I've replaced the exhaust on my Vintage Speedster with an exhaust that I beleive is referred to as a "Tri Mill", it is more realalistic looking, and I love the sound and looks. However,there is no space between the pipes and the valance below the bumper. I have been un-able to gain any space at all. I do not want to notch or cut the valance. Will the heat from the pipes create a fire hazard or in any way damage the fiberglass?

As a minimum, put a thin sheet of aluminum between the header/ collector pipe and the fiberglass. Even with minimal clearance (more is obviously better) this can drop temperatures significantly. My rear valance fiberglass was so hot I could not hold my hand onto it. I added an aluminum heat shield and now I can hold my hand onto the fiberglass anytime.
I just modified a VS trimill last night (getting ready to post a thread). If the regular tri-mill is built the same way as Kirks unit, I cant see anyway that the tips could be bent. The tail pipes go inside the can a good inch, and both the steel and the welds are very very hearty. Took me quite a while to cut them off. As well, there is a normal trimill hanging on the wall at a local VW shop. When comparing the two, the tips on Kirks are significantly lower - maybe as much as an inch.
