Slp pipes are extremely strong in the midrange. My 4mm stk cyl is an arm ripper. Although, it seems they come on a bit later than I expected. That may be due to my 35s. May perform better down low w stk carbs.
Slps actually come on later than I expected. Kinda upset about that...
Dune ported w 35s w a 4mm.
I'm gonna put on a 2into1 chariot intake and see if it helps it. Single 35
