LT Headers

Are there any problems with installing LT headers and leaving it open headers? Other than the noise of course

You will burn gas like it's cool. And you will smell gas while you're driving. I did it for like a week before I finally got time to put the y-pipe on, and my O2s still work fine. But I would recommend changing them anyways for routine maintenance.

With the O2 sensors in the collectors, running open headers will most likely result in the engine running pig rich, because the backwash of fresh air causes the sensors to report a lean condition. If you are running an open loop tune, that obviously would negate this problem.

Myth. Has nothing to do with performance or how the engine runs.

correct sir. I run open headers after the y pipe all the time(e cutout). Love the sound. No loss of power.

Thanks for all the info. So I'm guessing if I run some pipe a little ways out from the collector I won't run into the running rich problem? I mean my car isn't my daily driver so honestly I'm just looking to make it the loudest possible. For some reason I like being obnoxiously loud

sounds like a stupid reason for exhaust.

Just throw and x pipe on there and dump it before the axle. Otherwise its going to be very loud inside the cabin.

Than if its way too loud you could always throw on some bullets.

I would not run straight headers. In case you've never heard or driven a car with open headers, it becomes unbearably loud and annoying after a while. Like posted above, i would at least dump it right before the axle.

If you want it to be loud and sound good, I'd recommend true duals with an x pipe crossover. you can run them with no cats or mufflers, if you still want to be obnoxious.

Eh, not going to debate it, but I dout back pressure has anything to do with it.
