By far the best exhaust I've heard for the e89 Z4...

[Bmurata90]

This is a full titanium exhaust system for the Z4 for $3200... It took me a little bit of time to try and find it because the YouTube video is from 2010, but I've located it and just wow.. A full titanium exhaust system for only $3200 that sounds like this?! Yeah, I think I'll take this.. Absolutely amazing if you ask me. What do you guys think about the sound? I'm curious. I'm also not a huge fan of fake quad exhaust so this is perfect for me.

This is the website and link to the part. Just use google translate and send an email for inquiry if you're interested! Sent mine in today and will let you know how much the cost of shipping will be.

Not sure, but you shave off 39 lbs/17.6 kgs of weight compared to the stock exhaust system. But yes, it's full titanium.

But what does it sound like in stop and go traffic ? Even straight pipe sounds ok at WOT, cruising in traffic is a whole different story.

You can hear it when he's not in WOT. It's pretty quiet.

Yes, but that is not the same as stop and go traffic. Once again, a straight piped N54 at WOT on a wide open track can sound amazing to some. How ever, accelerate from a dead stop in traffic or a light, and it will sound like shit. Do this in traffic for 2 hrs and it gets old FAST.
I am not necessarily speaking about volume/db, but the actual tone produced.
I am not knocking the exhaust posted just asking a simple question of what it would sound like on the street in traffic.
