UPS came to my door at 6:00pm. Less than an hour later the conversion was done... YOU CAN'T BEAT THE CHANGE !!!... FOR THE MONEY YOU CAN'T DO A BETTER MOD !!!! My DAYTONA never felt the same. Its easier to smoke the tires wih ECS off (WAY EASIER). Full throtle accelertion off the line is not much better but the pull above 3000 RPM is definatly greater. I did not like the noticable power lag between shifts in the manual mode. (NOT NOTED AS OBJECTABLE BEFORE) The shift / power lag was much more pronounced with the exhaust mod. At WOT the car was a PIG, even more so than before. With the throttle at 80%+ the engine ROMPS. THE CHANGE IS VERY SIGINIFICANT FROM 3000 TO 4500 RPM. Off the line seems to have no differance in accelleration. The rumble of the EXHAST at idle is about the same. When you "KICK IT" the BOB's pipes make the car run more diftinctive.....a
