Hey guys. I'm looking at installing headers on my LG4 engine. It still has the stock manifold on there. I looked at the bolts and they're pretty rusted. What are the chances of one of them snapping and how screwed would I be? Thanks

 

I'll say at least two will break where they mate to the exhaust pipe and maybe 1 or 2 on the engine block lol. but if you spray the s*** out of them with WD -40, let it sit, spray again, let it sit, and spray again you should be able to get em all off okay.

 

Haha alright man. In the situation that they would break, how hard is it to get them out again? Thanks again

 

Run the engine untell it is heated up good and dont burn urself
then spay the bolts with penitrating oil then try to get them out

 

Alright thanks guys. I'll give it a go once I get the money and let you all know how it goes. How much do you think I could get good headers plus a Y-Pipe for my engine? I think I'll just remove the cat, and I already have a flowmaster in place with a single inlet. Thanks

 

Get something like " Nut Kracker" if you can find it specific for loosening, and dont cheap out on the 175$ flowtech headers, I had to get a custom 3" y pipe made for 500$, and the headers are having issues with gaskets, just get the Hooker deal with headers and Y pipe for 500$ save a world of grief, and get those silver heat shield boots for spark plug wires.
