Inside the muffler a y pipe was installed with a QTP valve. Love this mod because you adjust the sound to stock to wild.
my perference is 1/8 to 1/4 open via remote transmitter. the video only show full open to close. You can clearly see the better flow open vs closed by the steam out the tail pipes

Did you keep the second set of converters up front?

i went with american racing headers it comes with cats and pipes to hook-up to stock muffler for a sedan or coupe. I prefer them over others best built header in my opinion

After you are done are you going to put the car on the dyno?

Dyno yes! but will street tune it first without getting on the hammer, but the problem is snow. Hard to believe we got snow given the prior years. last year same time people were in bikini's and short
