performance

Full stainless exhaust system won't cost the earth and shop around for an ecu remap.

you have a premium luxury car and you are trying to find cheap performance? those two categories do not mix. speed costs money. it costs more on a high end car.

Hey madmopar (nice name by the way what are you 12) Sorry buddy but you're wrong. Being able to figure out what changes that can be made to improve performance and do it yourself is the answer. It sounds like you just bring your car to someone else to do it for you. I'm on this site for suggestions from people that are interested in helping. Thanks for your help.

Thanks James. I just got the name of a reliable muffler shop that does work on cars like ours. I'll order the cold air system today. And, you're right there's nothing like doing the work yourself and the satisfaction follows every time you're in the drivers seat.
