If you have a modded 370z, look here

megalapagas

Test Pipes, Exhaust with Silicone post maf tubes and K&N Drops = Beast....It woukd be better if I was tuned but can't advise on that since I haven't done that mod but if your looking for serious power like 1Slow370 said look intos the forced induction section. I too myself asked these questions and was refered to the search button and actually they're right. SO MANY THREADS ON HERE via N/A mods and ESPECIALLY Boosted Review Threads. Welcome Op
