Removed the stock exhaust shown and replaced it with the parts seen last night. Dynomax super turbo.
Sharing sound clips from the install further below. Was looking to get that performance gain and not be any louder than I need be. After looking at muffler difference and how to get quiet performance.. video reference below from David Vizard. If you remember the Cyclone Header company this might have more weight in you consideration. It’s only 20 mins nd you could skip over the first 3-4 minutes intro.
Went with the Dynomax part number 17749 with the full offset to take best advantage of the original flow director design. If you keeping the cat on - recommend you stay with the center inlet part number. What I like is that it does not neck down internally and runs two 180 degree turns to maximize its time in the muffler.
I based line some 3rd gear pulls from 2000 RPM to 4500 RPMs pre modification. Averaged out they were 11.43 seconds
Stock sound clip taken at 8’
I will come back with updated timing when my co-pilot is available but I my attempt to self time I was in the 10’s. So it’s got a little more pep.
Updated: 10.8 is the new average..that’s 5.5% improvement. I will take that and the wife commented there is no difference in sound going down the road, another win. Looking forward to seeing if the MPG follows with some improvement.
Dynomax sound clip again at 8’
Over all the sound once warmed up is very good, going down the road at cruise. A little louder of course under full load but nothing that brings attention. Cold start idle is most notable with deeper and louder tone. Tempted to go full implementation and add a resonator, just to see what it does/ or not do.
