2.0L RV6 Looking for 2.0L Downpipe BETA Testers

[a c i d.f l y]

Only special tool you'll need is the socket for an O2 sensor. It's one of the most standard. 7/8" 22mm, about $10 at Autozone?

If you don't already have a torque wrench, it's not required, but suggested. What I'm about to say sounds scary, but extremely unlikely, if you over torque by hand you can snap off a bolt into your head and that's a huge headache to remove. Just tighten til it feels reasonable/doesn't move. When I used my torque wrench they were already perfect.

Thanks for the details! I already installed mine ASAP the other day (and experienced some complications such as spilling half my socket set into the engine bay and later stripping the cheap 12mm socket I had and having to run to Lowes mid-installation to grab a new one), but your post will certainly help people doing the same thing in the future!

This is the video I followed (it's for the catless version, but everything still applies just the same):

CEL has gone off and on two times in the last week. Seems to be about 2-3 days off, 2 days on, 3rd day its off again. *shrug* Kind of annoying. Need to run some logging to provide to RV6 for analysis... It's definitely the second O2 sensor flagging, though. Not sure if it's rich or low flow, need to pull the detailed code report.

Do you know what code you are getting? Might just take a little tweak of defouler to run code free.

Yup. Second O2 sensor.

 

[RV6]

Yup. Second O2 sensor.

Try giving the defouler 1 turn in to pick up more exhaust gases. We ship them 2 turns out.
1. Remove O2 sensor
2. Loosen jam nut on defouler
3. Turn clockwise 1 turn to get it deeper into O2 bung.
4. Tighten jam nut
5. Replace O2 sensor

My CEL has been going on and off as well so I really appreciate the suggestion- I'm relatively noobish at these things so pardon my poor use of terminology, but can you please confirm whether I'm correctly understanding the components you're referring to in the pic below?

Also, mind specifying what size wrench i'll require and whether I can turn the jam nut and defouler without removing the entire downpipe?

Thanks so much in advance!

So just to update: I figured it out and fortunately it turned out to be very simple and there was enough room to finaggle the wrenches to remove the O2 sensor and loosen the jam nut enough to turn the "L" shaped thing once clockwise - so It looks like the answers to my above questions are all "yes".

Afterwards I turned the engine on and the CEL light was still on, but I'll keep my fingers crossed it hopefully goes away soon.

Yeah hopefully that helps. Mine should be in tomorrow. So I will be installing mine soon. I guess I’ll have to adjust mine before I install it? I’m not sure how to approach mine.

I actually wound up resetting my ECU by disconnecting the battery (both terminals) for 30 mins and the CEL light was off when I turned it on afterwards. I just hope it stays that way lol. If not, I'll give the defouler another clockwise turn and keep doing that one turn at a time until hopefully the CEL stays off.

I recommend tightening the defouler like RV6 suggested before installing the downpipe since it seems the CEL is expected to come on if you don't. Even if you do it after installation, it only took me a few minutes to successfully tighten it so it doesn't really make much of a difference unless it's torqued down excessively and you need more wrench clearance to un-do it.

I can update if the CEL comes back on again in case 1 turn isn't enough.

Well my RV6 catted downpipe shows it is on the fedex truck on its way to my house. I’ll take some pics when it gets here. I won’t be able to install it though because I dropped my car at the shop to get my spoiler painted and installed earlier and will be a couple days before I get it back. But at least I’ll post the condition of the downpipe and how the ceramic coating came out.

 

[mvela]

Ok well here are some pics I took of the RV6 downpipe. I tried to get enough to show how awesome the craftsmanship is on this part. They really got a lot of pride in their work! I could say it’s damn near perfect. Now the fitment I will have to do an update once it’s installed. But for a visual inspection, it was properly wrapped with bubble wrap and paper to make sure it gets to where it’s going without being damaged. The welds, ceramic coating, and assembly look great. But anyways here are the pics

and in case anybody was wondering, yes that is light you can see through the catalytic converter

 

[long_meats]

All right, so unfortunately I have another update regarding the CEL...it came on again. I went ahead and turned the defouler clockwise for another full turn and reset the ECU so lets see if that helps.

Yeah keep us posted please. I’ll be installing mine next week. I don’t know if I should keep my defouler the depth that RV6 sent it, or go ahead and give it a clockwise twist right off the bat?

Didn't wanna make a new thread so just gonna post this here. There's dyno results for thr catless downpipe, but are there any plans to dyno test the catted? I want to see how much power I can expect to gain before I drop money on this.
