Adding a good x-pipe and a set of Magnapacks will give your car a sound similar to a race car. I have this combo and love it. Its nice to roll thru the center of town, rev the engine up and watch everybody snap their necks around trying to see where the sound is coming from. On a trip to the local drags a buddy of mine took his 35th Ann. supercharged Thunderchicken to the track to race my 97 GT 5spd. He has 2 chamber flows running thru a custom 3" system. When he ran down the track all you could hear is the whine of his superchager. When it was my turn all you could hear is the rumble of the magnapacks as I went thru the gears. You couldn't hear the sqeal of the tires or the chirps of the gear shifts. He posted a best of 10.007 @73mph in the 1/8 and I beat him running a best of 9.63 @ 79mph spinning in first and second gear with bald tires.
