Failed engine mount bolts - modification Q\'s
Two days ago I hit a bump in the road and my engine dropped a few inches on the right (passenger) side, crushing the exhaust manifold (which is how I realized something was wrong). It appears that when I had the timing belt replaced 20,000 miles ago, the mechanic didn't use any compound on the threads, and one of the bolts worked free, overloading the remaing bolt, which broke. My questions are these:
1) Is there a recommended aftermarket exhaust manifold that would increase performance?
2) Is there an aftermarket skidplate anyone would recommend, so I don't have to replace the broken one with another plastic piece of ****.
3) A friend recommended replacing my mounts with aftermarket mounts, or mounts from a GTI. Any thoughts on the benefits I might derive from this?
Thanks in advance for any help/thoughts.
