I bought this set for my 1969 Road Runner with TTI383-178 headers. The mandrel bent 2.5" H-pipe kit was MWM6870. I welded the collectors to the headpipes. The tailpipe to muffler uses a standard muffler clamp in the hanger, the other 5 joints have band clamps which all come apart because I used antiseize. I installed a bung in each collector for an A/F meter. The mufflers are DynoMax UltraFlows with the extensions directly from TTI as an added cost over the standard Super Turbos. The tips are Accurate Exhaust Plymouth oval stainless steel and still look nice after 3-4000 miles. I cut 4 slots in each muffler outlet to get them apart as gently as possible, it would be easy to weld these back up. $550.00 picked up in west central WI, 100 miles straight east of the Twin Cities.
