Heck yeah man. Almost there! Glad to hear it fired right off, get the pipes on and post up a video of the sound.

Removing old exhaust. Both downtubes and cats same diameter, just going to put coupler on and not weld. Hard to find shop close that welds stainless. Should have it pretty close today. Will definitely post after getting it done.

So still running factory muffler and tailpipe?

Put magnaflow catback on, hanging loose till I get new headers. The black cats were for a two wheel drive. Got under there to put the down tube on and it would run into front driveline. It’s ok . Took the headers off today, this will give me time to put catch can on. Chomping at the bit man. Maybe this weekend. Getting the original flanges welded back on to y pipe. So everything will look stock and bolt right on to new headers.

Got ya pipe back from welder. Nice job. Quick turn around. Mounted catch can. I might spin it to face towards firewall. Just waiting for headers now.

Whoa headers came today. Hurried with catch can and then installed passenger side header. Have to wait for dip stick tube to show Friday. Will install rest of exhaust tomorrow. I'll go back and redo hose for catch can from on top a little wonky.

What did you have the Y pipe welded for? I looked back through the thread and must have missed why it needed welding

 

[RobsFreeland]

I couldn’t get the nuts off. Even after I removed exhaust manifold and in vise, soaked with pb still had a bear of a time getting the nuts off. So I thought I was not going to use that part (flange) anyway so I sawed em off.
Should have other side (header) done today and y pipe mounted. Dip stick needs to be replaced. I’m going to fire that mother today.

 

[Mudsport96]

Ah gotcha.
Almost there, glad its moving right along for you
