I personally already ordered a cattled downpipe, I guess it's too late to change. However I am open to hear any concerns.

My understanding is it used to be removing cats would help performance. Removing modern cats doesn’t help anymore, other than additional pollution with the benefit of sounding a little cooler. |
Yeah. There are better ways to make power now and cat designs are good enough that the difference in peak power isn't enough to warrant the extra emissions. The other reason we used to run test pipes was spool because we had fairly low static cr, which is why "turbo lag" was such a big deal. Modern direct injected setups run much higher static cr and have plenty of off-boost power
