Removed Stock Exhaust... is this normal?
 

Hello everyone, I have recently removed the stock exhaust off my '17 Toyota 86. Afterwards, I saw the end of the mid pipe had a weird bend. Pictures are shown below. Is this... normal? If not, I'm glad I replaced the exhaust system!

That kink is to get better clearance around the rear subframe/LCA area. My exhaust is the same.

There's a reason why your car costs $30k total. Things like these are offered to the lowest bidder meeting the manufacturer's specs and warranty requirements...

The parts say Subaru on them. XD

Thanks for the responses!

One thing about the automotive industry is that the manufacturer is usually just an assembly line.

The car maker may assemble individual items, however they usually don't make the individual components.

So things like engine blocks, transmissions, and a bunch of other individual items from injection molded plastic trim pieces, to shocks, to exhausts are all made by someone else and stamped with the manufacturer's logo.

Auto makers are really good at designing, testing, and putting together the final product. the individual components come from a variety of supply chain vendors, some directly owned by the parent company and others indireclty owned.

Totally normal. As said for clearance. There is a serious pinch in the over pipe...

Well, I'm glad the new exhaust system doesn't have such a pinch in the mid pipe. I still have yet to take it out for a test drive.

As someone working for a major OE supplier, can confirm.

Yep, cheapest bends they can. Honestly 95% of the horsepower-robbing restriction in the exhaust system happens before you get to that point.

As someone working for the same major OE supplier I also confirm.

And will add that one parts supplier can make parts for many different car companies side by side on the manufacturing floor at the same time. Some of those parts can be exactly the same with the only difference being a part number or a brand stamp. It doesn't matter that something has Subaru stamped on it they didn't actually make it.

the even funnier part is when I tell people "there's only like 5 major manufacturers of shock assemblies worldwide, aftermarket included" and they freak out...

to illustrate my point, here's the top 100 auto parts suppliers in the world. I think like 7 of them actually have a company name identical to an automotive maker...

Why is everyone bashing The OEM? That kink is intentional and not a manufacturing defect. I am pretty sure it does not cause a big power loss since most catback exhausts dont result in significant hp gain.

You dont see that pinch in aftermarket systems because they dont have as strict design goals when it comes to fitment and ground clearance.

No one is bashing the OEM system.

It's there because 1) the OEM piping is pressure bends (as opposed to mandrel bends for aftermarket systems), and 2) cost. I'm going to take a wild guess and say, the stock exhaust system probably costs around $50-75 to make.
