i may have gotten this the wrong way?
when i start the car(cold car), its loud as hell, but only smoke and warm air coming out of 1 pipe. after half a minute, i hear the exhaust valve opening, and smoke/heat starts to come out of the second pipe. does it just open halfway beacuse im idling? pretty confused about this, cause i have thought about doing that mod also.
