I have an 04 so I have 4 cats. Am I able to simply get two of them cutoff and not have to worry about any problems? Would it be better to get 2 cut off, or get all 4 replaced with a magnaflow highflow cat?


If cutting two would work, but would throw a code, could it be fixed by a custom tune? I have a custom tune and the guy could alter it for me.

 

Replace all four with 2 High flows! No codes if O2's are re-positioned properly, and yes you could get rid of the CEL the tuner.

 

Replace all four with 2 high flows. If you get a code, just do the Gotts mod!
