I'm with Dave on this one. I could give 2 shits what Joe blow can do at his local swamp track with these pipes. If you pick up 2 tenths from a pipe change, you weren't tuned properly in the first place IMO or just made a better run. I want to see builders use these, test 'em, and get some numbers out.
But I'll finally be graduating and getting a job, so $700 doesn't sound so bad anymore
