Hi all, have to say sorry first up. This topic may have been discussed to death already. I am having some serious conflict of information about part and its compatibility. I am look at the BMW performance Exhaust for my 2011 E90 323i. The part number is 18407646693 and was wondering if this bad boy will fit my car. Or if not I am up for some advice on what exhaust others have found to be good and ofcause sounds tremendously awesome... Man thanks heaps in advance for any help.

To my understanding the exhaust muffler fits universally just a matter of how it sounds like. It fits all except the 335i.

Why don't you look up the compatibility on Realoem?

[Cyclopx]

Funnily enough I did look that part up but it mentioned that it will fit a 323i USA which in my noobness further confused the crap out of me. I am unsure of what is the different between USA 323i to eur 323i.

I had the PE installed early this year. The only complaint I have is it's not loud enough. What we get in Australia is just the muffler component, where in the U.S. you get the muffler and the silencer delete Y-pipe which makes it loud AF.

Go Vanguard... plenty loud

Eisenmann race will be loud

[Cyclopx]

Thanks man. I will research into all of these suggestion. Eisenmann was crazy expensive. So still tossing. Waiting for the insurance company to pay me out so that I can make a decision.

What do you all think about custom exhaust? Has anyone done one? How did it sound? And any recommendation on a good exhaust shop.

[Trev88]

Custom exhausts sounds good and will in theory give u exactly what you want. Issue is workmanship. I've gone from custom to just putting on an eisenmann one. TBH I think the custom one sounds better but performance wise I think there is less restriction with the eisenmann when I drive. That's my experience. Another consideration is when u go custom u can do your mid pipes.

That said, custom gives u more bang for your buck. But good aftermarket exhaust are designed for the car already so they tend to be good too.

Hmmmm do like the bang for your buck statement.
