Was going to post a clip up a long time ago, but had problems uploading it. This is my 540i wiith stock cats, resonator, but no muffler. I'm happy with it.:)

Oh, it cost about 40 bucks for all the pipe, pipe clamps, and muffler tips. Took me about 3 hours total.

daaaamn. kickass sound, very nice tone. regarding the pipe, you made a custom setup from where to the end or just deleting the muffler?

Thanks man. I just cut off the stock muffler, and ran a pipe out the back.

That is kick... ass.

not bad, does it stink?

that sounds sweeet.

If you stand around it for a couple minutes, then it does just a little.

Thanks. It's kind of weird hearing that out of a bmw. best 40 bucks I've spent on the car.
