Are powder coated headers better than polished? I plan on getting some LT's and ORYbut idk which kind to get. Cost not concerned, which ones give the most increase in power? How can I tune my car to thinking it has cats or where can I get 02 simulators?

 

Powder Coated headers don't perform any different than polished. The inside of the headers are the same just the outside of them are different to give a different look or protect from rusting. As far as the 02 Sims go I would have to say try Froogle.com its google shopping so if they exist (which they do) you will find them.

 

you can make them pretty easy. But I have some fore sale.

 

How do you make them?

 

If you dont want to buy 02 sims you dont have to it will just throw the check engine code for that, or you could have someone delete that code for you, using ls1edit, hptuners or any other tuning software
