Mine has 2. 1 at the Y and the other after the cats.... But I seen other say they have 4.....

that is four.

any obd2 setup will have four total.

Mine had 4. 2 uppers and 2 lowers. When I had my hoe tuned I got my lowers turned off. At 50 a piece and deleting my lowers I save 100 bucks and if I need to I can all ways turn them back on

That was exactly what I wanted to know if it would still worked with just two upper o2 senors

it can but the rear two just dont monitor the cats they help tweak the fuel trims slightly to make sure the the cats operate correctly and therefore have a better mixture to run off. so they do help a bit the cats that are installed. and state laws are not. removing or gutting your cats are are a federal crime. whether someone looks for them are not.

Going thru same dilema. magnaflow tells me there 23453 wont fit a 2 door,only a 4 door. flowmaster says there #2010023 cats will fit a 2 door. I measured length. sure looks like magnaflow will work. Possibly going to go with flowmasters force 2 cat back system and 1 or the other cat s.

Really? They said won't fit 2 doors?

I just installed Magnaflow 45453, California version of direct fit cats on my 2 door, I believe 23453 uses same tubing as 45453 looking at pics and dims. Perhaps they were thinking of the cat-back system?

Straight forward job swapping it out, major PITA is unbolting the stock pipes off the manifods. This is after soaking the crap out of hardware 3 nights in a row with PB blaster.

Little late but hope this helps somebody.....

it is suppose to fit 2 or 4 doors the 25453 in the non cali legal version. 45453 has a different more intense chemical build

Does anyone know if this magnaflow cat set up for 4dr will fit on a 2 door?

yes. the difference in the two vehicle exhaust system is in the muffler section.
