Banks headers and etal


Banks says they will add 85hp to my rv with a v10 engine. will it do it?


Sounds like bunk to me. I wonder if they will guarantee this in writing and include paying for 2 dynomometer pulls; both before and after header installation.


With just headers? LOL!!!

Headers with no other mods MAY give you 2-3% gain AT MOST. And I have doubts if you’ll notice anything with the V10.


Don’t forget the fire extinguisher.
