Bought used. Full disclosure driver's side looks to have been opened by previous owner but I ran them for 20k miles with no issue. No longer have 4Runner so don't need them.
That looks like a Dometic for sure. Mobicool also makes the MCF40 which still looks like a Dometic. Sorry OP, I don't have experience with Aplicool. They are all over Amazon though and Amazon has a pretty good return policy if it doesn't work out
The procharger seems to be looking good if you want both better power and better MPG. One member here reported low 20s for MPG and noticeably more power
How short did you trim it? Thinking of doing this on mine because new rocker trim doesn't seem worth it to me. What's the measurement from the bottom of the driver's door to the bottom of the cut? I guess that would be the easiest way to measure?
Forgive my ignorance but how is this different than just chopping the exhaust shorter? Maybe I don't have as discerning ears as some of you, but the stock exhaust doesn't drone or sound bad to me.
