Are you out of warranty? If you weren't before, you probably are now.
Interesting choice of things to modify.
Assume it sounds good? If that was the impetus. Or has the horsepower/torque improved?

Inquiring minds want to know, how did you get to the point where you said, I am pulling off this NPP setup and will try to make it better. And how did you know that going from 2-14" to 2-3/4" was the sweet spot for flow ?? Was there an assumption that by opening up the diameter to 2-3/4" you would get better flow, performance, sound ?? Curious to know the specific reasoning here. I guess cheaper than going aftermarket, but the engineering side of me is curious to how you got to this point and the decisions made along the way. Thanks !!
