Long story short, when I had my Jeep straight piped...it turns out the guy that did it chopped the muffler along with the flanges. My Borla S came in today. I was excited as **** to get it on. Got the vehicle lifted up to find there were no flanges. The shop that did the initial work doesn't sound like they want anything to do with it now (said booked out for 2 weeks). I'm not even sure how they would go about making it work. What's my next best option? Hi flow cats? Or find some stock cats somewhere? Or what is the actual name of the part that the Borla S attaches to? Any input is appreciated. Thanks!
