Ok i just got my turbo xs downpipe and racepipe installed lastweek and everything was all good so to speak (NO CEL). Over the past two days i had been hearing a gargling sound from the exhaust like it was coming from under the car somewhere in the middle. Today i go full throttle on a feeder and hear a loud pop come from the engine bay, now the car accelerates extremely slow and driving 60 seems to be pushing things, the exhaust is Unsually and much, much, more louder. There is no CEL on, if i had jack stands at my apt i would check under the car to check the downpipe test pipe connection. The upper portion of the downpipe connected to the turbo appears normal. There is was no visual, leaks, cracks, debris, in the engine bay.
