I recently picked up an SLP X-pipe with cats and the offroad add-ons so I can take them out. I also got the Steeda catback. I haven't put them on the car yet, but I'm looking to do that this weekend. I have been told that without the cats there would be not enough backpressure? I figured maybe I should upgrade the MAF and add a CAI with it. I was looking at the WMS systems and they sound good, but I'm not sure if I should go with the 87mm or 95mm. The car is bone stock right now except for the exhaust that I will be adding. I am planning on supercharging the car in the future. I don't want to push too many PSI since its my daily driver. Anyway, should I put the cats on now before I get the MAF and CAI, or does it not matter. Also, is the 95mm too big for the car now? I don't see it being a problem with the S/C when I get it.
 
I don't think you need to worry about a MAF at all. As for the CAI, the K&N FIPK seems to be what most people get, but you can do fine with just the filter. I have a JLT True CAI and it showed great gains on the dyno, but the fitment is very poor and its a bitch to install.
 
If you plan to s/c, then you will not want to use the 87 or 95mm MAF that come with that CAI kit. Just an FYI.

You will be fine with no cats. A majority of people here don't have cats.
If you plan to s/c, then save your money on all the bolt-on engine stuff and just wait for the blower....otherwise you will end up having to sell it all because it won't work with the blower setup.
 
Had an O/R x-pipe with Borla cat back on the '01; pretty loud even with the Borla. Took the x off and put the stock cats back on to get through emissions. Seems to feel a little "bottled up" and is quieter. Haven't put the x back on yet. Meanwhile, had it dynoed without the x; 300.2 RWHP; 299.4 RWTQ with a MAC CAI as the only other change.
