I have a 435i M Sport and I currently have a VRSF down pipe (catless), VRSF Front Mount Intercooler, Burger Motorsports Cold Air Intake and VRSF Charge Pipe. Is it okay to run 91 Stage 2 AGG? They mention to have a full exhaust system which I don't have but is it necessary to have a full exhaust system? Or should i just run the regular stage 2?

“AGG” just means aggressive burbles. As far as I know, it offers no difference performance wise.

That said, I ran AGG before I finished my exhaust and it was fine.

AGG is a much more aggressive burble, you can certainly run AGG as long as you're rocking that catless downpipe as the unspent fuel and carbon deposits would damage a catted DP fairly quickly due to the delayed ignition timing. Most people running AGG with a straight pipe or high flow exhaust spit massive flames so if you're into that I'd highly recommend it.

I have a G20 330i with upgraded charge pipes, high flow dp, and AWE catback exhaust but it’s asking for a full exhaust. Can I run AGG?
