1jzgte into FC build thread!!!!!!!
I wrapped the ypipe and the complete downpipe today.
WOW, much lower temps under the hood, better response and more power.
It also quieted it down a lot. I guess I really was hearing the exhaust noise through the thin metal pipes.
I can't even feel it pulling timing anymore, intake air temps must be way down.
I highly recommend wrapping it!
On a side note, breaking in the wrap was fun. Smoke everywhere at a few stoplights, people looking really confused :P

for the y pipe and the entire down pipe it took about 70-80 feet of 2 inch wrap! expensive but worth it IMO
I'll be re dynoing once i finish the rest of the exhaust. still have the stupid restrictive stock rx7 exhaust.
I'm going to make a custom catback from scratch for under $100.
Going to run 3 inch pipes for the exhaust (dual) and open up the stock mufflers and mod them to flow better.
It will look stock, but be FAR from it

NEW VIDEO:

hard to tell by the video but it's loads faster than it was in the last video. Speedo lags like crazy.
I finished a 3 inch cat back with the modded stock mufflers. It's still very quiet...
guessing about 250-270whp with this set up

Dynoed again today.
Exhaust mods alone it made 250-260whp, 266 ftlbs!
Thats up about 25-30 from stock exhaust
Then I turned up the boost a little
13.5 psi peak dropping to 11 by redline = 268whp
14.5 is peal dropping to 12.5 by redline = 280-285 whp, 277ftlbs
Car is starting to haul *** now
Might switch to a better cat back, I know it's holding the power back. It's still very quiet actually.
Overall very happy.

about the powersteer
I have 2 threaded lines coming from my rx7 steering rack,
but the 2jz p/s pump only has a spot for one outlet the main pressure source?
so what did you do with the small threaded hose when you got your hoses made up?
cheers daniel
