VRSF Downpipes before JB4??

blod5 · 11-04-2015, 04:38 AM

Have a 335i N54

The downpipes are getting fitted tomorrow

Already has a BMW performance exhaust

Literally just read something saying that if you do the downpipes before the JB4, the engine light will come on.

Is this true and can I get rid of it by eventually installing the JB4?

Yes your check engine light will come on. You can turn it off when you get the JB4.

Your car will be fine without it, you will just have a yellow light on your dash reminding you to get a jb4 or a dp fix.
