I'm cooking up an idea about going total sleeper on the cressida using the stock 2.5inch Catback mated to the Straight 3inch downpipe going to the turbo elbow with the internal wastegate welded shut..
I drill a hole pre turbo on the manifold, and run a pipe to a external wastegate from there.
My reason for doing this is the constant drone of the 3inch exhaust. You think if I'm dumping to external air, I still need a full 3inch setup? I'm thinking the 2.5 should be enough if the internal wastegate is closed..
Give me some input on this.
