i have seen many trucks using the buku exhaust. The main reason why it's so good is because it is an adjustable pipe meaning on the end of the exhaust there is a little bex bolt that you can tighten or loosen. Also, if you take the whole end of it off, you can use different little cones inside of the exhaust, each cone works better with different engines and tunes. The pipe supposedly works very well with all big blocks, but i have never owned one.
