I drive alot with my type s (about 1.5k/mo) , I was wondering what if I add headers to my car, how much would it make a diff if any ?

I may improve gas mileage. My CAI may have increased not dcreased MPG numbers!

------------------
Black, Ebony, 3.2 CL Type-S, NAV.
- 3M clear bra, by Stonguard (full front bumper, and side mirrors, and partial hood)
- Acura Spoiler, Moonroof visor
- Splash guards, Winter mats, Trunk liner
- Valentine V1 Radar Locator
- HELMS Service Manual
- PIAA 19169 road lamps
- 03/19/01: Injen Polished CAI
- 04/10/01: 235/40/18 NITTO 555 on 18x7.5 Koing Imagine in Silver with wheels locks

 

If you stick your foot in it, you will pay the piper.

If you drive at the same speed, you might acutally gain some gas mileage. The gas moves easier in the Comptech header, this reduces gas/energy losses. The CAI and headers should give you better mileage when driving easy.

(just my opinion)

• Mud guards
• Wheel locks
• Toyo T1S 235/45ZR17-97W* Proxies on 17x8" SSR Competition wheels (48lbs less than stock)
• Kevlar/SS Brake lines ordered
• Comptech headers & sways ordered
• Silver AEM CAI ready
• 6 coats of Zaino magic

 

I get on it all the time with headers (I did it before getting them too) and haven't noticed any decrease. My all time record for gas mileage (near 35mpg highway) came AFTER getting the headers and was when driving slowly (65mph). Previous to the headers my best highway gas mileage was about 32mpg so I agree that if you keep your foot out of it, you may even see a ***slight*** increase in mileage. I don't notice it being any worse with a leadfoot though.

just my .02

The headers give you BETTER gas mileage. My highway is around 33-36mpg driving around 75-80.
