scott y Posted October 4, 2010 Report Share Posted October 4, 2010 The wife's 2002 STS has the rectangular exhaust tips(factory) and a buddy just recently picked up an '02 STS and his is equipped with the ol' elliptical tips. The exhaust appears to be original on his and I know that our's is, wonder why they could be different?? Link to comment Share on other sites More sharing options...
BodybyFisher Posted October 4, 2010 Report Share Posted October 4, 2010 Post a photo, Id like to see yours, I thought all were elliptical You have had your STS since it was new? Was your car modified when new?, freer flowing mufflers?
