So anyone running Labrees...can you say yay or nay on this idea?
Being the "seperators" you have to run for the K03 or K04 turbos were starting to deteriorate in mine and I was switching back to K03's(on the Avant)for the time being I had to remove them. However the bolts were shot..so I had to drill all 4 out. Well, then the studs that were left could not be removed, so I had to drill out ALL 4 holes in the DP. Do you think there will be an issue running a longer bolt thru the seperator and the dp then running a lock nut on the longer bolt on the outside of the DP? Or do you think over time that nut will back out and the nut will go into the exhaust leaving the seperator in there loose? Just curious as this is pretty much my ONLY option or get new DP's. And to be honest...I'd say until Labree makes those in stainless...I'd run Autospeed. Not to mention I haven't really got ANY true feedback or help from Labree or the two retailers I got them from. Figures....forum can't always be peachy for retailers can it?

No, because the seperators don't give you the leisure of running a bigger bolt

I guess a cotter pin is possible, but trying to locate the right size bolt with a hole in it can be a challenge..and drilling it???? That would be fun! HAHA...good ideas tho, thx

seems like it should be ok w/ serrated washer, lock nut, locktite and some
wads of gum.
i thought Tantrum said they would help?

Labrees, great idea, but does it work? go ASP! (long theory)
I'm a Physicists so I may be going to deep but....
So you have separate paths for the wastage & turbo.
This is suppose to speed up the exhaust & cut the exhaust wave.
Thus moving the exhaust gas faster.
I do believe it does that. Pulse wave tuning is so important!
Now, here is where I think they fail....
Look at the openings, there both small, in fact smaller then stock.
Yes, they do open up, but until then, it is a bottle neck. This will slow down the exhaust, & chamber the pulse wave. This will generate a TON more heat right at the turbo. That's BAD for performance & turbo's.
Then when the WG shoots down the other tube, it will create a negative pulse wave on the turbo side. When the turbo has to respool it will not have the slight vacuum of a normal DP. The WG dumps exhaust at a faster rate then the turbo. This changes the exhaust pulse & speed. Giving a little more lag.
What I do think labree pipes try do, is try and speed up the pulse wave from the turbo, this should spin them up faster, but will max out on flow (generating heat)
I'd have to do a lot of math & measurements & get the exhaust pulse (harder on a 2 valve exhaust) then do flow charts.
IMHO, they are not worth it if you want top end power, there a mid range DP. Long term life of the turbo may suffer due to heat build up at the turbo.

They did...and they are "supposedly" shipping two new K04 seperators out, but
that doesn't solve the holes in the actual DP's. I think a serrated washer and lock nut will be fine.
