thank you Sir!!!! i will order that ASAP lol

 

two mufflers, WOW

 

I think the front one is just a resonator. You could take that $80 and buy gas and cut off the stock muffler and run a pipe with downturn out the passenger side rear. Leave enough so you can replace the stock muff or replace it with a different one if you do not like the result.
About $20 for a shop to cut, shape and install a piece.
Other option, remove both and put an inline muff where the resonator was but I don't think it would sound much different. That would still get that monster off the rear end and give a throaty sound. Either way you would then have the option for an onboard air tank back there.
Save money and weight. I first did this on an 06 I-5.
