I have a 2007 Scion Tc and I want to run the exhaust out the sides of the front bumper. I have a Megan racing 4-2-1 header and I was gonna run a small pipe after the header bolts on and have someone make a custom y-pipe, then run 2.5 or 3” straight pipe out each side of the bumper. Would it be loud, I’m in South Carolina so I have no inspection. And my Scion isn’t turboed
