I see, you want to give it to them with the DP's already on. Dam, if they are dropping the tranny do yourself a favor and slide em a $50 to install only the DP's during re-assembly & save the test pipes for later. They would be a REAL bitch to do with the tranny still on. Explain to them that with the main cats the car is still smog legal. Then you can swap the test pipes out yourself much more easily after you get the car back home. =)
