VRSF Catless Downpipe BMW 328xi - Before and After

[@TNStories]

Are there more pops/burbles/cracks after the DP, or is it mostly the same as before? What component of the sound does the DP change most?

[@EthanReviewsGames]

TNStories I would say volume and maybe some more cracks and pops. However, with the n20 engine you’re really not gonna hear too many burbles and pops without a burble map tune. I’m getting bootmod3 which is well known to increase the burbles.

@@EthanReviewsGames i only have a downpipe with the b48 motor i have loud pops. With the oem exhaust.

Did you get any check engine light after the downpipe ?

[@danielsipac4650]

Quick question; it is illegal had one on california?

[@teemeaux3830]

does the hatless smell?

[@colecummins5738]

hey man, how was the install? i'm deciding between a VRSF catless and a Wagner tuning catless, lots of people said they had fitment issues with the VRSF?

[@projectf3075]

There were some minor fitment issues, mostly due to how the DP is clocked/turned. There isn't a bracket to align it like the ER downpipe. Just be very careful and check the alignment so you don't have leaks

any difference gain perfomance than stock?

[@EthanReviewsGames]

Surya Dirham yeah, a catless downpipe can add a significant amount of power when you combine it with a tune. And if you do get a downpipe you’re gonna want to get a tune anyways because it’ll throw up a check engine light because of the o2 sensors in the downpipe.

[@alecpajor6320]

I have a cutoff valve that I haven’t installed yet. I was wondering if the car feels too loud at times with the catless downpipe.i was thinking about getting that and a tune and throwing it all in at once Does it give you more drone/vibration up front?

[@mabskha7917]

Sounds like a diesel tractor on tick over

[@Gurbalert]

Is this down pipe with stock exhaust

[@andyesquivel6856]

Yeah

[@Vanillabean22]

How did you open the flap?

[@EthanReviewsGames]

TheCool Kid I’m assuming it’s just a feature of the jb4 piggy back tune he’s got installed.

[@EthanReviewsGames]

TheCool Kid pretty sure the flap opens when you put it into sport mode anyways
