The title says it all. I recently upgraded my stock rims and tires on my 17' 340i and went with some 19'' wheels with new tires. So my next project will have to wait until early next year most likely. I am looking at putting a performance exhaust system on my F30. I really like to way quad tipped exhaust looks on an F30 and I was wondering what the conversion entails. Has anyone done a quad exhaust on their F30? I'm just trying to get an idea of what something like this would cost. Right now I am leaning towards at cat back Remus quad exhaust. I've been looking online for an M sport quad tip diffuser . Is there anyone who can help me with this or give me some tips on what to do? I appreciate any help or insight!

You might catch some slack for this conversion, but it's definitely possible. A local 340i has an m3 exhaust and rear bumper and everyone gives him a hard time.
