I know there is always a debate on this, but quickly...whats the HP improvement on a N/A new edge with LT headers being added to a car that already has 250rwhp (full intake (tb plenum)) and X pipe + catback? (my buddy wants LT's now that he saw mine) whats the HP improvement on my car with a KB blower and full bolt ons?

I'd say close to 400 rwhp. Wanna buy me one too? [8D]

Don't know the exact numbers but they are worth it

400 hp..hahah maybe more like an extra 20 hp over stock

try looking at what advertized hp numbers for 03-04 cobra exhaust looks it may give u a better idea, i'd expect 30-40 hp for the full exhaust
