I doubt if there is much benefit to exhaust mods unless you increase the intake flow substantially, and I'm not sure different filter cause enough air flow increase to be felt. Different filter can filter better, but for increased air flow to a significant degree, I'm not sold on this yet.
I 'increased' the intake opening area @200% over the stock opening, so maybe the 2" tip is doing something. I know the fire from the backfire is longer and the sound is a deeper growl which I like, but I'm not sure there is more forward bite from the tip.
Well I can say I did notice a difference, and the exhaust popping I got tells me I did increase the flow.
