Installation Time:
60 minutes
Notes:
Remember the intake we just installed? Yeah-it had to come off to facilitate the header install. Additionally, cylinder number four's high-rise runner will contact the intake's heat shield, so you'll have to bend it a little-the heat shield that is. Most importantly, selecting a properly engineered header like Racing Beat's is crucial; with no flex piping or spring bolts in the Miata exhaust tract, construction has to be perfect, and we've actually seen poorly designed headers lose power over stock, in addition to not fitting properly.
Conclusion:
After four parts and nearly a 30whp gain, our Miata still barely cracks the 100whp mark...but is loads more fun to drive. Is it a Viper killer? Will it outrun a Vette? In the words of Marcellus Wallace: Not by a damn sight! But with its added power, the Miata will carve through a winding canyon road with ease. Throw some forced induction or juice into the mix, and you've got a recipe for a raw, low buck, real-wheel-driving experience not many cars can easily provide. Miatas are a dime a dozen, fly under the cop radar, and have been made into successful road race, time attack, and drift cars with little investment...only time will tell what's in store for ours!
