Thoughts on smoke (vids included).
Ever since I had the OS Giken installed along with z1 2.5" Test-Pipes I have had what I consider excess smoke out of the exhaust. At first I thought it was just the new test-pipes causing the smoke, but it seems to be continuing.
Before: Sorry only vid I have. Very little smoke if any. This was with kintetix Test-Pipes.

After: Current Mods. As you can see it is considerable.
I guess I am a little worried. The car seems to be every bit as strong as before (actually quicker due to losing 23 pounds of excess weight taken off the drivetrain). The car burns 1/2-3/4 qt. of oil per 3000, which is the same as it has since I bought it. I am pretty hard on the car, but only put ~200 miles a week at most on it.
Thoughts?

If it's not burning any more oil than before, I wouldn't sweat it. Is there anything different with the internals of the two brands of test pipes? You've also added a tune since the two vids, no? Maybe running richer than pre-tune?

Same tune.....all I swapped was the test-pipes. They are either 1/4-1/2 inch ID bigger than the old ones. I guess it could still be the coating that they put on them initially. I have only driven ~1k miles since the install. It smells of fuel no doubt about it, but at times it smells a bit of oil too. I just wasn't sure so I thought I would look for some input.

Black is pretty much fuel / air mixture.
blue smoke is primarily from internal engine wear ( Edit: Not 100% sure about this tho) .

I think this weekend I am going to take the intake, plenum and such apart and see if I am perhaps getting some blow-by creating the smoke. I have been meaning to take the grinder and smooth off the castings on the upper and lower plenum anyway. Now I just have a better excuse to get a burst of motivation.

I am not porting anything......just cleaning up the casting flaws that are there from the factory. I don't think it will make any difference in the tune. Obviously the car is pretty rich all of thus sudden.........when the weather cools I might take it in for a "check up" tune.
