Experiences with header/exhaust bolts for install
I am planning on ordering an RPI GTS system soon and was wondering what peoples experiences have been with the header/exhaust bolts? I am trying to decide on installing myself or having a shop do the work. From my understanding all that is needed is to remove the 4 bolts holding the current exhaust to the header/cats. Rest is just hangers/brackets.
I noticed the exhaust bolts are about $5 each, to me that says they are not special bolts. On my Z3 they were $25 inconel bolts. I was surprised ours are just ordinary. But that then makes me concerned about breaking one.
My M5 is a 2008 that has been driven in winter. Thoughts on if the bolts will come off easily or possible break?
I will of course be ordering new bolts for installing the GTS system, unless it comes with new bolts.
I have done 2 exhausts in the past. My worry is that if something goes wrong I cant drive the car and with the Z3 in hibernation for winter, that leaves me in a bind.
