I just ordered the ON3 67turbo for a 88 GT. My exhaust is H-pipe and Flowmaster 2 1/2. Do I have to change mufflers if yes what mufflers should I get. I would like to keep the same sound as the Flowmasters.
I'm not sure if that question was directed at me or not. I don't have On3 kit. My setup is stage1 Ponydown kit. Which had the open waste gate. But I got tired of that god awful noise fast, so I piped my back into the down pipe.Benefits of being quiet. But can't u hear the wastegate? If I recall correctly the on3 kit has it vented to the atmosphere
