BM3 Stage 2 DP

Hello,
I am debating going stage 2 with bootmod3 but in order to do this they recommend a downpipe. I am moving to California soon so I do not want to go catless. Would a hi-flow catted Downpipe be ok for stage 2 and is it worth the upgrade over the oem? Also does anyone know if I can adjust the burbles with the hi-flow catted downpipe or will it damage it like the OEM one?

I run a fabspeed catted downpipe with no issues. The burbles work just fine so far.

You should be able to adjust for some mild burbles and good quality hi flo catted downpipes will definitely do the trick. ER catted are great as well as Wagner.

Stage 2 is fine with catless or high flow catted

I would run mild burble and not aggressive with catted downpipes
