well i got a resonator installed today (welded on) and i think than the scales where suppose to go with the open slit facing back but the guy installed it with the open slits facing forward(resistance)?
does it make a difference. if so will a\effect anything.?

 

that looks correct to me... I installed a glasspack with a open 2.5"pipe leading to infront of the RR tire and bolongna cut..but mine had like a perforated insides, it looks like that one has fins inside..

Look under the car and see if it has a INLET or IN and OUT on it...it should if it is directional.

 

well on the ct back it was bacwards as to how the guy welded it. but he kept insisting. will this effect anything.?

 

^ do what man?? didnt quite get that...what do u mean by ct? it does look installed backwards but it should really have a stamp on 2 spots sayin IN and OUT or something...

if it doesnt..then it is either universal or you Need to look at the instruction paper it came with and see what it says...
