Ah, you remember- yes I almost went with the RR II, but a couple things changed my mind.
Eventually (maybe this winter), I want to get some engine work done- there is a guy that does something with the stock cams, ports the heads and throttle body, and apparently gets great results (he says he gets 105 hp/130 tq out of the 110's). Thing is, for the combination of the work he does, he says it's best to leave it as a 2-1-2, and he likes my Fullsac headpipe (or even a gutted stock header), because that is what he knows works with the other stuff he does.
Also, if I did go with the 2-1, I'd probably miss the cooling factor of the ceramic coated header I have now- if I wanted to have the 2-1 header ceramic coated, there's another $100-$200, on top of the $1,000 for the RR II and Psuedo pipe. Plus, this drastic of an exhaust change would certainly require a new map and V Tune, wheras the Rineharts shouldn't affect my present map at all.
Also, I have been given positive opinions on how the RR II would perform on a stock 110", but in a way, it's no guarantee- the larger 2" primary tubes might be too much for a stock 110", and I may have had tuning issues.
So, as you can tell, I put a lot of thought into it, and hopefully I'll be satisfied with the Rineys.

I figure with the money I'm saving with just buying slip ons, I will put towards the engine work in the future.
