Currently, I have BPM GT TBE, which in my opinion is one of the loudest in the market. I am planning to sell it locally and get Borla Hush catback system. What DP would work the best with the system?

Thanks in advance!

When people order catback system and downpipe separately, what do they do to complete the midpipe section? use stock?

There have been several threads on here recently but I still don't remember the details. I do remember that the Cobb DP fits up correctly, and I have ordered it to go with my new Borla Hush.

The PDE downpipe would work as well since it uses the stock donut gasket. It also fits perfectly and has a mechanical CEL fix so you don't have to splice into your O2 sensr wires.

what would you recommend for midpipe?

The midpipe is part of certain downpipes, like PDE, Perrin, Helix, Cobb, and Invidia. Others don't include a midpipe section, like Bosal and Stromung. I have a Bosal with a Daddy's 3rd Cat Eliminator (mid)pipe, which mates up to my Hush perfectly.

I switched to a Hush from a HKS. I kept the HKS down pipe. The coupling is different, though if you get a donut gasket, it'll seal correctly.
