I am soon going to purchase a 3 inch exhaust system. With the exception of sound, is there really any difference between the systems?
Which has the best fit and finish?
Which makes most power?
Which sounds the best?
Thanks,
SST
I am in process of purchasing a 99 GTS. I am considering K&N, smooth tubes, high flow cats and cat back system. How much power should I expect and do you think work the time and money.
I additionally am considering headers but do plan to drive the car frequently. Same question as above...
