did the one who created this thread ever post again? i dont think hes ever comin back to this. but if you do i have a real idea!!!!!!!!
ok heres what you do:
1) cut off your h/x pipe and weld on a big rectagular box at the bottom of the header pipes, like a pro chamber but bigger (as close to the front as you can)
2) weld y pipes on your tail pipes,with 4 very small round/import mufflers in place of your old mufflers.
3)then weld anouther large rectangular box to those 4 import muffs
(still with me??)
4) fianlly weld as many 3/4 inch pipes as you can fit between the two rectagle boxes. im talking like 50! or maybee like (100 1/2 inch tubes)
and if that dont work THEN try the audio cd i dont know
ferarri engines have realy small pistons and a short stroke i think.
the v12s are like 3.0's
find a way to make a 4 stroke engine into a 2 stroke then maybe it would sound more like one.
