Getting ready to start ordering some parts. thinking wagner catted dp, wagner intercooler and JB4.. target is about ~400hp at the wheels. I want to make sure I have reliable hp as this is a daily driver. anyone have thoughts on this setup/experience with wagner parts?

I have the Wagner IC and it's a great product, but right now there are a lot of cheaper alternatives and I think I would go that route. 3 years ago when I built my car there was no other option.

I also wouldn't do a catted DP if you are going to replace it.

+1 on catted dp.

I did a write up on my install of this IC as well and supposedly there is zero detectable difference between this one and the wagner.

For 400 WHP you'll need to do mhd stage 2+ and I'd skip the JB4. Just look up what you need for stage 2+ and you are done.

MHD gives crank HP numbers as far as I am aware. You will be around 370ish WHP I believe with stage 2+ since you also probably have an EWG car.

Why not BM3?!

Because some people like MHD. BM3 is definitely less convenient, since you have to buy an expensive WiFi agent or DIY one (pretty easy though) in order to use your phone. MHD was designed for mobile use from the get go.

Personally I use and prefer BM3. The WiFi agent is very cheap and simple to make, BM3 provides their WiFi agent image for free, and the only cable you need is an ENET cable.


Also, definitely invest in an aftermarket charge pipe. ER makes a good one and is what I use. There's been stories about people's charge pipes popping from the increased boost. It's a lot more of a preventative maintenance mod, but why run the risk?

I just ordered BM3 and will be tuning sometime soon. I live in Los Angeles where I rarely have the chance to go WOT. I got the tune for those ultra-rare moments when I find a bit of open road or when I'm getting on the highway onramp. Do you think I'll really need a chargepipe given how seldom I'll push the car and likely will stick to stage 1 OTS?

You should be fine with stock chargepipe... I ran JB4 on map 2 for about year and half on stock chargepipe without issues.

Stage 1 is safe with a stock charge pipe. They also state that Stage 1 is fine with everything stock. Stage 1 isn't just useful at WOT. It also helps make the power curve a little more linear and give the low end some more torque. Overall makes the car way more responsive.

Just make sure to run your first tune after a nice long drive so the battery is full charged if you don't have a battery charger/tender. The first tune takes a while because it needs to unlock the DME.

Stage 2 is where you need a downpipe, IC, and charge pipe.

Why no to the catted dp? I have seen a few vids of catted vs non and the sound is cleaner on the catted ones… Does anyone have some sound clips I can check out?



Thanks for all the replies and info, helps with my research. Was planning on upgrading the charge pipe too once I was putting everything on. Will look into the BM3 some more.

I would imagine it depends on whether or not you have smog checks.

Wouldn't a catted DP still fail smog? I remember seeing something on YouTube where a dummy O2 sensor was still needed with a catted DP.

[ziekxq]

All you need is o2 bung and that will do the job with catless pipe.

Don't think you will pass in Cali like that

[ziekxq]

Well if they look for smell and physically check the downpipe than yeah you will fail. Otherwise, no problem passing.

Yup. ANY change to the intake and exhaust until the cats is a fail; UNLESS the part has a CARB certification sticker. The guy that did the smog check on our 2012 spent around 5 minutes searching under the hood.

[BimmerHausPerformance]

In TN they only do a visual... and they have no idea what they are looking for, and check for engine readiness through the computer. I had no issues with a catless DP and simply using a tune or other methods to get my OBDII to read OK for the readiness check... all depends on WHAT kind of inspection/smog check they do in your local area.

[ziekxq]

They only plug obdii and check for emission... I passed so far twice with Catless downpipe.

[ThaiBruin]

Just came back from a trip and flashed my car with BM3 Stage 1 OTS (91 octane, boooo California). This is by far the best tune I've used so far. I've had a JB4, a Dinantronics Sport Tuner, and this is the best of em all. Absolutely no peaky (sometimes unpredictable) power boosts, and just a lot more oompf throughout the powerband.

The only thing that I'm trying to figure out is burbles. I can't seem to hear any, and it was my understanding that you'd still get burbles even without any additional mods. I do have an M Performance exhaust, but nothing else.
