DownPipes Question

007_e350 · 07-15-2013, 11:35 AM

Looked at BMS and VSRF a couple others but none have the shock dampers built in like the stock ones do .. why ??? Does anyone know if one aftermarket that have ?

because is not needed and expensive to built. if you want that get the superprint one.

.. a flex section ? Akra and Supersprint downpipes have this.

I believe the Wager DP's have a flex section too.

Not trying to be a smart-s. But if it's not needed why did BMW build them with those flex sections stock?

For better thermal expansion, since the OEM downpipes have massive cats that retain alot of heat. Aftermarket downpipes with flex sections are going to be preferable, but cost more. To cut costs for both the customer/manufacture, most leave it out because it isn't "needed" per se.
