Do you have some pictures of your stack? I need some ideas. I want to straight pipe but keep the top stack and heat cover all in their original places and angles.
I will take some pics. in am.I cut the muffler out,reused the top pipe,and just welded the original muffler flange[clamp type]on bottom.I still retained heat shield.Has a deeper tone,but not my neighbors hate my truck loud.

Hope this helps.
I cut muffler section for bottom clamp attachment,added straight pipe,and welded together.
I measured muffler length so stock height would be retained.
The factory heat shield can be used with no mods.
Be careful when removing muffler,it is heavy/awkward.
Good luck

OK...So I had a few minutes of quiet time this week so I ordered parts to straight pipe my 923A2. Could not find anyone to bend 4" pipe so here is what I did. Quite painless and only about $160.
2- 45 Degree 4" elbows from NAPA #EXH41632
1- 10 foot piece of 4" exhaust tube. Why? Cause it only comes in 10 foot sections and was $60 with the online coupon. NAPA #EXH49012. Just make sure you order QTY. 10.

Take your time...grind the weld off the top (the curved exhaust that is on top of the muffler) where the flare is. Use the flare on the one elbow where it replaces were the muffler was. Line things up to see what angle things are looking like. I cut 1.5" off the top section of the first elbow. The one the flange/flare goes on the bottom of.
The top pipe (straight one) I cut at 42" high.
Welded the sections together with my little Mig welder. #3 power #4-5 speed.
Clean up the welds, wipe with paint thinner, paint with high temp paint...still need to get this part done.
Will share completed photos when I have another me day!!
