Hi guys, I appreciate that this is a topic that's been done to death but I have a 350z 05 anniversary model (revup) and use the car for road use only. Going with tdx2 exhaust, art pipes, 5/16 plenum, mrev2 plenum before the uprev. I'm not expecting anything really in gains as I know unless you're going Fi then then that's the best route for gains, just can't afford that. What I don't want to do though after spending the money on those mods is actually lose power?! Which I've heard has happened to people. So basically just getting the general consensus that these mods shouldn't effect the car in a negative way?
