Also interested. Have Euro headers and planned on modifying section 1. This seems like it might be a lot easier and ready to go. On their site it says O2 bungs welded in but I don't see them. Always concerned parts won't fit correctly (no experience with this vendor just a general concern) and what is supposed to be easy turns into a hassle.

If I remember right the complaints on these revolved around ground clearance. They hang a little bit lower due to their shape. I think there's a couple threads where these were tested out on a few different Moupes.

Say you do a euro header swap, picking up a 400 cell for the s-pipe is pretty dense don't you think? I'm not sure how much OEM is (I think 200 on the headers and 200 on the s-pipe) but it seems to me this is pretty much equivalent to buying euro s-pipes.

Besides the density, there's also the cat length. Euro cats are huge. North American cats have the same material, but less of it, so they should flow better.

I just got off the phone with StatusGruppe regarding the 400 cell cats. They said because they're high flow, it pretty much guarantees you won't pass the sniffer test but you should pass the plugin computer test. Which that is my main concern because the sniffer and visual you can just "find a guy" for.
Here's the interesting part, they actually don't recommend this for our cars. Two reasons, they don't provide much performance since the cat itself is massive, and apparently, they're made for V8's? Didn't get exactly what he meant, my boss was walking around while I was on the phone I wasn't paying full attention lol. |

FWIW, CPI shipped me a prototype set of cats for the DKF system to make sure they pass emissions. CPI can also make sniffer-compatible attachments. So if someone had a rental set of California cats, everyone could run the high flow cats for everything but the sniffer.

Maybe I'm having a long day at work, but what do you mean by "rental cats"? And any time frame on when this will be out? |

CPI has built me a set of 400 cell cats to pass OBD2 readiness. However, for smog testing, CPI can put in 400 cell California cats that are more restrictive (and expensive) but should pass sniffer.
By "rental cats" I mean that someone could purchase a set of California cats that fit the DKF system, and charge a set amount (like $50 plus a refundable damage deposit) for people to borrow the cats to pass sniffer. Once sniffer is passed, the cats are returned to the guy that actually owns them, and the deposit is refunded. Customers could always purchase their own set of California cats, but that's a lot of money for a test that occurs every two years. As far as timeline goes, CPI has made a jig to build catted attachments. If someone wants to test the DKF/CPI California cats, shoot me a PM. I can get you a prototype set (which won't be as pretty as the final product) for a significant discount. If you don't already have a DKF system, I can get those too. DKF wants to move their last few remaining sets from the last group buy, so I'm sure they'd be more than happy to do a resonators only system (plus the CPI attachment). By the way, DKF is onboard with all of this, and they want to have a solution to the CEL before the next group buy.

Lol yes, very true. There's also a huge volume difference in part and full throttle with high flow cats. I still have the OEM setup on my ESS car (which will change next month), but with my G-Power car, I have Supersprint V1 stepped headers and HJS catted S-pipe. The difference in volume on/off throttle is insane.

We can even chip in for a CA "rental" setup with everyone that's around the area and just pass it around when someone needs it. Like a slut. |

Next time I have to smog, I'm plugging the o2 bungs on my DKF Section 1, swapping in the US header, and taking it for smog that way. I'm interested in a 400-cell, smog-passing aftermarket cat that can easily swap into the place of the DKF 300 cell cats, but I'll believe it when I see it. I've never seen an aftermarket cat easily pass smog in good 'ol CA. |

Or just swap ECU's with a stock ///M so the computer thinks it's YOU that passed the smog test. Don't listen to me I'm just bored at work. Last edited by UntzUntzUntz; 03-24-2015 at 07:07 PM.. |

Tunes do exist that show secondary O2's as ready. It depends on the state, but there is a $10k fine around here for getting caught with such a tune.
The proto 400 cell cats have already shipped out to the test car, which has stock tune, AA headers, DKF S-pipe. CPI has offered to make the California cats, so if someone is interested and has smog coming up soon, I can get a set built. The cats are a lot more expensive though ($200+ more per set).

I should be getting mail for my smog testing in a couple months. I could be the test car for you so if it passes, I'll take it off your hands. PLEASE try to have the pipe at the larger diameter right after the cats. More flow while having zero effect on emissions. Btw I can coop euro headers with it. It's collecting dust in my garage just waiting for a CPI s-pipe to mate with. |
