How much they will give up(SLP tri-y:s)
Has someone good quess how much my currenr slp tri-y:s will lose horses.They have 1 5/8 primaries.
Pipemax will tell me that right size headers to my engine should have 1.75" primaries if they were tri-y design ,and 1 5/8" if 4 to 1 design.
I made also some backpressure measurements few year ago,at wot there was ~2.2psi backpressure(measured just after collector).Rest of exhaust is single 3"&dynomax muffler(no cat)
