| im putting my car back to stock to trade it in so im selling a megan racing downpipe for $80 i only used it for like 10,000 miles, its like 2.5 sie piping, the stock is big at like 1.75-2 i think, i noticed a gain with it though better throttle response and top end speed, if you have intake, header and exhaust without high flow cat you will definately notice a gain with it, doesnt make the car that much louder either. |
