This is a DIY video of what the stock exhaust on my 2021 330i sounds vs the AWE track kit. It took about 2 hours but thats because I screwed up once finished and had to take off somethings and reassemble. I will leave a link as to where i purchased since they have it on discount at time of uploading video. I bought my exhaust pipe cutters from Harbor Freight, not worth it. Better ons on amazon I will leave the link below. Enjoy!
