I've read through the whole thread and see people were able to get a GRWA system with the vacuum valves. I'm not seeing these listed on Alibaba. Can anyone hook up a new owner with a link or contact? Thanks in Advance!

Did you reach out to them? Also in the same boat. The GRWA picture shows electric valves. And I want vacuum valves.

I ended up ordering a system through midwestbimmersupply.com. They are all the same system and I got a great deal. If I went direct with GRWA it would have been like $800 plus $400 to ship and then duty fees. My kit i think was $1200 from midwestbimmersupply.

I might do the same.

I'm sticking with stock cats so needs to hook up to oem x.

Thank you for the tip!

Just an update for you guys that want GRWA. You can message 'Great Wall Automotive' on Instagram. A friend of mine did this and they were very responsive and fulfilled his order. I didn't know they did one-off deals like that outside of if you have a relationship with them, but I'm glad to hear they do!

Of all these valved exhausts available, which one is the quietest with valves closed?

I need quiet oem volume (or close to it) sometimes.
