I once (recently) posted five videos of me running my car with HPTuners connected, doing various things like tapping on the top corner of the cylinder head, denting the **** out of the Y pipe with an air hammer right where it hits the floor, and two hard runs shifting through 2nd and 3rd with the Y beating the **** out of the floor, also one low rpm high load test to show KR on the screen. Both the screen and my tests were in view at the same time and nothing caused KR (except for the low rpm high load test, which was 5th gear and increased throttle enough to get one degree)
So....I don't think the Y banging causes KR, and a fuel line sure as hell isn't going to cause it.

Verdad Gallardo I had them on youtube, took them down.
What I figure is if you're making enough power to twist the engine up to where the exhaust bangs the floor, the KR is more likely coming from being under high engine load. Or it's torque management pulling it. 15* is a lot for a pipe banging. Pretty much a common number when TM kicks in.

Well it's going to take a while to put the stuff back on youtube.
(upload time)
anything specific that would convince someone banging stuff doesn't cause KR?
I'll put that vid up first or make one.
If someone has an idea and wants me to make a video I'll do it. I originally wanted to put one camera under the car to show the pipe hitting (out of my curiosity)
I have five videos, I might be able to do something Monday, going out of town for a week tuesday.
I'll prove a banging Y pipe isn't causing anyones KR.
