If you installed it yourself, or have looked under your car and have seen where the midpipe connects to the stock downpipe. Were you able to reuse the stock bolts or use the ones that were included in the kit? I could not get either to work(to short with the stock ones, and wrong thread with the ones in the kit) and ended up having to use the bolts from the stock axleback section without the springs on there, to bolt that section up and it seems to work but worries me that it should have those springs on there. Any information would be greatly appreciated. This is for a 2012 tc btw

 

I don't have the spring bolts on mine and it has been fine for about 10,000 miles or more. I will however put them on sometime because it is an extra flex point. Doesn't really affect anything as long as your not off roading you tc lol
