Most people will say, albeit begrudgingly, that it was the crotchety old school teachers who taught them the most. Now THAT sir, was an answer to my question! What the dozen or so guys before you, Cheese included, left out was some tiny morsel of knowledge-prior experience-reason why the pipes suck. Thankfully you have seen fit to offer a big mouthful of the stuff. Say I'm from the show-me state, doubting Thomas, what-ever. I'm not much for going by blind faith. I wonder how many of those dozen guys have had an actual experience with those pipes, as you have, and how many were just repeating what they've heard. You have most thoroughly answered my fairly simple question and I thank you for it. It seems a shame I had to piss off a dozen guys before I could get a REAL answer.
I don't know weather your phishing or not don't really care, but anybody with even minimal understanding of how shit works would realize whats going on, when 20 guys tell you a certain exhaust sucks, but really don't know why, and just for argument say only 10 of them actually used the system, and they say it makes less HP and TQ than stock, since on a tuned bike a open pipe generally makes the best power then going the other direction a pipe for whatever reason don't flow enough air is going to make the least power......although I don't know than man personally, J Cheeses reputation with tuning bikes is in maybe the top 3 in the country, and if he was closer he would have tuned my bike already, I would guess if he don't give someone a technical answer its probably cause he didn't feel like it, and for the record it was not in particular a (Voodoo) system I had it was a (M4) but I'm sure the result would have been the same, also for the record, no matter what pipe I would have used, I was pissed at myself for a long time cause the money and time I spent on all the (conventional) hop up stuff was money waisted, as I found out AT, (after turbo)
