I don't want to mess with the CEL and I don't want to spend another thousand to get a tune.
I just added the X pipe with my AA exhaust. I also felt that the AA exhaust needed to be slightly more louder.
Man am I happy. The sound is perfect. The xpipe accentuates the high pitch sound coming from the AA exhaust.
In addition, I did not have to get the HFC's -which cost quite a lot.
I might be missing on the major power gains but the sound is well worth this mod.
