VRSF CATLESS Downpipe NO TUNE In Car REVIEW

does it increase power?

can you put in on a dyno before tune?

I just the same on my e90 N55 an I didn’t get an engine light, well worth it tho even with the smell you’ll feel the power big time

Yeah, you really need to add the injen sp, BM3 stage 2, and muffler delete, or replacement... keeping the resonator actually helps with that deeper rumble and more pronounced sound.

Hi what size wheels you have? J / offset . Als what size tires ?

Did you get rid of the smell?

Mine started to have white smoke after I installed mine

did you get the pops right away or did you have to what and is it in sport mode plus

im under extended warranty for my n55 e92 thinking about getting the downpipe should i?

Did you notice worse gas mileage after installing downpipe before the tune? Wondering if it causes car to run very rich.

How can I remove the check engine light regarding the downpipe/custom exhuast fabrications? Is there a way to remove the codding ONLY for the exhuast part and not the check engine entirely? Is there a sensory cap I cam plug in to trick the system?

PLEASE HELP 🙏🏼🙈

Have you gotten any weird spitting/rattle sound when idling or stopped at light? I just had mine installed and now thinking I should of bought new v clamps maybe not sure if a leak is causing it or is it just the raw sound of having no cats

would this cause any type of engine damage / bad fuel economy because of the no tune?

Is the code that it throws bad for the car because i wanna install but im still saving for tune license

Did you use 2 defoulers? One on the upstream and one on the downstream o2 sensors?

Did you upgrade your chargepipe?

what 02 spacers do you recommend? 535i F10 N55
