So, I went from a UPR O/R X to a brand new UPR catted mid. Shortly after putting the catted mid on, the Cobra lost power, torque and throttle response. About half a day after the midpipe was installed, the Cobra was running fine. Car was running better with cats than without, until a couple hours after I installed the pipe.
I had the exhaust checked for leaks- two separate shops couldn't find anything, and I neither can I. Though I swear I hear a leak sometimes in parking garages and while passing parked cars, etc. Car was tuned with an SCT for the cats, and was tuned when it didnt have cats.
Im going to check the plugs, coil packs, cats and replace the fuel filter over the next few days. Any ideas? Manifolds? Car is basically stock- unpullied, with a spec clutch, borla stingers and k+n cai. Want to diagnose as much as possible this week, in the event that it ends up needing shop time
Thanks
