I just received my Remus *sport* axleback today, and measured the OD of the outlets with a digital caliper.

The min and max OD’s, as measured across all four outlets are: 59.49mm/2.342” to 60.35mm/2.376”

-Ash


EDIT - based on the min/max Remus outlet OD specs, the custom exhaust manufacturer recommended I go with 2.380" ID tips. Once I get them and fit them I will report back on that.

The 2.38” ID custom tips fit perfectly onto the Remus exhaust. I highly recommend going the custom tips route if you are getting a Remus, given how stupid expensive their tips are.

I paid $75/ea for these. Website is www.42draftdesigns.com

These are exactly my thoughts.

So I ordered some generic carbon tips off eBay to replace the Remus race stainless steel tips. I was looking for something close to the OEM look with not much of a big diameter as the Remus tips. So far I am satisfied. The inlet was 2.5in total length was about 162mm. Although I might order tips with a total length of 170mm to allow them stick out more. The seller on eBay had different diameters and different lengths and it came straight from a factory in china 🤷🏿*♂️

They look good! I almost bought those same tips myself! I prefer the all-metal look for my CS since it looks closer to stock.

How much did you have to crush the 2.5” tip inlets down onto the Remus outlets?

Not that much tbh. The inlet has a lot of room for adjustment so the tips fit well and after tightening them the aren't going anywhere.

Thanks. While I was waiting on my custom tips to be built, for giggles I bought several Amazon 2.5” tips to fiddle with and they were all way too loose for my taste. Maybe these all have some variation to them.

FWIW, I am not happy with my Remus back box at all though. The fitment is terrible and I’m likely going to have to go with something else…

Yeah I had so many issues aligning the Remus race box cos it came in so many pieces. Coupling it with the AA EL midpipe was a different hassle.

I have the remus race exhaust with non remus tips,

I have tried both and can confirm that the 60mm inlet diameter works perfectly for mine, tried the 63mm also and it was a tad too loose.

Make sure you get an exhaust tip with enough length or it sits too far in.

For reference the tips I'm using are

Length : 175mm
Inlet: 60mm
Tip Size (what you see) = 90mm

Installed my Remus race exhaust this weekend. Just chiming in to say this is the right spec to get. Ordered some MP replicas from AliExpress for $200USD and they fit perfectly. Any shorter than 175mm and the tips won't stick out enough from the rear diffuser.

(Look at the fitment on the right. I know the left side is off in this pic, I have not had time to adjust them yet.)
