I'm getting ready to put on a set of Pacesetter LT headers with a Y pipe. I didn't know if the dynojet oxygen sensor eliminator actually works or do I need to weld on a new bung for the rear sensors?

 

I would weld on a new bung, and call it a day.

 

I went out and bought 2 new bungs today. I also ordered walkers O2 sensor pipe but don't know if it will fit because they don't specify dimensions and I can return it if the diamater isn't what I need. I will more in likely end up drilling holes in the Y pipe and welding the bung on for the O2 sensor.

What are your thoughts on doing a cat delete? Or a high flow Cat?

 

Depends on where you are. If you have emissions testing/inspections, then you MUST have a cat. Also, it is federally mandated..... so, not having one is technically illegal..... High flow cat would solve both issues.

 

i have to get inspections every year but the guy I always take it too never checks to see if it has cats or not. When it ask him in the computer he just clicks yes without looking and proceeds

 

So long as you can still go to him, you can do pretty much what you want, but, if he moves on to some other job, you're screwed....... Up to you.

 

mid he moves or gets shut down I can just weld some cats on there and call it a day lol I have a welding machine at my house and 2 cats but from all the research I have done it seems like without cats gets better gains than with hogh flow

 

Unless your cats are REALLY crappy, (very restrictive) they really don't make all that much difference.
