There was a link here on how to remove the CAT, but it appears to be gone.
Anyways, i heard you do not need a TFI. if you remove the cat, but in my opinion you are going to, because you are losing back pressure.
I went with a set of 09 headpipes and kept my stock, just in case
My dealer is removing the cats i think for $ 50. but then they ar epushing you to get their Racetuner, dyno.
I added the Gen3, samething as the TFI....best choice for me
Dbmg, Thankyou for the info. I wasnt to worried about the EPA, iI`m in Canada and don`t think that it is as much a worry here as in the US. And i have been looking for a 09 header pipe but a hard thing to come by.
The link that was here had pics, showing, cutting in half, and using a air chisel to clean it out. Also, mark a stright line on the CAT before you cut, that way you can line it up before welding it back together :s
