Is it bad to run open headers?
The valve STEM could bend because of the hot air. the valve face both intake and exhaust experience tremendous heat, but the exhaust stem is hotter from the gas exiting the port. and if reversion ( a true thing that can occur) happens it could char the exhasut valve)
But I relaized why when I drove with the Y pipe the car stuttered. because backpressure was so low that the computer didnt know what was going on was was learning the different exhaust flow.

show me one case of that happening. I ran open y pipe for 2 months...everyday, 75 miles one way to work and 75 miles back. 5 days a week and then the normal bullshit driving on the weekend, plus a few track runs. My mileage didn't even change.
