Yeah Clashez, I don't mind having to improvize a little or what I call modding a mod to make it function flawlessly.....sometimes it's necessary when dealing with aftermarket performance parts.....

So did you notice decent gains from the custommax headers? I have 180K on my car with stock cats, I feel like anything that gets rid of mine will free up a lot of lost horses.

You will definitely feel a difference, I know I did going from stock to eBay/custom maxima headers.. it well worth the money to get rid of failing pre cats and gain some power..

How many bungs do you need????? When you go to headers you'll only need the primaries which are on the headers already! The other two aren't really needed,.....you can use an O2 Sim!

Oh ok I get you, I wasnt sure if you needed to keep the other two or not to use an o2 sim. But when you put in for 2002-2003 it says "Note: We have not personally test fitted this year range yet. Can not gaurantee fitment. Requires adding an oxygen sensor on inlet on the front manifold" Last line says you need to add.

If they can't make a product fit correctly, what makes you think they know anything about the car

I had these a long time ago (but that batch fit except it required a hanger to be added). It's the same as any other headers. Sim the O2s and be done with it like Cmax said.
