Ya we were one of the first ones to run a stack through the hood on the street, on our green twin turbo dmax many moons ago, its cool but is loud and turns your headliner black lol.
Any exhaust shop can cut the muffler and weld in a staight pipe cheap not sure what all the searching is for. Lb7 with a straight is loud but i love the sound. Also efi live w/lift pump and run 12s with it. We went 12.7 on a stock turbo lb7 with a shitty trans and 12.6@105 on a stock lmm.
