i live in CA land of the strict smog laws so right now i have 2.5 inch piping all the way from my o2 housing to mu muffler which is stock so its causing restriction. i was wondering if you guys knew where to get a good quality cutout that i can use to bypass the restriction of the stock muffler. im trying to not get a state ref ticket

you need to go get the flapper off the top of a MACK truck's stack and weld it onto your DP, you could put a spring on it so it only opens when you floor it
