What mods can you do?
Can the Plenum mod be done w/ the 'x'? Which spacer? Besides HP, cooler intake, does this effect the gas mileage in any way (less or more?)
Exhaust - dual exhaust set up - which sounds the most like the G35 coupes?
Headers? Do they make headers for the M35?
Intake -which intake has the best performance?
What types of HP increase can I expect overall with the plenum spacer and an exhaust?
