The "S" bends coming off the headers were made by using 4 turn downs bought through summit. I slipped on on the header and clocked them then added another backwards. You can clock them to fit through the torsion bar cross member exhaust indents. They are the same as the turn downs coming off the mufflers. So I used 6 total on the exhaust. The 3 1/2 exhaust slips on and off the headers and the "S" easy. No clamps they are bolted together using tabs facing opposite directions with hole for 1/4 20 bolts. We were able to remove and add different length pipes after the "S" The car ran faster times with the full exhaust. 829 at the crank at 7900 RPMs using a 950 quick fuel on the dyno. The car picked up changing to a 1050 quick fuel.
The exhaust is off the car since the car was totaled in an accident and is not being reused on the new car. The headers are 2" tube hookers and have a damaged tube from the accident . The new car is getting 2 1/4 zoomies exiting the front fender for a alcohol/nitro mix engine.
The complete exhaust with the tail pipes and tips with hangers are for a mini tubbed 108 WB car . I have adapters for standard heads , W2 Heads , Batten or Indy heads . So this exhaust was used on different engine combos.
