What was changed exactly? Stock manifolds?

[Jamescorbett]

Just put on stock muffler. thats it still has the headers .

[Jamescorbett]

Truck was to loud and had to hear the neighbors cry.

[SiriusC1024]

Check out black widow exhaust. Best sounding I've heard on a truck, and they're cheap. Quiet idle, but they sure get loud when you want them to. They even have a 'Neighborhater' model lol.

I had to change the exhaust and go back with stock style and the numbers were crazy on this run i hope that doesnt mess it up .

Numbers aren't crazy at all. Still have the slow O2 problem. Maybe throw a set of Denso O2's in there like you're saying.

Here's for now.

Will the stock muffler hurt the horsepower?

It can. We didn't map enough of the upper end of the VE table to tell by how much.

Sorry for no updates . I left Friday and stayed in the mountains for the weekend and just got back today . but i will have the o2's tom . But now i have to rebuild a transmission . Mine is slipping in 1to 2 and then i have no overdrive. But i will post a run will i get the o2's . maybe i can do a pull in it .

Sometimes they come out of it with a fluid and filter change. Run some Seafoam TransTune for a few hundred miles. Then drain as much out as possible by disconnecting the cooler return line to pump the fluid out. Keep refilling and pumping until clean and bright red. Those shop flushes where they douche fluid in and out through the dipstick tube can be damaging. Pumping out of the cooler line keeps the same hydraulic circuit path, so debris doesn't end up crammed in the valve body.

After that copy the Performance upshift pressure table to the Normal.

I will give that a try. But we have started to rebuild a transmission that i had that i wanted to bullet proof it . But ill have to wait for that . But i will run the transtune and see what it does. And fluss out the lines.
