Revisiting some ancient stuff !!
I built my H pipe over the Christmas/New Year holiday time when my wife 'suggested' that I keep the noise and dirt pollution down a bit. Actually turned out fairly easy once I got the @#$% exhaust system apart (I tightened everything with an 18" bar)

What I have are a couple of 8" long spool pieces of 2.25 pipe with the exhaust pipe end belled and the muffler end to fit inside the muffler. I dug out a 180 degree mandral piece of 2", cut it to size with a 2 1/16 hole saw( couldn't find my 2.25) which with the normal hole saw wobble, was just right, and notched the end. I opened up a 2" hole in my 2.25 spool pieces and welded it up. For whatever reasons, the welds look like bird droppings - and the welder was spitting - so had a bit of clean up grinding to do. It will all be bolted back in place tomorrow (we both had the flu and stomach problems hung on for 3 weeks)

Dave very interesting, gives me some ideas. It looks like the crossover pipe has a slight U-shape. I have had some Christmas visitors and also some professional obligations relative to my previous academic career but the good weather rekindles stuff I was putting off until April or so.

Don,
The pipe was cut from a Summit mandrel 'U' to go beneath the driveshaft as I have my exhaust tucked up as high as possible. I'll post an "as installed" photo soon - I need to pick up a piece of .500 stock and make a muffler hanger today. This needs to be welded directly to the muffler as I can't move the rear hanger.

Our good weather came to an end yesterday with cooler weather and a <.25 dusting of snow(we've had < 1.00 total so far this year, about 18" less than normal). I've not been too diligent with the car, with the flu and the holidays slowing things a bit, but am back to work at it this week.

My professional obligations, with the exception of a few phone calls ended as I walked out of my office for the last time 18 months ago. And I don't miss it. But still not sure that if someone made me an offer that I wouldn't do something similar, at least parttime, but not for GE.

And installed:
What a project it turned out to be -
Also shows my new Denny's HD driveshaft

Hi Dave,

This looks good! Did I miss any discussion of choice of mufflers?
