Ok, I need some help spending my Christmas money. I would like to go with the long tube mac headers, but I have a few questions.
1)If I have longtubes installed, will I have to deletemy cats? (I want to keep them)
2) What happens to the existing O2 sensors in the headers, and what does this affect (CELs)?
3) About how much is the installation/fabrication for longtube headers from a muffler shop?

Thanks so much!

The install should be around $300 any more and you're getting ripped off. You will not be keeping your cats if you have longtubes unless you actually have a matching mid-pipe with highflow cats. As for the O2 sensors, they will be relocated and you may need to splice the wires or get an extension depending on what headers you go with etc.

Could my exhaust shop possibly move the stock cats further back?

You can get long tube headers with Hi- flo cats installed!

I just got the MAC longtubes and they are a very nice piece. You should also get the mac prochamber with high flow cats to go with the longtubes.

I got SLP LT's and a matching x pipe with cats. It comes with the extension cables for the O2 sensors. The ONLY down side is if you have lowered your car, you lose another inch to your ground clearance.
