Im just wondering what should be done next: x pipe or a tuner? I already have a cat back exhausr, t/b & plenum, and a cai. Thanks

you'll probably get better use out of the tuner but the pipe will make your car louder, so you decide.

If you elect to go with a catless midpipe you'll need the tuner to turn off the rear O2 sensors (make sure the one you buy can)--or you can make your own MIL eliminators for $5 or so.

The midpipe will open up some power, in the upper midrange and high revs, without a tune--but do the tuner next.

As to catted vs. o/r, about all an o/r road midpipe offers on a "bolt-on" engine is more noise and a stinky exhaust.

i have magna packs now and i was looking at catted pipes. Will it be louder that it is now? Because I don't want to go to much louder.

Of course it will be louder with a high flow catted pipe, but it will have a nice, clean, and deep sound that would be good IMO. If you don't want it any louder, then don't change your current setup....plain and simple.
