Hours?
David,
How many hours did you get on the 1.5" system? Did yours have the mufflers installed?
What I was really wondering was, if any one had accumulated lots of hours on the system.
Although I am still trying to get my head around the concept that restricting airflow cross-sectional area by 25%, increases performance, the added performance noted on the dyno tests is really not as important to me as longevity and no long-term adverse affects on the engine.
Also, even if performance wasn't a factor, the smaller pipes and lighter weights (2lbs) are a positive in a crowded engine compartment.
If it is as good or better than the original Vetterman system it is a winner.
