they seem to be quite big gm lovers, especially for older gm muscle cars, but i did some searching on youtube and liked nearly every car that i heard and even a older ford pickup with a 351 had them and sounded great. you can get universal mufflers from them. anyways, does anyone have any experience with these? i want to do exhaust on my truck, but still debating on what to do
