dAHLer Performance Cat-Back Exhaust System BMW M3 Competition Sedan G80



Please note that the design of this exhaust has been updated to no longer have the center brace on the piping that resembles an H. Originally, this was just a brace to help hold the piping together but it is an easier install without this brace in the middle so that has been removed from future exhausts.

  • We are typically very quick and have a 24-48 hour turnaround time (this applies to products we have readily available at the warehouse and not a product that requires special order). Transit time depends on your order and which warehouse we are shipping from, but typical transit times are between 5-7 business days from one side of the US to the other. Larger items like bumpers and body kit conversions can take up to 10 business days to get you from time of ship.

    Majority of the items we offer do ship free to the lower contiguous 48 states. States that require plane or boat to reach (such as Hawaii, Alaska, Puerto Rico, etc) do NOT qualify for free shipping. Larger items such as bumpers, hoods, fenders, also do NOT qualify for free shipping. Please contact us to inquire about international shipping costs. During checkout, you will know which items ship free and which have shipping costs associated with them. In general, larger/heavier items will have additional shipping costs (body kits, wheels/rims, etc)

    Even though everything can be shipped internationally, sometimes the cost is simply just too high and doesn't make sense to do so. We're here to make sure you have a great shopping experience, so if you have a product(s) you want to inquire about, please contact us at
