mirob looks like we're probably in the same batch; some of our photos are the same too. Based on placement it's the same Midpipe. I understand the efficiency LOL

They’re making a bunch of midpipes. Also for SF Motorsport based on the photo they sent to me.. they’re on preorder through them at double the cost of buying your own direct.

Does anyone actually know if there are any actual differences between CSZ, SF Motorsports, or RES? Like the previous poster mentioned SF is like double the cost and RES seems to be around triple the cost of CSZ from what I got quoted.

SF Motorsports is 100% made by Boska.

The RES has the Z pipe in front of the under body brace closer to DPs. Which allegedly should give slightly better scavenging and minimal higher pitch.
CSZ, Yönristic, SF, and Boska have it after the under body brace.
Finish of Yönristic and RES is better IMO.

How do you know this for sure? And is Boska exactly the same as the CSZ?

Boska (Alibaba) sent me a photo of a Midpipe that was branded with their logo for the X4M. See my above post.

I don't believe Boska and CSZ are the same but honestly there's so many it's hard to tell who's making what.

Ironically the tracking I received notes generation in California and is under "FedEx Home Delivery" service which is traditionally for US to US packages. Beginning to wonder if it's actually warehoused here in the states at this point.

I could care less either way, as long as it eventually shows up at my house

Same. Just got tracking this morning. I was thinking FedEx is taking over in Cali once it arrives from China. I'll shoot my good pal Alan a message and ask. LOL

Ohhh sorry I missed the plate that had the SF logo on it haha.

I wonder if the RES design is also on alibaba or somewhere. They were quoting me like $1400 shipped to US. And saying that shipping costs were like $400 so pretty fair to assume they are shipping from somewhere else.

You should look at a previous post I made breaking down some of the differences.

In short, the key differences lie in the Z-pipe design itself i.e.
1. How long each section is
2. how hard of a cut it makes into the other line
3. What do the welds look like
4. Where exactly the Z-pipe section is in relation to the resonators
5. Diameter selected.

Most (if not all) on the market are 70mm or 2.75". I still think I am the only one with the 3" version but, because mine is more unique the overall "look" of the Z-section isn't that pretty. However, a couple people have heard it so far and almost all of them have said SLE3PER and mine's sound lower in pitch compared to Yonristic and the Boska variants.

I purposely have refrained from posting videos here to prevent prices from skyrocketing but, I have a couple now of me doing some Fly bys. Thank all the "influencers" and lurking "influencers" here who caught onto this and have ruined it for everyone lol.

Alan is the GOAT. I messaged him at like 11 pm their time and had a response in 5 seconds. Blown away by the response time to be honest. Better than ANY USA company I’ve worked with.

I think we're in the same shipment from china lol Ive been checking the Fedex app everyday since Alan told me it shipped.

Now im curious if he sent us the same pictures saying it's ours lmao.

I'll have mine on Wednesday unless fedex pulls a fedex and it actually comes on Thursday lol Until it says loaded on truck I don't trust their delivery dates on ground shipping. That might be local hub issue for me though.

I bet you're right but I think you're a smidgen ahead of me. My FedEX is still not giving me a delivery date.

I asked him why Alibaba is not updating tracking and he had this to say.

P.S. FedEx is the worst.

He sent me the tracking info on 3/30 and fedex had it in their hands on the 9th to give you an idea. I'm in Florida so she's got a long drive ahead of her.

Got the tracking info on the 9th so I'm a little bit behind you. 10 business days is moving pretty good...FedEX will probably take that long, too.
