GTR on the way
We discussed both cars. By the time we were done, I was sold on the GT-R.
Great addition. Very curious to hear your feedback on the car compared to the p-cars you have owned. Ive also considered picking one up to compliment the 996. Either that or a ZR1/GEN-4 Viper, but I'm leaning towards the GT-R.
Scott -
Congrats! I figured you pulled the trigger after our conversation and the advice you have received from other members.
I've thought of getting one as a daily driver since I could drive it all year.

Regarding our conversation: I went through my old dynos... This one is a custom tune on a stock car.

I don't have a dyno sheet with my new tune (now that I have my Y-pipe), I plan on getting one withing the next 30 days.
Also, per the discussion: The factory exhaust is 76mm. Right out of the turbos, I believe it is 76mm. It goes into 76mm downpipes, into a 76mm dual Y-pipe, which feeds into 76mm outlet, into a 76mm mainpipe/rear section.
I believe your boost logic pipe may have 75mm inlets leading to a 90mm outlet. These are the dimensions I wanted in my Y-pipe, because the 90mm rear sections net some of the better gains over the 80mm exhausts (Amuse, etc..., but there are a few that are larger). So right now you still have the two bottlenecks - downpipes (AMS has 90mm downpipes, and I think AAM and few others also offer some nice ones), and rear sections (90mm Y-pipe into the factory 76mm main pipe/rear section).
Once they open up, combined with a custom tune with the Cobb AP (which can be tuned by any of the tuners mentioned (including Switzer), you should have an extremely daily drivable 650hp GT-R, that can also do 10's at about 128-131mph. The newest thing to help GT-R's run the 1/4 is newer (V2) intakes with larger MAF sensors (to use more of the air for calculations). This may also require you to get bigger injectors as well. When it is said and done, with a few bolt-ons (bigger turbos, intercooler, etc...) and about $10k later - 650whp, in a very stable DD platform is doable on the stock transmission.
After reading this post, I realize it may be too much information (especially because you only mentioned exhaust mods, and possibly a tune). But I figured, I'd just throw it out there, and whatever lands - lands.
