Tired of your factory F355 headers going out? Want something that sounds better? Want 17 more horsepower at the wheel?
NAPerformance has found the solution. They are making improved exhaust manifolds for the F355 that will solve the reliability problems, make your F355 sound much better, and increase your horsepower! Not to mention they are much easier to install then factory manifolds.NAPerformance manifolds comes with a lifetime warranty!
I've included some pictures of the stock manifolds next to the NAPerformance manifolds.
We dyno'd a peak gain of 15whp and showed 25whp gains on certain RPM's compared to stock. The low-end of the F355 was vastly changed, it actually has much more torque and power on the low end to play with. The mid-range torque and hp were also greatly increased and whenever the stock F355 gets close to redline it it starts to lose momentum. Our test car with F355 manifolds dyno'd 16whp more at redline.
Manifolds come with Jet-Hot ceramic coating.
Please specify whether your car is a 95(2.7) or 96-99(5.2) when ordering. |
