Well just to let everyone know. I went with the Dynomax Super Turbo 3" I bought the slip-on reducer from the 4" to 3" ran 3" pipe to the mufflers and with the turn-downs angle down and out. What a world of difference. I rechecked the dB's on the car and it went from 103dB to 85dB at 50', I know the mufflers are new and will get some what louder after some use. But like I said a world of difference. Now I can enjoy the car, and when needed at the track can change out exhaust. Thanks for everyone's help.
