I don't think so. But if someone does see a problem with it, please let me know. After getting a ticket, I had to take my Hotshot header out of my 1.6 and I put in my stock exhaust manifold. Being lazy, I didn't put the heat shield back on. I've been running the car like that for about 3 weeks now.
hey , check this out,
After my first failed header attempt,
I put the original manifold back on and was too lazy to put the heat shield back on. A week later I get a radiator leak up top across from the manifold. I dont know if it had anything to do with it but I would definitely put it back on. Besides, would you want all that heat everywhere?
