Fab speedF10 M5 downpipes ?

Anyone try these yet? I assume a cell even with the catted ones. It thought downpipes made more than 15 hp? Can't seem to find any with 400cell cats.

Are you planning on running a tune to increase boost with DP's or just wanting a bit more noise? Without running more boost you won't see much of an increase in power with DP's alone.

AMS has 300 cell catted DP's that i've heard great things about.

I bought a set of the Fabspeed catless downpipes and returned them for 2 reasons: 1) they are smaller diameter than OEM, 2) O2's are not in the factory location and hit the firewall when installed.

The AMS and Supersprint the O2's aren't in the stock position as well. I couldn't clip the rear O2's into the oem routing position, as the cables were not long enough, so I just laid them off the clips. I wonder why they couldn't make it in the same location as the stock DP's. It seems like it could be easily put in that location because the stock downpipes take up much more space than the aftermarket ones.

No tune. Just downpipes. Are there any catted pipes that won't throw a cel?

I have had buys run these O2 spacers with the built in catalytic converters, and they help out A LOT. I dont think i've seen anyone that ran these throw a CEL. J

You shouldn't have any issues with a CEL with the catted downpipes. We have had a high success rate with the Catted O2 Spacers for keeping the CEL off. Do you have any other questions?
