can anybody tell me what are the pros and cons of these headers? will they work with stock plug wires? can i use the factory y pipe? what if any issues will i have during installing?

 

I'm not sure about the y-pipe, it should say on their webpage though. Yes you can run the stock wires but you'll want to be careful routing them and ensure they are not going to hit the headers, as they will burn. Also, typically people replace the plugs/wires while doing headers because they're due for a tune up, and it's a lot easier to change the plugs while the headers are out. Shortys aren't too bad as far as installation goes, but definitely have a buddy handy and plan on a good full day if it's your first time.
