BMW g20 330 catless downpipe + muffler delete

Hey everyone, just got my catless downpipe installed, as well as a muffler delete with y pipe. The exhaust sounds amazing and I would high recommend instead of getting an aftermarket exhaust. I have JB+ on the way also Would you guys recommend getting an MST intake, wondering if I would even be able to hear it because the exhaust is pretty loud now! Have a blessed day!

You'll defo hear the "wooshing" from the MST. When you lift off it's a proper loud woosh. Think 90's WRC wastegate chatter and you won't be far off

Definitely share some videos, I am looking at doing this too vs getting an exhaust system.

Warranty?

I'm not 100% certain but I think it will void warranty. You're deleting the catalytic converter which is a major emissions component. But if they don't see it when you bring your car in for service, you might be able to get away with it.

Honestly, I'd much prefer a downpipe with a high-flow cat on it. Can't drive cars with exhaust fumes anymore.

Oh wow, I had no idea you were on Bimmerpost lmao. I commented on the video a little while back. Ended up buying the exhaust myself with a big discount from an SD dealer.

I was wondering if your exhaust was a lot louder sometimes? I'm currently keeping the exhaust open with Bimmerlink, but it seems to vary a massive amount in volume regardless.

100%. too old to be driving around a car that makes the sounds that catless cars make with the horrible fumes. i'd prefer a high-flow cat as well.

If you guys want to hear what this sounds like, the F30 post has plenty of videos.

BMW 4cylinder turbos sound great with resignator removed. They are more poppy and have a great sound.

I'm good. My last car was a 350Z fully sponsored by HKS (11 years ago) with the twin turbo setup. The catless downpipes were fun, just couldn't stand the smell of the fumes.
