- 5 feet of 1¼in ID Flexible Stainless Steel Exhaust pipe. http://www.summitracing.com/parts/wlk-40001
- ¾ in npt x 4 in nipple
- ¾ in npt pipe coupler.
- ¾ in npt x 2 in long pipe nipple.
In the photo it appears I cut off some of the threads of the nipple. I didn't, what I did do was grind the threads on one end so the nipple metal was thinned down to about 1/32 inch thick. This was so the sheet metal of the muffler and the end of the nipple were about the same thickness. This lesson the chance of too much welder amps needed to melt the nipple and not burn holes in the muffler steel.
