I am such a stickler for quiet, though, I am removing my GTM system and installing the ARK Grip system. The GTM system performs wonderfully, but my wife wants it even quieter.

That's a consideration in MY household.

lol. Yeah coop. Dual 2.5" has an area of 4.91'' per pipe for a total of 9.82".
A 5" exhaust would have an area of 19.63".. so yeah 2x2.5" is not equal to 5'' in this case.

Following blindly, 2x2.5 has about the area of a 3.5 inch pipe. Of course, it's not just about area, but we will save that for another lecture.

Agreed. Point is, for OPs desired power level, 2.5 is more than enough. I would use the money on something else.

+1. A 2.5" exhaust will be fine. The HKS exhaust is actually smaller at 2.36".

Thank you. Open mouth, insert foot.

Whatever it flows, it's seems to be enough.

And I will second what others have said about the oil cooler. Go with the 34 row with the thermostatic plate. My oil temps never go above 220 and on a cool day are right around 190-200.

I will definitely be getting an oil cooler now. I guess the parts that I read where a little wrong. So thanks for this info. I am also glad to hear that you have a berk exhaust with a TT and glad to hear that you like the power that you got with it. Out of all the exhaust I enjoy the Berk sound the best. So this news makes me happy

Here's the clutch I'm referring to

90-96 300zx Twin Turbo South Bend TZR Clutch Kit

I am from south Cali, I live in the San Diego area. And thanks for looking up that clutch for me. I want to get a really good clutch but not to expensive. But when you go FI cheap really isnt a word used I have come to find out.

With that said, if I was ever in proximity of a cop, I short-shifted every gear and did my best to stay out of boost.

Thanks Nixlimited, this is the kind of thing I was hoping to hear from people about. I was hoping that even if I did have BOV that as a long as I didn't act a fool as you said, I should be fine.

I am going out to sea for a month in a few weeks and when I do I am dropping off my car to have my TT installed. Ill keep you guy up dated with the results when its done. Thanks for all the feed back so fare
