can anyone chime in on whether or not headers provided an added benefit to this setup...
im guessin not due to it working better with stock cats..

Long tube headers if you can. Stock cats aren't worth keeping, since they'll blow.

I haven't heard that, in fact Stillen insisted that I stay with stock cats to achieve max power. I had to ditch my art pipes to do this. I'm pretty sure that headers are OK, but the power gains are so minimal over stock manifolds (14hp) I doubt that it is worth the trouble as they are are PITA to install. You will also have the additional back pressure of the stock cats so not sure how much you might actually gain.

The added heat to the system will prematurely blow your cats. I've personally had this happen to me as well as many others here.

You will lose some boost from moving over to test pipes and/or headers due to the change in scavenging (not back pressure). I went over to test pipes because I didn't want to keep putting out money for cats and HFC's don't last nearly as long as oem. I've seen people make great power on test pipes though, so I don't see it as a big deal. You can always put the 9psi pulley on as well to compensate for the loss boost.

Thanks for this information milkcow. I posted here and asked members before I removed my test pipes and no one said anything, in fact I had one member say he tested with and without, and power was was gain was significant on a dyno. How do I know if my cats are burning out? and wat is the down side of running with burned out cats?

I know there was one person who did dyno runs with and without cats, but the significant power loss is most likely due to a tuning issue.

You'll know when your cats blow out. The cats will start making a rattling noise when they are about to die. Your car will run sluggish and CEL will eventually come on.

I doubt of my CEL would come on as I have no O2 sensors in the cats.One position is used for my AFR gauge and the other is disconnected. Tuning bypasses the required input from the sensors. I have noticed that my car is a bit louder this summer so perhaps they are burning out. I don't know why Stillen is so **** about having the OEM cats in place. Ok... so on the question of back pressure vs scavenging... I thought that scavenging was a term used more for turbo applications as simply put, scavenging is the extraction of exhaust gasses from the engine's cylinders... and those exhaust gasses are then used to fuel the turbo?

Guys question. Please help.
Besides oil cooler, upgraded fuel pump, colder plugs and custum program, what else is recommended to be used or replace in preparation for the stillen supercharger? What's a fair price to pay for an instalation of it and the tune. I have a used kit and I'm ready for the installation soon.
Who you recommend in the tri-state area?
Nj, NY etc..

You can check out Real Auto Dynamics in Oceanside, NY. They are very familiar with installing the kit. Expect to pay around $1500. Besides everything you get in the kit, you only really need the oil/trans coolers. I suggest getting the frozenboost cooler as well if you intend on staying W-A.

I would never do the oil cooler again. It is a huge PITA to use non standard oil filters and Stillen recommends a Fram if you can believe that. It is rare configuration because it needs a wider gasket diameter. I do not track my car so I see no need for it. I would definitely go with the FB intercooler upgrade. The Stillen one is pretty lame and you will have heat soak issues. The colder plug... well you should read my other rant on that. Get new plugs for sure, but the heat range of the Denso FX24HR11 (stock G37) is the same as a GT-R plug. You just need to regap it to .028-.031. I got a custom gauge pod built by a guy in Toronto... it looks great - PM me if you want his coordinates. i went with Innovate AFR and Boost gauges. If you are 6MT you will need a new clutch. I went with the Southbend stage 3. Your car will feel pretty soft with all that extra power. I found that Hotchkiss sways helped a lot. Oh... and you will have traction issues Look for wheels that will accommodate 285s

Got the oil cooler install already , also stage 3 cluch complete kit from South Bend, stillen Headers berk high flow cats ark exhaust, coilovers with Hotckings sways, rolling on 20" vossen, I also have the frozen zone upgraded cooler, hks colder plugs, walbro in tank pump, upgraded pulley, injectors, and compressor wheel on the supercharger. I'm in missing anything? Ohh I have the uprev computer cable and license from Diego from vossen too.
Call that shop in NY you mentioned. Is $1500 for the installation plus $700 for the tune....

Dump UPREV and get ECUTEK, you'll need a tune that doesnt use the MAF's. with all those upgrades and not tuning with SD(Speed Density) your asking for trouble, the MAF's on the Stillen kit are before the SC( Wrong spot) or look into going Air-Air there is kit that TOPGUN makes, it's over on The370Z forum.

+1 on EcuTek. Also, you'll want to get rid of the cats, especially high flow cats, as they'll blow out quicker than stock cats. Go with test pipes. I'm not installing my SC until I have the air to air kit. If you're running a bigger pulley and/or upgraded impeller, you're really going to be risking your engine.
