I have a speedwerx adjustable fat daddy pipe for an M8 for sale. It is ceramic coated and has two stingers- one for above 5000 ft and one for below 5000 ft. the pipe comes with a y-pipe and requires a fuel controller. I have a Power Commander V and an autotuner to really dial in the fuel mapping. It takes a bit of tweeking but when you get it dialed it will make your M8 run like it never has before. All the components have less than 700 kms on them. I now am on a turbo so no longer need these parts. The parts cost over $1500 US but am asking for $1000. obo
