Im new here my name is Chris and I own a 2007 Pontiac Montana SV6 named Bessie. I got her back in 2017 from my grandpa at the age of 17. She is the first and best vehicle I've had so far and can't say much about my cruze which was originally supposed to replace it but couldnt for how many times it breaks down. So I kept Bessie and she is one strong van. She has a 3900 lz9 v6 under the hood with a k&n drop in filter and the engine is mounted to my just rebuilt 4t65e transmission that I added some things which was a zzp 4t65e transmission pan and a zzp 4t65e transmission shift kit. For her exhaust she currently has stock cat but a new slightly louder than stock muffler that I can't stand and stock resonator and no exhaust tip. I will be re doing my exhaust soon. The setup will be cat to a resonator after the 02 sensor  to an exhaust cutout to the muffler and hopefully a new exhaust tip. I also have done exterior work. Ive painted the chrome grills black, bought black headlight housings off amazon, a small stuby radio antenna from amazon, and put fast hd thunder wheels on FIRESTONE FR710 road tires that are the stock size 225/60R17. The rim itself is 17X8 and is a 6x115 bolt pattern and was the only option I could find while looking for wheels for the past 4 and a half years of owning it so far. My other plans are eventually doing a 3800 supercharged swap with her and building the motor but for now the 3900 v6 is good. Cant wait to hear all the good advice and thank you for welcoming me into this amazing community.
