I bought the headers a year ago straight from Kooks. As far as exhaust, I may just get a set of race mufflers and dump them after the collectors, or look into Kooks 3.5"x 4" Ypipe, 4"" race muffler and dump them before the rear axles, we'll see.
Kooks doesn't show anything on their website that fits those headers, only 3 inch collectors.
Yeah I'm not seeing it on Maryland speeds website either anymore. But they have either quit making it or just have to call and ask, because I know it exist. I have one on my car right now lol.

How do you think it compares to their true duals? Sound and horsepower.

IMO, I like the y-pipe for a cleaner and more simple install. Not to mention it should weigh a lot less. Personally I don't think I would pick up anything going from my setup to a full true duals all the way out the back. That's just a lot of extra tubing.

blk00ss, you run their 3.5"x4" ypipe? Do you have any vid of the exhaust set up? It would be nice to hear em. Thanks

Here's a first start up clip. Untuned and just open y pipe. And yes it's what I run. I have the 2" long tubes with 3.5" collectors to the kooks 3.5"-4" stainless y pipe to a 4" mufflex catback and with a borla xr1 oval muffler. Oh and a manual 4" cutout.
Thats sounds mean and wicked man! And a NICE looking car as well. Thanks for posting it up. On another note, any clearance issue with the Kooks 2" headers that I should expect? Again thanks.

Thanks man! She's my baby. The 2" kooks fit a ton better than a set of 1 7/8" ARH. I have a regular BMR k member so they fit awesome. I had a set of 1 7/8"-2" kooks a few years back. Had them on the car with the stock k member. Only clearance issue I had was the pinch weld on the k member was rubbing one of the primaries on the passenger side. Just hit it with a grinder and ground it down a good bit. Fit good after that.

Thanks, and good to know. I will be running the same Kooks 2" headers with 3.5" collectors. I have a Spohn K member with manual rack, so hopefully it will clear with no issues, as well as the Moroso oil pan. I should be getting close to this install shortly. Thanks.

You won't have any issues. You'll be amazed at how well the fit, I bet. I'm ready to see some results of your build. I've been following it a while.
Found time to mock up the SPOHN K member/manual rack. I'm amazed with so much clearance to the MOROSO oil pan. Also, utilizing UMI solid motor mounts. MEZIERE EWP installed.
Little progress update here: Installed MAST heads today with ARP 234-4317 head studs, Cometic gaskets-4.130"x.045", Morel 5425 SR lifters. Also mocked up the Kook's 2" headers and MAST intake manifold
Wow, this MAST LS7 head and Morel 5425 lifter combo is going to require some long *** pushrods. I used a Comp pushrod checker that I previously used on my LT1, and practically bent it due to full extension. So I have to order a new set of checker, which I just did just now. It looks like its going to be in the 8.800"-8.900" or so length. That's a big difference from stock length 7.400".
What are you doing with the DOD holes? Most guys i've talked to suggested tapping those holes with a 1/8-27 npt tap (rather then relaying on the orings in the valley cover) to be sure they are and stay completely sealed.
I just turned my block upside down on the engine stand and drilled them out with a 11/32 drill and tapped them.No worries about getting metal shavings in the block this way.
