even hacked up the stock exhaust is very heavy. your best beat is to remove the exuhst from the axle back and have a down tub made that you can bolt to the mid pipe. do not run with the stock mid pipe only. you need a down tub to move the hot air as far under the car into the air stream as you can or it will pool under the bumper as the mid pipe is up turned where it joins the exhaust at the rear axel. ask me how i know.
