HMMMM... I'm not sure which one I like best
The 350z stock airbox is ideal as it is a pressurized ram-air style intake with very unrestrictive piping. Oil filters such as K&N have caused the MAF to get oily so most people just leave the intake stock, and people that have bought intakes normally resell them a few days after they buy them. As for exhaust, the Injen is sick but the angled tips are ugly, hope the straight tips will produce as much power. Most of the clogged power of the Z is on the exhaust side. Nissan detuned the exhaust for better emissions ratings (Z is a LEV). High-flow cats and exhaust have netted over 20rwhp, but for that $1100, I'll save it for somethin else
