| Corsa Exhaust
I had installed my Corsa axelback on my 2005 STS in April of 2009...recently I had gotten under the car to adjust the alignment of the pipes for the 2nd time...it seems the right muffler eventually tends to stick out a littler more than the left even after I had aligned them...this happens about a month after I adjust them (after settling in). I also notice the difference more after my commute to and from work...could this be perhaps to thermal expansion...??? not sure...but it's kinda annoying...just wondering if anybody has any idea to why the mufflers won't stay exactly as i adjust them...the change is maybe a half an inch at most...but I am a perfectionist!!! |
