I currently am running BBK Equal Length Shorty Headers. I was just wondering if its worth it to switch to full lengths? would I get any noticable increases or is it a waste of time at this point?
I think, as you said, at this point, it is a waste of money and time.
I just did the very same thing you did, switching from equal lengths to longtubes. I noticed nothing significant enough to really warrant buying them. On a 302/306, the only reason I would get them is for sound (I like the sound better) or if you want every little bitty bit off of your time...
