Can you Hear your ReCirc Dumper with Full Decat ??
 

My98 with Open neck DPipe & No Cats.
Now the car used to have an atmospheric dumper but i have switched to a Re-Circ, When you back off now you can here a fast Ker-Ching sort of noise coming from the Down Pipe Area. (thats the best way i can describe it ):D
I know that the Return pipe from the dump valve routes back into the Inlet pipe just infront of the Inlet side of the Turbo.

Is this noise Normal ?? Do others get it also ???

Thanks

Dean

yeap thats ok, take it you have aftermarket airfiter fitted wot you can here is the recirc dv dumping noise is coming through filter

You can hear recircs even on a standard set-up, much quieter than VTA tho.
