Just ordered my Kiddracing RMF header. It is damn near impossible to find a real one, so yeah...
Anyway.
Should I get a 2.25" high flow Magnaflow CAT or 2.5" for the best performance for now.
My engine is 100% stock for now, but I do know I'm going with 2.25" custom piping from the CAT to the exhaust.
So it would be...
2.25" Narrow header pipe > 2.5" collector > 2.25 or 2.5" CAT > 2.25" piping > 2.5" exhaust
The bolded lettering would eventually turn to 2.5" for sure, once I build the head and bump compression.
I have a B18C1.
