- - NB exhaust on an NA? (https://www.miataturbo.net/general-miata-chat-9/nb-exhaust-na-7242/)

I actually searched for NB exhaust fitment on an NA, which dug up this thread. I'm throwing a stock NB exhaust on my NA to quiet it down.

Here's what I found:

1. Resonator didn't want to fit without hitting my PPF, so I straight piped that.
2. The hanger in front of the subframe is on the chassis on an NA, but it's on the front of the subframe on an NB, right above the front eccentric. It's attached to the resonator so cutting it out helped with that.
3. The single hanger on the driver side of the NB muffler is about 6" further outboard than the NA.
4. The two muffler hangers on the passenger side actually mate up, but my poor fitment (slash and weld) makes them fit...poorly. So I can't comment if they're correct if and when you actually spend time to fit it properly.
5. Small issue, but I think the NB bumper sticks out further than the NA, so the tip sticks a few inches further out. Looks a little funky.

I'll try to get pictures of all this tomorrow while it's still on the lift.

Rofl.

Don't know if it adds any, but it will fit. Just needs new hangers everywhere. You can even leave the older NB ones in place.

I know this is old, but I'm not the one bumping it. I just put a NB exhaust on my NA. The 2 mounts by the tailpipe are really close, just beat them a little with a big hammer to line them up perfect. Use a universal hanger where the exhaust comes through the subframe. Then weld a hanger to the exhaust where it mounts by the rear of the transmission. I used stainless threaded rod and it helped adjust the exhaust side to side a lot.

I apologize for ever creating this thread some 13+ years ago.

Apology accepted. Your build thread is a pleasure to read. Thought this
might be interesting. Oh well. :likecat:

Sorry to bump this thread again😅 but I still couldn’t figure it out. Nb headers will bolt directly to a 1.8 na head correct?

Please let this thread die. Shit, I'm surprised I'm still alive even.
