Is there a big advantage in removing my cats all together ?

Will it get extremly louder ?

Or is this a silly delete to do ?

it will make it louder and you will have a weird smell from doing it. if you have a FULL exhaust (headers, mid race pipes, and muffler) along with add ons for the front half (intake) it will benefit you. I dont know if you guys have emissions regulations but down here we do so it gets more complicated

catless cars leave black soot on the bumper above the tailpipe

you may have experienced this, but I know many cars running catless and they don't have a black soot problem....I guess if the car runs rich and you get tons of black smoke that'll occur

i took off my cat. It's a bit louder, but I think it's pointless if you dont have an exhaust system.

MV325IS, dont do cat delete yet. Put that money towards something where you will feel any gains:
LSD
M3 Cams
LTW flywheel

I agree.... the cat back is designed to work with the cats. To take full advantage of such a mod, the entire exhaust system should be considered and designed properly.

The manufacturer may have more advice for you. It'll be a PITA for e tests too.
