I tried my best do search and look for the answer for my particular situation but wasn't able to find the info I need. Let me know if it has been asked before.
Currently my car has the MS CAI, and the RS dual muffler. It is nice and quiet, but I am in search for a little more power. The car is a weekend car that also autox and track, so it has to be very reliable, and has to be under 92db (local autox restriction).
- How many more HP can I expect to get with the RS mid pipe and header?
- How many more db will it likely go up by with my dual exhaust?
- How many more HP will I gain if I do the ECU refresh after this?
- What do I need to order? I assume I need the mid pipe, header (buying used from a friend), and some cable extensions for the O2 sensors?
Thanks a lot for your help, new to MX-5.
