Is the rusted heat shield necessary? I wanted to check/ clean my turbo, but I broke one of the mounting bolts clean off. the other two seem to be just as frozen. I've tried penetrating oil for about a week now and get nothing. Can I just remove it and forget about it, or does the heat actually build up that much?

 

Thats actually a good question... im not sure about that, but ive seen people taking that out and heat wrapping their exhausts... which looks good imo

 

I like the look of the wrapped manifold, but I'll wait until I upgrade my turbo to an Evo III. I've heard that some have issues with the heat affecting their hood.

 

mmhh well thats if you have a bare hood, thats why the stock comes with a black cardboard paper thingy.... and aftermarkets have this silver thing similar to the audio material to keep the sound in the car
