I was more specifically speaking of the ghost girls & coffin ones.
What is scary about that?
A little girl and/or "dead" guy are obviously no threat unless you are a superstitious girl.
This is puzzling....
I've personally seen them toss a "Cooling System Performance Malfunction" CEL for when the cooling system fails to reach xxx temp in xx time or fails to reach xx within xx of operation ect. ect.
Who knows what happens on that generation, but it seems unlikely that the CTS could see -41 when logically your external temp, or even IAT is above 50 Fahrenheit. Should have tripped some logic.
FI makes some nice stuff, their big diameter down pipes are the shizzy IMO
You can't really go "wrong" with a catback on these cars though, as they all sound good.
Fav's are probably the AWE Non-Res as noted, and probably the milltek non-res.
B6/B7 S4's look great, sound great, just don't accelerate or take to modding so well.
PS: A lot of early 04's had tranny problems. Any idea on your build date?
First mod should def. be a catback.
