ok so me and my girl friend are leaving my house. she gets in her car witch is parked in front of my house and I get in my car witch is parked in the drive way. ok so the road travels north and my drive way travels east. ok the meet at a 90 degree angle. im backing up, just rolling in neutral down my drive way. I look down the road south and she just my girl friends car then I look north up the road for cars. all of this while im rolling at about 4 mph. I live on a privet road with like 20 houses no there is never any traffic. as im looking up the road my girl friend decides to drive like right behind me. about a second before I get to the end of the driveway. BAM I roll right in the her. I had no idea what she was thinking she said she thought I would stop and let her go. now im not saying it was all her fault but come on. any who I smashed her mirror and dented her door bad the only thing wrong with my car was the Exhaust it like cracked by the engine. so I took it to the shop and had to get a bracket welded back on and replace the joint thing. you know the mess looking thing in your exhaust. now the question I noticed after this my turbo is way loader and seem to boost a lot more. why is that. the shop said the mess thing had been **** any way.
