I keep this car on the street 99% of the time with an occasional jaunt down the track when I do a track day, I have the exhaust assembled with header collector style joints in several key places to make the exhaust system fairly easy to remove. I run down the track with open headers and no exhaust system on the car beyond the collectors. That said, since I am not seeking every ounce of performance on the street, I opted for straight 3" exhaust with no crossover pipe of any kind. I also like the look and sound with the factory style chrome tips. Personal preference. I have run dumps before the axle, but all it does is stir up dust everywhere I go.. LoL..
