I've decided with my 2010 my goal is to modify it to stock sea level performance. Since I'm at a lower altitude then 7000' I figure I need to add an actual 30-40HP. I figure I'll need a CAI, cat-back, and headers. On the headers I'm waiting until spring to see results people get from the various short and long tube. I'm guessing now that I'll have to go with longtubes to meet my goal. The only other thing that might help is tuning.
For a car guy I really hate living at high altitude  On the other hand everything else is awesome, especially since I bought my house in a non-emission county so long tubes are easy to justify. |
You might actually be ok with just intake/exhaust/shorties.
However, I'm also waiting to see how the shorties vs. longtubes turns out.
