hey there i am... the pipe lost a little on the low end over the pipe i had before that (homemade expansion) but it screams on the top now, though i feel like my engine doesnt rev up enough to really maximize the potential of the pipe.
i love the look, sound and performance of it though. it was a little hard mounting it to the flange on the head because the diameter is pretty big but with a grinder, a cheap HF 90 amp welder and a little patience it can be done.
