Midori Down Pipe (90Mm) Custom Decat?

[NismoSTune]

Hello,

I bought a 90mm midori downpipe where I was told that I simply needed a custom decat pipe but I can't seem to find out... My current decat pipe is an 80mm tomei one so I'm not too found of modifying it. What have people done to match the 90mm downpipe to an 80mm exhaust system? Concentric reducer in the decat?

Why the Japanese exhaust part love?

You know 3.5 inch is pretty close. Is there a flange on the Midori?

[NismoSTune]

I don't think it was about the JDM love... I saw a shiny SS twin 80mm to 90mm downpipe for bigger twin turbos, so I got it but didn't realized it would be tricky for find a 90mm decat.

The midori outlet flange is nearly 4". I could probably get a 3.5" welded on I guess. Being from Canada, the options aren't always great for imports so I end up needing to ship.

You can buy reducers/expanders here, in 304, probably run you ~$30, 80mm wouldn't be typical off the shelf.

If you overcome the affection for the jap pipe, most any 2 bit, one man exhaust shop here can flare, as long as there's enough tube to insert the mandrel. 75 to 89 is common, 80 to 89 would be a piece of pee.

Awesome, I'll check around local shops... It's just titanium, I can go back to SS...

Nismo, make sure they only use titanium materials If you ever modify your pipes.

Anyone know if Japan is the only place to get titanium exhaust components for the skyline? I would love to save money but I believe only the Japanese make Ti bits for Skylines

[NismoSTune]

I meant that I don't have to use my titanium parts and just use custom SS.

I understood you, brother. I was just saying like a FYI to make sure you're aware
