I run the loudmouth I's on my truck. If your gonna dump it, do it just over the axle. They are loud. Well, they arent too bad if you still have stock manifolds and cat convertors, but once those are gone its a whole different animal. For a while I was using two dynomax bullets to quiet it down some, but I missed the loudness and took those off. If money is a concern, go with just the bullets because you can buy two dynomax bullets for the cost of one loudmouth.
