The doughnut gasket is blown on my Jeep, I was looking at it and the manifold studs look like they won't alow me to change it without just breaking off (very rusty) . I've had a set of headers I got with the Jeep, think I'm gonna go ahead and put them on. I was thinking of maybe a set of Purple Hornie header mufflers to go with them. Anybody got any suggestions? They're going on a stock 304. I wish I could hear what they sound like before I buy 'em. I want it to have some rumble.
