thru the radio( i mean it disrupts the radio)...the > sound only happens when > the driving or night-time light are on...the parking Could be a bad alternator, or bad wires. Basically, the headlights are loading up the alternator and causing it to buzz. A new alternator may fix the problem, especially if you go with a slightly higher current model. Otherwise, you can install a capacitor (at least 100uF, more if possible) across the power and ground terminals of the radio. The capacitor will shunt the noise to ground. ===== --Mike Pittinaro 'Tis Christmas again Have a happy holiday Imperially __________________________________________________ Do You Yahoo!?
