Guys I have an Akra on order and unfortunately exhaust and tips have separate shipment times. I should receive the exhaust within the next few days but tips will take longer. I wanted to see if anyone can help with tail pipe specs or exact tips specs so I can use something generic or makeshift for now until the actual tips get delivered. Some close up pics of tailpipe without tips and OD measurements of pipe would be great. I would hate to install it without any sort of tips but don't want it sitting in garage just because of no tips as well.

I understand the tips and tail pipe have Akra proprietary design and not any tip would work but I might be able to do something with some customization on generic tips until the real deal arrives.

Any help in this greatly appreciated.

Thanks

This same scenario happened with one of the guys in a group buy for our Remus exhaust. The tips took forever to come for him. He ordered knock off tips from AliExpress (like 95% cheaper lol) while he waited. I believe they fit fine and looked great. I'm fairly certain you could do the same for Akra while you wait.

Unfortunately I’m gonna have to do the same thing as the person you’re talking about. Quick question about the Remus exhaust — do you know what size the end of the exhaust (without the tips) is? Their spec sheet says the pipe is 84mm but I’m not sure if it tapers off at the end.

Alternatively I can use my current MPE tips on it, does anyone know if it would fit?

Thanks.

Thank you! Should I size up a few mm if I order that inlet size (like order 63mm) or do you think 60 will be fine?
