E-Cutout
anyone run a exhaust cutout before the o2 sensor, my o2 sensor is located behing the engine before the cat, but because of limited space and to make it most effective I plan to put the cutout in front of the engine off the topmount downpipe and dump it right next to the wastegate dump. will this be a problem? the motor will be tuned with the exhaust closed, but I figure we will have to tune a little richer to compensate for when its open.

Re: E-Cutout
I am thinking should just to add another bung before the cutout which could be use for tuning with the coutout open only, since I cannot run 2 wideband o2 daily, but one concern I have is the o2 sensor that is located before the cutout will either get too much oxygen from being too close to the opening, or burn up too quick from being too close to the turbo. but this would be used only during tuning so it may be a short term issue.
