Bellows, let's talk about them. I had planned on running some for my inner stage pipes since my w/a is body mounted. After seeing the prices I'm now thinking normal rubber boots and some boost straps will be what I do. I'll spend the money on the bellows if I really need to, but I wouldn't mind spending that money on other things I need to finish this. My engine is mounted with poly mounts it shouldn't move too much.
