Awesome guys, thanks! I will look into the Dinan tunes, and I'm not concerned about the CAI so much.
What about these?
1. Are all catless downpipes created equal? Can i buy the least expensive one? Do you have a recommendations? what size or brand?
2.. Can i buy the least expensive FMIC (intercooler). Which one will fit without any "cutting" (Direct fit). What FMIC do you guys recommend with cost being a factor?
anyone try this?
