I am going to car boutique to get a K&N cleaner and I wanted to check some prices on exhaust systems. I was wondering the best setup for a 98 CSVT. I want it to be not very loud. I was looking for specific parts to make a complete exhaust like type of headers, pipes mufflers cats all the good stuff.

Also, I was wondering what is the best oil for this car, I am also getting ready to do an oil change.

One more question, for you stereo guys, do you need a cap to run a system in this car, or will the elec. system hold up fine. I had a BMW and I didn't need one, but I don't know for this car. Any advice will be greatly appreciated!

Thanks Chris
