my exhaust is completly stock right now and i want to fix that. Im thinking im just gonna buy and new downpipe, and put some sort of exhaust bypass on. And leave the downpipe back stock. and when im about to race or something turn on the bypass. What would be the best downpipe for this/what downpipes are the best? thanks

Any downpipe from a vendor. Just make sure it has a flange to bolt up to your swingvalve of choice. Have the DP welded to a Y-pipe, and then to the factory exhaust. Install the cutout on the open end. Simple as that.
