Waiting list?
Hey all,
I'm thinking of disconnecting the exhaust line just in front of the 2nd cat (or resonator box...looks the same these days) just in front of the center differential. I'd like to see if there are any performance gains from the reduced backpressure. Everything I understand about a turbo says that the great the d/p across the turbine, the faster it spools the compressor wheel, therefor quicker response.
My question is with less backpressure, I should get faster flow through upstream cat. Will this affect the upstream cat at all? I know it won't hurt exhaust temps as the sensor is upstream of the disconnect point. Just concerned that I might fry my cat. Don't know enough about them to be sure. I'm heading out in about an hour so any response would be appreciated.
Assuming I can disconnect with no issues, I do know to drive the car for a bit prior to realizing any gains, as the ecu will need to adjust.
Regards,
Scott
