Default Borla XR1's

I am considering going top true duals in the near future and want to do it right the first time. I am hopefully going to do true duals, with X-pipe, into XR1's, then over the axle and out the back (if there is room, car is lowered). Curious about the different kinds of XR1's that are listed for sale.
They have the Sportsman, Circle track, and the shootout.
I assume the sportsman is what I would be looking for as I want it as quiet and as tuned sounding as I can get it.
Now, for the sportsman series, they have 12", 15" and 16" versions. What will the difference in flow and sound be between these ? And why is the 15" $179, the 12" $139 and the 16" $145 ? I would think the longer the more expensive ?

Can anyone help me out here ?
Thanks!

price is dictated on demand/what the market will pay. apparently the 12" is not in high demand, or they have a surplus. just a thought. also might want to measure the LM resonator. would help on what length you need i do believe the sportsman is the one you are looking for, but double check that.

The longer the muffler the quieter it is.

I sold my XR1's to O1Z so you'd have to ask him what size they are, but I think they are the 12" Sportsmans.

PSJ, since you had them, would you say they are about the quietest muffler I can get that will fit in there ? I was actually thinking of true duals with X-pipe, then into dual bullets, then over the axle into dual XR1's.

x,
into bullets,
into xr1's,
with stock cam,
means it will be as quiet as stock at idle.

I just ordered a 14" XR1 for my car, I'll tell you how it sounds when I get it on. Right now I'm running QTP headers into off road pipes and an SLP Loud Mouth, and this thing is "arrest me" loud!
