are there any downsides to running a header with efi? on rb's website it notes that you shoudnt run one with it. https://www.nopistons.com/forums/pub...1047683561.gif

I haven't noticed any downside, and I haven't heard anything bad from anyone else running a header.
The only thing I could think of would be if you got the race header, and your car needed the O2 bung. |
o thats good i guess i'll get the rb header.......right now i have the downpipe and presilencer what would the header replace? just the downpipe?
|
on a stock motor, I know the header replaces the exhaust manifold and main cat, it should bolt to the presilencer
so I guess to answer your question, yes, it will replace the downpipe, but also the exhaust manifold (bolts to engine) |
yeah, I just did the same thing.. replaced the RB downpipe and stock mani with RB header.. power is almost the same, noise is a bit more... I just couldn't take the look of the exhaust mani anymore when the heatshields broke off.
