I use a Top EFRA-9886 (#086) pipe with an Ultra MBX header, I'd use the Hyper header but the spring gasket is gone. I also use a bored out OS #20E carb so it seems to narrow the powerband and helps the bottom end some but the top end is insane. Any #068 or #053 pipe should do, but as for makng it sound deep I'm not sure, but possibly a dual chamber or CVEC 1/8 scale pipe might work.
