I snapped the exhaust reversing out a steep driveway, i caught the tailpipe on the road and it snap completely at the weld where it joins to the muffer box under the back passanger seat. As for stalling it hasn't konked out on me yet but it shutterers heaps like it's going to and it seens to be a little underpoweredand 3 --4 seconds before it starts. Also i've noticed when i'm driving and i take m foot of the accelerater it seems to putter/misfire (without the bang) sorry if this confusses you lol i'm not used to explaining car stuff to people cus i don't trust anyone i know to help me
