Riss Racing Catless Downpipes.

[Humtek]

Currently the only catless pipes that are available for us XI guys are the UR pipes. Anyone interested in getting RR catless pipes for their XI? We need a few guys that will be dedicated to start off to get these things produced.

According to the ModBargains site these fit xi? I have no idea...can someone comment on fitment? I might be interested if it helps get them produced if they don't already fit.

No,

The Riss Racing Downpipes are specific to the 135i/335i. The application is much more different on the XI version. If we can get a few, not many, just a few people interested, we can go into production for you guys. Humtek has been more than helpful and we want to get this taken care of. I just need a small head count and we'll take care of this for you guys! :thumbsup:

bump for the work week ;)

[Humtek]

bump for the sake of bumping. I want RR pipes for the XI.

[335iheLLraiseR]

this might be ethically wrong, but why don't you just buy a set URs?

[Humtek]

I have no problem buying from UR, but I personally prefer the RR pipes.

[longodj]

I agree

[fucema]

I would join up on this list however I cant justify catless DPs given the strict emissions standards in my home state (Virginia).

I severely want catless DPs however... but I must be able to pass emissions inspections here.

[Humtek]

Well luckily in my state we don't have emissions except for if you reside in Albuquerque city limits and even there they only do an OBDII check, not the sniff test. Even if you failed the OBDII test I've heard you could easily drop a $20 on the ground and they'll look the other way. :D

Why? What are the differences?

Our downpipes start at 3" for maximum flow from your turbos. Slowly tapers to 2.75" then to the 2.5" flange to fit any stock/aftermarket system. UR is straight 2.5" throughout.

[sapperelite]

Really glad I read your post, I was considering adding myself to the list. I am going to register my car in Michigan for the first year until I get out of the Army and then will have to register her in VA...

Thanks Adam. Also I might be wrong, but from the pictures I think the thermal coating that RR does looks a lot better then the job UR does. Even though you don't see the pipes, but if thermal coating isn't done right then what is the point of paying for it? BTW if these get made I would opt to get mine thermal coated. :D IMHO one company does quality while the other one does quantity, but thats business.

[quickspeed6]

Has anyone heard of these guys they are making parts for the 335/135 as well and i think they are in the process of making the DP the 335/135 as well.

[Humtek]

I have heard of them, but do their downpipes work with the XI?

Back on topic...

Bump! :D

[munters]

I would be in as well, but catted.

[jpsimon]

UR makes wonderful products for Suby's... so i trusted them for my UR catless downpipes on the XI. The product is wonderful and I definitely recommend it for those wondering..

Well if we don't get our 10 and RR decides to not make them. I'll be probably picking up the UR pipes as well. I'm in no rush at this point, but would like to eventually put pipes on.

I agree

no, man. i meant buy a set of URs in order to get the bends correct for fitment, not that should buy UR and not RR.

[Adam@Riss Racing]

Let me know if you guys have any questions at all. There's 2 people in interested and we're just looking for a "few" more. If we can't get 10, can we get 8?

[Humtek]

no, man. i meant buy a set of URs in order to get the bends correct for fitment, not that should buy UR and not RR.

Good question.... RR?

Adam,

I wish we could even get 5. I would of thought more people with XI's would like to have options.

[BES335xi]

how much will they run for?

[Humtek]

how much will they run for?

I'm guessing as much as their regular catless pipes.

[Adam@Riss Racing]

how much will they run for?

Well, we can probably do some kind of discount for the first group. They will not run anymore than the current sets, thats for sure. If we can get 10+, we may go cheaper.

[vase330]

Yeah just wondering if the catted ones wont be able to solve VA emissions issue for those who want downpipes.

Although our downpipes may pass emissions, they are for "race use" only. The N54 motor runs extremely clean, so we aren't too worried they won't pass the sniffer.

Not very knowledgeable on this. Just wondering if it is illegal or just not allowed by warranty. I mean if you pass emissions not like they are going to go under hood and verify its OEM pipes. I doubt they even know what stockers look like.

