Not sure if they fixed the issue or if it was something isolated with my setup. I am running a Cobra downpipe again now but with a stock turbo manifold this time around.

I am purchasing a S13 Coupe as we speak. I think this is the culprit to the strange harmonics I am getting from under the car. Its related to RPM (2500-3200) in every gear. I see clearance around the firewall and Cobra DP but I haven't looked closely at the relation to the trans housing. I am running the stock mani with GTX2867R turbo btw. Any specific area to look for?
