What are you guys doing for SCR removal?

Mrdeezy · 09-29-2015, 09:29 AM

Hey,
Was wondering what some of you guys were doing who had installed the alphabet delete regarding the SCR. I have seen unobtainium welding have an SCR delete pipe that is made to order. And Buzzken makes an scr delete for the x5 but not for 335d. I emailed a query and they responded a month or so until it it was available.

Are you guys getting custom pipes put on or just bashing out the inside? Does the swirl valve go too?

I live in California, and with all the vw smog madness. I want to have all of my bases covered just in case. So that means keeping my DPF and SCR just in case I might have to reinstall for a newer emissions test someday, or if I could not sell the car as is if I ever decided too, i could put it back to stock.

What is the general consensus on this?

The banned one is coming out with downpipe-back exhaust soon. That is what I'm going to use, and I'm keeping all my emissions crap in case I ever need to reverse it all.

Just wake sure you guys flush your DEF/Urea tanks thoroughly with distilled water to prevent any crystallization to avoid DEF/SCR failure in the future should you have to revert back to stock.

Yes good call on flushing the urea. And refilling it with distilled water.
I contacted Bohl for a dp price and got a message immediately back from a guy named Jess. Is it the same banned whistler guy by any chance?

Unfortunately downpipe-back exhausts are going to be a while still. But Bohl Diesel (Jess) can put a nice full exhaust together for you in the meantime.

Dave,

Not sure what you mean. A downpipe-back exhaust is a full exhaust, at least in my mind. Does he have those available now? We talked a couple of weeks ago and he had sent some tweaks to the supplier, so it there were none available.

GaryE30 · 09-30-2015, 02:53 PM

So Jess is making whole exhaust systems in the interim until the production supplier is ready?

He makes a very nice midpipe that utilizes the 335i gas exhausts for our cars. Its the best option at the moment until the production exhausts are available.

I just messaged him about getting the combo delete pipes. Thanks for the heads up.

Gearhead51 · 09-30-2015, 08:18 PM

Having done the first 335I exhaust system, I can't imagine a better sound or more power. I wouldn't think of it as a stop gap. I'll take you for a ride and make a believer or of you.

You were certainly not the first bruh, I had done mine last year and I probably wasn't the first either

......That being said, yes it does have a wonderful sound and solves the SCR dilemma!

Full exhaust with banned one's help. Storing all my smog equipment including my original stock DDE.

Gearhead51 · 10-01-2015, 08:40 PM

Iaknown, sorry. I didn't realize you hacked up a 335i system. I did mine on a whim to see if out could be done. I should have read your thread about it. Probably would have saved me a few hours with the tig.

Chief Orman · 10-01-2015, 10:40 PM

For a California resident it seems not worth it to me to do anything more than blocking the EGR given the hassle of reinstalling the DPF, etc. I am running a Racechip Ultimate and water meth and I have been able to get a BIG performance gain without the alphabet delete. That said, if I didn't live in CA I would do an alphabet delete in a heartbeat. I am going to get Jarek's stage 2 that is compatible with emissions equipment as well as a Wagner IC. Once I am done with those mods I'm going to call it a day on engine mods.
