Here's a direct link to the vendor's page: Jiangxi Boska Trading Co., Ltd. - https://bskmy.en.alibaba.com/index.html

and here's the link to the one I bought - https://www.alibaba.com/product-deta...920077412.html

Thanks again. Sorry to bug, just excited to hear it. Think I’m just going to bite the bullet and order a TI from them.

No problem. They usually don't start working on it right away so you should have some time to switch if you change your mind.

Make sure you ask about increasing the diameter of the pipes. You can also pick what tips you want. They showed me a catalog with 6 different designs but I'm pretty sure you can customize them however you want. They might charge extra though.

Any updates?

Placed an order for a full Ti from that vendor above. Really good communication as the other user said. They gave me a time quote of about 20 days and it came out to a little over $1800 with shipping for one unit. I also increased the pipe size as the other user recommended.

I have an AA catted down pipe so I’ll try getting it installed and upload some sound clips asap so people get the chance to hear that combo.

Exciting! Congrats!

Just got mine put on yesterday and I’m blown away. Way louder than my previous AA axle back with the valves open and as quiet as stock with them closed. Tips look wayyyyy better as well, a lot smaller and don’t stick out half way past the diffuser. Best part of all is there’s zero drone and I’m catless, it’s crazy. Will post some clips when I get some.

Got the stainless one, the shop said the fitment wasn’t the best, but nothing too bad. No leaks or anything.

Not at all, it's been perfect but I am selling the car so everything is coming off.

Whysitcold · 04-10-2024, 09:36 PM

Just an update for anyone who is following. Placed my order on March 12 and received notification that my exhaust has been completed and is being shipped to me. ETA is about a week, I will attempt to have it installed asap and show you guys some sound clips.

Cheers!

I’ve made a review comparing the Ali baba exhaust and the AA axle back system titled “Ali baba exhaust” if anyone was interested.

Thanks for the review. I have the AA as well. Tempting, but not sure if it's 304 stainless (they just say "stainless"), so may be more prone to rusting in the rust belt where I live.

It says sus304 in the description. According to google there’s no big distinction.

Thanks. 409 stainless is more susceptible to rust. My clamps are 409 and they look bad.

It's great to know that they're cooperative. Please keep us posted once it arrives and you've installed it!
