Holiday Sale. Limited stock still available.

Stainless down pipes for the S58 G8x M3 and M4. Tested and used in our own G80 M3 development car. More real exhaust sound and improved flow. If you're only going to make one exhaust modification, this should be the one.

We have integrated a mini cat inside the downpipe to keep them free flow but eliminate any CEL from being catless. Inside each downpipe is an O2 mini catalyst spacer that filters the air before it is tested by the lamba sensor, meaning the readings are clear as if a full catalytic converter is in place. Being inside the downpipe also eliminates the possibility of a CEL from delayed temperature response that an external O2 spacer can sometimes cause.

Sold by others for hundreds more.
