The dreaded Y piece has been removed and the Magnaflow has been installed. If you are near Colorado Springs, The Muffler shop on 2115 E St Vrain does quality work. Here's a quick photo I took after it was done. https://photos.app.goo.gl/UHlRVNKP4s0QB2sQ2
I used my Google photos. Are they still not showing?
That's the same muffler we used on my daughter's Xterra so I was familiar with it. It's not too loud but you can hear it when you get on it. Definitely not a ricer sound. I will try and get some sounds clips tis weekend. There is a little drone but I haven't driven except home George muffler shop. I will try and see what rpm speed causes it.
They tend to sound better when you get somewhere around 500-1000 miles on them. I got the 12580 on my 06 Pathfinder with DT shorty headers and DT mid-pipes (eliminates the rear converters) and kept the stock tailpipe and post-muffler. I definitely notice a drone during light to mid-throttle acceleration, but idle it sounds good and at wide open throttle, she sounds great! That said, I didn't notice any real gain in gas mileage nor performance with just the exhaust mods. I later added the XTP plenum spacer, aFe Momentum intake system and reprogrammed with a Superchips tuner to the 93 Octane performance tune. The biggest "noticeable" increases in performance came with XTP plenum spacer and the Superchips tuner.
