Like I said I've never had anything much over stock before. I had a 318 in my barracuda that was modified it had a 340ish cam 360 heads and silvolite kb pistons it was straight piped wasnt that loud. Maybe our definitions of loud are different haha. The loudest vehicle I ever had was a 2.9 ford ranger it needed a muffler because it was rusty I took and had them cut the muffle off and put a piece of pipe in and it was unbearably loud
