before and after

My dynoport has a killer midrange but it has supporting mods like ported cylinder flotek head mod an rad valve pwk 28mm carb.. I've ran the f7 very good mid range as well but didn't do well on a stock motor versus something like the toomey an fmf based twds a stock motor..
 
toomey runs good with a ported cylinder to just not as good as the dynoport or f7 same thing with the dmc.. always had a lil more bottom then the toomey but not enough to sway me away from the toomey is hands down best left bend pipe..

you say toomey is the best " left hand" pipe. in your signature you say "right hand bend". is that a personal preferance or is there anything better to a right hand bend pipe?
