I have read many previous threads on how superior the performance is. With the upgrades we have made in our 2 DBs, and resulting increase in power and speed, for safety's sake its time to take the plunge and upgrade. My questions to those of you who have installed them:
1. Are they really and truly a SIMPLE "bolt-on" replacement (as claimed), w/o any modifications needed?
2. How are they holding up with time/use- any problems?
3. Which parts supplier are most of you purchasing from?
Thanks for your input.
