I'm planning on installing longtubes pretty soon and I was wondering what parts need to be taken out. Meaning what I'll probably not be using after the install. Not what I need to take off for installing the headers. I know that it won't pass emissions anymore because I dont think that I'll use cats. I was just wondering what I'll be getting rid of. For the best results possible.

 

Ditch the EGR and AIR pump. And CHANGE YOUR MOTOR MOUNTS. Trust me on the motor mounts part, mine are rattling like crazy idling in gear. I'm going to put some poly ones in this weekend, I just can't take it anymore.

 

I already have o2 sims, but I was wondering if my car will throw a code if i do what speed_demon24 says to do.

 

You will need O2 extenders too...i would take out the AIR EGR and that's really about all you can remove!

 

Sorry, I forgot to mention that. I knew about the o2 extensions. I was just wondering if it would throw codes if I got rid of the EGR and theAIR pump.

 

You'll throw codes if you dont have them programed out of you pcm, but with headers you should get a tune anyway, you'll be running rich without one.
