poor air flow can cause your motor to run sluggish
If your looking for raw open power than no. But you can't drive a vehicle on the roads with open headers. So it's mainly off-road trucks or high hp mud trucks that run open headers.
Valves may not open at proper time--engine may not run or run poorly
i would go with either DCsports headers or Megan racing headers. but both run pretty pricy
If the engine runs it will run very poorly. You may also take the risk of having a piston strike an open valve.
Headers help to maximize exhaust flow which allows your engine to run more smoothly and use less power per stroke. Because of this headers can improve fuel economy but the change is very small.
It can make the engine run so poorly that it seems like the transmission has problems.It can make the engine run so poorly that it seems like the transmission has problems.
Haiti's government run the country and poorly at that
poorly
No. It may run poorly but it will start and run.
Makes it hard to start and run poorly.
I would say it all depends on your intake and exhaust system. I run mine with stock headers, nismo duel rai and 60mm invidia n1 exhaust...runs great with stock headers.. remember, just because it is aftermarket does not mean better...
Yes, for everyone's ears. Additionally some motorcycles will not run as well without the backpressure and can run lean causing engine damage
