Habitual Line Stepper
This might be a redundant question thats been asked before, but is it bad to run open downpipe on a stock twins setup? Is it bad for the valves? Open to all opinions.
All the backpressure is between the turbine and the exhaust side of the head, the DP isn't really a player in that at all.Thanks, like I said, just a hypothetical situation, Im thinking of the backpressure and if would damage the motor internally at all, warped valves, etc..
