    Default what do you think

    Where should I do first, exhaust or air intake? I want good sound and performance with keeping it in the carb legal for california.

    Thumbs up

    I think I would go with the "air intake" first. Most people go for the exhaust first, but I bet they would be about the same cost which ever way you go. Good luck!

    i did intake first. but thing to remember is bringing more air in and having it not going anywhere is not always good. kinda like taking a funnel big end on one side and small on other. put liquid in the big end and takes forever to get through the smaller hole. same goes for you motor. more air in takes for ever to get per say. thats why if you do one you need to do other to get best performance.

    I got the intake first as well. I definitely noticed a difference in performance with the intake, but no fuel mileage benefits to speak of. Once I got the exhaust, I noticed even more performance improvements and at least one extra mile per gallon. Like Black Jack said, you can't experience the full benefits of one without the other.
