Catless Downpipe for N52 X3?

x3mart33 · 02-22-2022, 05:36 PM

Looking to improve the sound (mainly) as well as airflow in my x3 but i cant seem to find many options out there. Any suggestions? My state is against cutting off mufflers and since its a daily I really don't want to do that.

Car is 2011 28i.

Your state is against removing the muffler but are ok with you removing the cat

Down pipes can be switched out, i don't want to have to weld a muffler back on just for inspections.... Appreciate the insight LMAO

So you'll swap to the stock catted down pipe for inspections, then swap back to the catless down pipe after the inspection, got it... LMAO