Also you cant see the stock downpipes. They are covered by the schroud.

[Riss Racing]

We need a test car local Irvine, CA. We will knock these things out and get them going for the people that want them. I will replace their 335xi with my 335i during the process. It will most likely take a few hours. Thanks!

[flukey]

damnit i wished in ca

[Humtek]

Me too... I live like 12 hours away :(

[Humtek]

bump

[Humtek]

bump for hope.

[longodj]

what's going on with this? No xi's in California??

[Humtek]

Guess not. :(

[xkactetx]

I'm intrested in the catless down pipes you can put me down +1
How much horsepower, torque can we expect to gain

[jpsimon]

why wait? just get UR!

[Humtek]

bump for hope.

[Riss Racing]

Modbargains is getting us the test car. We will have them done soon!

[longodj]

Yay! Good work guys, thanks for providing ANOTHER quality option to the xi community!

Modbargains saves the day again! Hooray Modbargains! :bow:

All we needed is the test car. For some reason it is hard to get in So Cal...:confused2

lol...that's cause in So Cal there's no "need" for an xi, even though I still think that an xi will beat an i on a twisty road coarse with the same suspension (aftermarket...like V3). That's ok though, you got one now! Woohoo!

Awesome!!! So glad to hear this.

[Humtek]

Adam,

We have a rough ETA when they will be completed?

[cgillio]

Please add me to the list for the Catless DP.

[Mrbig]

Just about to buy a 335xi sedan which downpipes would be best and which exhaust would be best.....

Your going to get a lot of different opinions on the exhausts for sure. Just pick the sound that is best. :)

For the downpipes there is only one maker for the xi and it's UR currently.

Any updates?

[cgillio]

Whats the status of the DP?

[Humtek]

Waiting on modbargains to get them the XI they promised.

[BES335xi]

No updates......Grr!

[Humtek]

Their still waiting on a XI in Cali. If your in Cali and you have an XI call or pm Riss Racing.

[ChuckBimmer]

Those look really awesome. I will have to get these once my warranty expires. :D

[Mike@IND]

i'm sure Riss Racing will come through with an update for you guys soon. either way, they are definitely worth the wait! i've got the catless coated pipes on my personal car and i love 'em. :)

[Riss Racing]

Hey guys. We cannot for the life of us get our hands on a 335xi here in So Cal. If you know anybody let us know!!!!!!! Modbargains never got the car over to us, and we cannot find one. We will need the car for 1 day! That is all. Then we can get these XI's taken care of!!! Please PM me, email me Anthony@rissracing.com, or call the shop line. Thank you!

Anthony,

Do you know anything about the O2 simulator and Virginia emissions testing?

I believe here that they do not actually test at the exhaust, but they connect to the ECU and read the O2 from there as they run the test. If it passes, then you are 'ok'. They do this for all vehicles newer than some year (not sure which year it was).

So I think it's a matter of whether or not the O2 simulator is detected. Is that thing obvious when you look at the engine bay? For that matter, does it read like something that would look reasonable, or do you get 'unrealistic' O2 readings? Would the mechanic notice?

edit : This is rather unfortunate... because I'm sure the car would pass easily if they just tested at the exhaust pipe... Every time I test my old honda my readings at the pipe are under 10% of the limit. The 335 would pass *easily* with primary cat delete.

I know if they looked in the engine bay to find the simulator they wouldn't be able to see it unless they actually got into the ECU. I'm guessing they hook up to the OBDII port and check for O2 readiness. In that case I"m not sure whether or not the RR O2 sim would give them the readiness ok. I know the Procede had that problem, but a simple firmware fixed that issue. I'm sure RR works fine, but I'll let them chime in on that.

Procede has a built in O2 sim? And it works well enough to pass for the real deal?

-scheherazade

It isn't built in anymore due to legal reasons. I know it will pass because many people use their O2 sim diy that live in Cali. If you already have a Procede might as well save your self a $100 and do this. Then again if you buy pipes from RR I believe they give them free of charge.
