Secondary downpipes, no.

Hi Vic, I ordered the Remus catback system and they are backlogged with orders. I was wondering about the downpipe issue thus I raised the question. It would be nice to get a slightly louder roar and tone, but again, I don't want it to be a nuisance and a pain in the ass in the morning when it starts up. I also definitely don't want a tune if a CEL is triggered thus asking the difference in the 2 sections of downpipes

The secondary/lower downpipe will not throw a code, I should have a few clips of Remus with the secondary cat delete pretty soon.

Just waiting on a few more parts for this build before everything goes on

How much power the car will gain from secondary keller downpipe? If I order the oxygen sensors bypass for the upper downpipe would the CEL be activated?

Secondary delete, I would say at the very least 10whp.
I don't have exact data.

For primary, for where you are at, a simple O2 bung extension should work.

Thanks, has anyone tried to use fabspeed oxygen sensors spacers with primary DP? Did you face CEL issue?

AFAIK, it is hit and miss.

Sorry didn't get you. Am I going to face issues with them?

Worked for some, and not for others. If you plan to tune you can remove the CEL that way as well.

Does anyone have a sound clip of just primary DPs installed with secondaries in place on otherwise stock competition exhaust? I’m kind of leaning towards this set up to eliminate exhaust smell. Had an F80 with full catless turboback exhaust and it smelled terrible, after driving for 1 hr even the clothes were stinking. 🤦*♂️
