I'm Awesome
green at this exhaust thing. You guys are good at this 1000 times over. I got 1991 gmc 5.7. Can I put Dynomax ultra flow muffler 17519 on my stock exhaust with cat still on?. I will there Be issues with dash engine lights?.. and how about the sound?. I know it’s gutless but want that extra sound , but not too much.
