what I should have got - with no instructions whatsoever, but those are lap joint clamps so I guess they go over the expanded end and over the header collector. Here's what showed up: They must have started the cerveza's pretty early on the friday they made these. Bring back american manufacturing! I could have paid $600 for this midpipe instead of 148, and it would have been made correctly. ..... That said, the headers are super nice, they are obviously made by the JBA "A-team." Unless they hit the steering shaft like the last chinese ones I bought. (china-mexico-usa would be the part buying order)... if they do I am selling these headers locally for $5 and parting out the entire car, buying that NC Miata I was thinking about, leaving it stock, then trading up to a new GT500 after everyone is finished jumping the dummy.* *I used to work doing tech drawings and fire plans for a hog farm operation, they had this dummy that they put pheromones or sow's urine or ??? on so that the male pigs would jump on it and get super excited, then it was someone's job to uh.... gratify the pigs into an insulated mug. There was a door at the side of the room that they would pass the pig juice thru, which would then be used to inseminate 100's of sows. The male pigs would get _super_ excited when put in the pen with the dummy, foaming at the mouth and making noises, just like youtubers, instagram influencers and lumbago afflicted baby boomers are doing right now at the sight of the 2020 GT500. Wads of cash will be flying for some time.
