LS6 intake with EGR ... What are the different designs? I've seent the SLP version ... the one that is prone to leak around the EGR fitting.
What is different with taht design and the LS1Speed version?
Are there others?

Re: LS6 intake with EGR ... What are the different designs? I'm not familiar with the LS1Speed version, but I remember ARE also modifying the LS6 intakes. There's also the LPE adapter. I know that the LPE mod doesn't use the leak-prone O-ring seal that SLP uses and you can do it yourself.
Here's the link, but I noticed that they've jacked the price up to $108 now <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

Re: LS6 intake with EGR ... What are the different designs? I bought a factory GM LS6 intake. I then bought the Lingenfelter EGR adaptor.
I drilled out the intake with a 1.25" hole saw drill bit. I then took a file, and smoothed out the hole, washed it, then blew it out with my compressor.
I then prepared both surfaces of the EGR adaptor and the socket that the adaptor slides into on the intake with my dremel and a sanding drum on it by roughing up the surfaces a little and once again blowing it out with my compressor.
I then got out the JB Weld indrustio weld, mixed my gooey concoction and spread liberally on both the surfaces of the EGR adaptor and the walls of the socket on the intake where it slides into.
I then proceeded to pound it in (as it did fit snug already) with the butt of a screwdriver until it was perfectly sealed against the base of the intake where it sits on. I then let it dry, harden, and seal for two days with the first 4-5 hours under my hot halogen light.
When I reconnected the EGR on the car itself, I still used the rubber o-ring. It was tough to tighten down but that friggin intake will snap or crack itself before that seal is broken or that adaptor comes out. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: LS6 intake with EGR ... What are the different designs? Yes, that's exactly what I did. I bought my LS6 intake long before SLP and LS1 Motorsports came out with their modified versions. So instead of wasting more money on another, I just modified mine to work.

Also, here in Illinois they just recently changed the emissions test for OBDII vehicles. Instead of doing the IM240 roller test, they now plug into your data port under the dash, scan for DTC's and check that all operating parameters in your PCM are still active. Turning off the EGR in the PCM if subjected to this test, could raise a red flag.

Re: LS6 intake with EGR ... What are the different designs? That may be the case. But drive a 98, 99, or 00 that someone like myself has plumbed the EGR system into the LS6 intake and then drive an 01 or 02 with an LS6 intake and no EGR and tell me which one is the smoother of the two in light to mid throttle applications.
I wasn't saying that the non EGR LS6 wasn't smooth, just that when the EGR is doing it's job makes it an even smoother transition.
As an FYI, I had Ed Wrong do my original PCM tuning. On the third attempt he turned off my EGR even though I told him I DIDN'T have an LS6 intake installed yet. Needless to say, with the EGR turned off, it ran like sh*t and I suffered a sh*tload of KR at throttle tip on because of it.

While it doesn't appear to hinder performance, it will red flag an emissions test.

Re: LS6 intake with EGR ... What are the different designs? GM designed the cam differently with the LS6 intake in those years to eliminate the need for EGR. Us 98-00 guys need a different cam to accomodate the LS6 intake without EGR.
On another note, what intake, LS1 or LS6 any year, came with 2 bolts for the EGR? I've been asking for a while, no one knows
