Depends on hp. Are you still running that "garret rated at 700hp" turbo? If so, that works out to 595rwhp through a 6pd, right? Reminder: for high boost always run the correct octane of fuel. If those are the correct numbers, then really any 3" or bigger exhaust system will work. Note: This has to be 3" or bigger all the way through, with mandrel bends...including the downpipe and the midpipe.

You really only need to go to a 4" exhaust system at >1000whp. Some guys that run >1500whp with the 2jz-gte (usually trailered race cars) will even use 5" piping.

From a big-picture perspective in the world of the 2jz-gte, 595rwhp isn't that much. No need to go crazy with the size or price of the exhaust system.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
