Arrow E90/E92 M3 Exhaust Systems Overview

I thought it would be helpful to have a reference thread. This thread was created as a primer, not a one-stop thread, and the burden is still on the buyer to do his/her research. I'll try to keep the first post of this updated... the thread will definitely be a work in progress.

Note: Prices may be off. Some prices are introductory prices, some are estimated prices before production, some are MSRP... I have zero interest in keeping track of prices as they fluctuate (across time and across vendors).

- Please refrain from starting up discussions about specific exhausts.
- Links to the manufacturer/performance line are in blue.
- Links to the primary distributor are in green.

I'd like to keep this as useful as possible. Suggestions, corrections, comments are all helpful.


*Please check out frankzlin79's thread for an outstanding video comparing multiple exhausts:
