I have a 1991 5.0 LX, swapped for a 347 stroker, and it just seems incredibly loud. I have had multiple exhaust set ups on this car (all had shorty headers and an x pipe), and it seems like they are almost all the same loudness. I had a dump exhaust with mufflers, then I put on tailpipes, then I switched out the mufflers to other mufflers, but it seems like it is still just as loud. I have friends with v6 engines with no mufflers, and they are not nearly as loud as this. Even when I am just idling it’s hard to talk standing near the back of the car, when you can barely hear that they are on. Before I did the engine swap the car had a very mild cam in it, and it was somewhat loud but not as loud. But now that I have a street/strip cam it seems a little louder, but this car has been loud since the day I got it. Are these pushrod v8s just naturally that loud? Is there any set up that anyone knows of so that the car is quiet at idle but loud when driving? The mufflers are chambered so they should be doing something to quiet them down. I have started the car with open downpipes a few times and it is monstrously loud. I love loud cars, but it’s a little rough when you’re trying to leave early in the morning or talk to someone right next to you. Any help or info helps, thanks
