Hello fellas,

I am currently running stage 1 93 octane map on my 2012 335i PWG. I'm currently getting 330HP and 400TQ. Would getting a custom tune help me boost the HP?

I have VRSF charge pipe. Don't want to delete the cat because I already have eliminated the resonator. Deleting the cat would make my car really loud. And I'm not a big fan of loud sharp sounding exhausts.
Merc v8 or e92 m3 exhaust sound is something that I would love to hear on my car. But unfortunately I haven't heard a single n55 exhaust even close to those.

Get a catted downpipe and/or a upgraded turbo. Then the tune.

You should also consider getting a new fmic

I have resonator delete and a catless dp. I had resonator deleted first. the catless down pipe barely made it louder. no drone at all.

Really!
There are different diameter of downpipes. Would you happen to know which one makes the deeper sound? 3" or 4" ?

Thanks

Thinking of buying a f80 m3 in couple of years. So wasn't planning on spending too much on this car.

lol then you can't have it all. The custom tune may squeeze out a little more HP

Agreed, I have a muffler delete and while there IS drone, the addition of a catless downpipe really didn't make that much of a difference, except the pops/ burbles seem to be slightly louder. The turbo really does a good job of quieting the car down.

I have a feeling getting a custom tune might leave you wanting more. If you're talking a remote tune, it's going to likely be cheaper than a dyno tune, so that might make it worth it to you. However the benefit is probably not necessarily going to be a lot more power, but rather a smoother powerband and better driveability.

For whatever it's worth, I'm running BM3 stage 2 with VRSF catless downpipe, CP, and intercooler, and my exhaust note is relatively deep. I know that raspiness that you're talking about and I don't seem to get it with my car. I'll take a video later today and post it up so you can hear.

Look at it this way -- for a custom tune you're likely looking at between $300-$1000 depending on which tuner you go with and whether you get it dyno tuned in person -- but for $300 you could also get a VRSF downpipe and stage 2 tune license for your BM3 and get a substantial increase in power that way. Your IATs should be fine without an intercooler as long as you're not tracking the car or constantly going WOT.

I got the wagner catless down pipe. I have pwg so its 3.5 inch and opens up. the wagner is the thickest of them all at least for pwg. which gives deepest sound. er was the second widest option. go catless

[13blk335ix]

I got the Wagner catless downpipe. it is 3.5 where it bolts on and then it opens up. it was the largest option for pwg (sent twice because I thought it didnt send the first time)
I had just a muffler delete before everything. lasted 2 weeks. drone was unbearable. it may have been the shop I got it done at though. I'm basically straight piped to stock muffler and I still think its quiet. tempted to grab an axleback

+1 for getting a downpipe

[harkes]

Stage2 93oct.........? You can run that without any hardware upgrades if you dont do 1/4 mile, street racing or other stuff like that.

[DreamerJoe]

another +1 on getting a downpipe. if you think putting a downpipe in will be too loud because you did a resonator delete, put the resonator back on.

Wouldn't that affect the longitivtiy of engine ?

Pretty much everyone says it's mandatory to have fbo for stage 2.

Depends on how you use the car. If occasionally do a highway pull and dont go on track days every weekend then you'll be fine I say. It is never black and white. With the Stage2 map itself you already put more load on everything decreasing longevity.

It's kinda too late for that. Exhaust shop got rid of the resonator.

gotcha.. what about an aftermarket resonator? I've heard good things about "vibrant" resonators. you can always go with a catted dp like "13blk" said, it's barely louder than it was with the resonator delete, but some can get pricey.. decisions decisions..

Still waiting for that video mate

And I just bought a cat less DP. ( never thought I would buy one. But the damn pricing was too good )

I'm drawn more towards AWE axel back.

Sounds so good ( at least in YouTube videos).
But these things are getting EXPENSIVE now. Lol

I tried.
Car was no different than stage 1.

Going to stage 1 from stock was a BIG difference. So my judgment for stage 1 to stage 2 can't be that off.

Stage 2 definitely is more stress on the engine. But here's what I think.

Since I tried stage 2 with oem downpipe. Engine made no significant change in terms of power. ( literally none at all )

The oem downpipe is so restrictive. I think it was next to impossible for engine to exhaust out. So running stage 2 with oem DP is only putting more pressure in the engine. But letting engine exhaust more easily would help engine to run and function better.

Just my 2 cents.

Do you happen to know what horsepower you get with the mppk tune from bm3. I currently use it and it changed my sport displays to 400 and it peaks near 330-340 hp. If there's no difference between the mppk and stage one. I wonder why they don't up the boost in stage 1.
