Well in order to pass inspection they wanted me to replace the gasket at the exhaust flange after the cat and before the muffler. Well as usualthe nuts snapped off and drilling and pounding those super hardened studs out just wasn't happening. SO I ordered a Summit muffler and some clamps. I already had the 3 inch pipe. Now I figured that since the pipe in front of the muffler was 3 inch the one coming out of the muffler would be too. WRONG. Why does GM do these things? So I needed to find a correct coupler. So another order to Summit. Could have gotten it local once I found the part number. But the cost was more local for the coupler and clamps than Summit wit the shipping for the same darn thing. Pretty happy since that trash can of a muffler weighed a ton. And it does seem to have more power now. So good all around.
