Wtf Did I do to my sho? New exhaust makes my car sound like a rice burner

White smoke that smells of oil normal?

Today I started my car, it was idle for about a minute and white smoke that smelled like oil came out the exhaust -- it was just a puff then it was gone...

Is this normal?

I never had so many problems after a mod -- since I got his damn exhaust + downpipes.
 
Lot of guys with catless downpipes complain about white smoke.  Some say it's failing turbo seals, some say it's due to lack of back pressure.

 
I literally just PM'd ajp asking about lack of back pressure.... I'm leaning towards ditching the downpipes. I'm really not happy with #1 the new sputter #2 the white smoke #3 the rasp.

I'm ragin' at the moment lol'
 
Most guys who complain about the white smoke are the ones who do catless DPs AND install the Corsa (it removes the 3rd cat).  Guys with catless DPs and stock exhaust still have that 3rd rear cat to clean up the smoke.  As others said, the white smoke is there on all the SHOs, just the cats clean it up.
 
At first I thought you were kind of being a bitch, but it does sound ricier than I expected.  Almost feel like I should go with turbos and downpipes w stock cat back to keep it sleeper.  I have a Civic with can exhaust in the garage, if I want everyone to stare at me when I drive by. (which coincidentally might sound better than your car does)

LOL

Such a gentle way with words you have.
 
It has to be a back pressure issue.  No way seals are bad on every catless DP w/ 3rd cat delete SHO.  That's the common theme. 

I believe the MazdaSpeed3 guys dealt with the same issue.
 
There is a big misconception going on about turbos needing back pressure for the seals to hold the oil back...it sounds good but it's just not that way

I have 2 other cars with turbos and none have cats ....even had a wrx with no cats and none smoked...these are cheap journal bearing turbos...Tasca has them for 395 each..that's about the cheapest turbos I've ever seen..

It's very easy and common to over feed the turbos with oil...often u need to run an oil restrictor but the turbo mfg and oems will never recommend that in fear of starving the turbo of oil.

Most turbo oil seal today are metal and there is really nothing to go bad

I'd be curious to see the range of oil pressure these engines operate at...chances are it's over 50 psi at times...if that's true then running a -4 oil feed with no restrictor will blow oil past the seals....my coyote mustang makes over 80 psi and needs restrictors for the turbos and my civic makes over 90 psi and needed restrictors for the turbo ...I switched to ball bearing turbos and no problems
 
With my engine issues and possibly weird Wisconsin gas, I'm going to load the 91 octane tune to see how it fairs on my car. I'm going to verify its a 3 bar tune...
 
Usually the best way to determine proper oil feed to a turbo is to measure at the drain..I forget off hand but hellion told me it should be something like 15-30 ml per 30 seconds but I'd have to call them...that's how they come up with whether or not to use restrictors and what size...almost all ball bearing turbo comes with built in restrictors.

You can call around but turbo mfg will almost never reccomemd restrictors for journal bearing turbo

I believe these turbos are over fed and the cats mask the problem and some that don't have any cats and no smoke may be lucky...and there really aren't that many people with shos that are catless with 3rd cat delete...there are some but most have catted down pipes

Most turbo companies will point to your pcv system or a drain problem if you are smoking...but we have ken designed pcv and drains so I doubt that's the problem.

And it's hard for me to believe that ford designed the oil feed wrong so I'm really torn on why mine smoked when I was totally catless
 
You really need datalogs ....I'd look at them but I'm not sure if you  log with mycal if I can open it with live link but if it's a csv file I may be able to open it with live link not sure tho I've never tried maybe someone else know..

 
:)
Comes across a lot more harsh than I really intended.  On the Honda forum I used to be on, I once heard someone describe me as "an ass online but pretty cool if you meet him."
 
I apologize for intefering,but this is reference to the OP.was curious to know if you used new gaskets x4,or if you re-use the old ones it will leak causing o2 sensors to read incorrectly causing fluctuations on your AFR. Z

Is the sputtering still in the same speed/gear area or has the issue spread?

The sputtering was between 2-3 and when I put it to 91 octane it turned to 1-2 and 3-4. It also was at a different speed... and it wasn't at WOT either. When I said it got worse... it got worse. I literally pulled over on the side of the road, shut her down and put 93 back in fear I was going to EFF something up.

We all give each other a hard time here... Consider yourself one of the EPF's....

Weird this sounds familiar. Wondering if this is becoming a trend.
When did you have this problem? Recently? I do you have the thread and did you get a fix? Are you torrie now?

The Stainless Works catless DPs were either Copper ATV'd or the original gaskets were put back on ... I don't remember --

I am going to Late Model Throttle to see if I can get a data log done on the car to figure out WTF is going on with the sputter. Also I need a bit of peace of mind that nothing is majorly JACKED. They specialize in turbo charged cars and have some pretty beefy setups...

If I can get the logs I'll forward them over.

on a Side note --- THANK YOU to everyone who's commented on this... there is such a wealth of knowledge here an I appreciate it.
 
Here is the link, I was having a sputter/hesitation. Nope still with LMS.
