nice job!!!

more fotos of the car, please :shrug:!!!

thats the perfect alternative for the 5Zigen fireball mega exhaust...which i want badly.

looks good to me

dude, good job

Nice JZX81 Mark II!

lets hear some sounds clips...

Nice work! Looks good. Any side shots?

thanks for all the response,

as for sound , when your own it it sounds like Nascar. cruise is pretty mellow and deep.

side shot request

what kind of welder did you use?
 
the sound tone is really good.
i like :)

yes i love it.... i welded up 2 flowmaster my q45. sounds ok... thinking of redoing the whole thing to a single muffler, dual in/out to make it louder....

nice

that looks amazing! well done for having a go at it urself, and making it work! i want one bad!

sounds so nice, my cousin is gonna drool when I show him this, he's been wanting the 5zigen mega for his LS400

i like, what size piping did you use?  2.25 is optimal for a stock 1uz motor.

Im using 63.5 mm pipe, how did you figure optimum piping size for the 1uz?

Nice job!!! Good skills!!

looks good... car and exhaust. :biggthumpup:

search on lextreme and clublexus, a variety of tests have shown that ~2.25-2.5inches MAX (for the 2uz/3uz) is the optimal cross between exhaust flow and exhaust velocity.  too big and the velocity decreases greatly, causing a loss of low-end torque.

with 2.5in on an early 1uz you will probably feel some loss of low-end torque, especially in comparison to a 2.25in setup.

 Actually, when i did the exhaust i experienced some power loss in the midrange. From a start "leaving from a light" the car gained tons of response and power. a few days later i put a drop in K&N filter and used a whole saw on the airbox and opened up some breathing and it made a world of difference no mid range loss and screams all the way to red line. I had searched and found no real test just internet say so.  

 Im thinking the X pipe design is a winner in my situation. Also think about this, they sell 2.5 exhaust to mustangs and most of them make less power than the 1uz. what size do you run and what are your results?

And thanks to all for the nice comments:biggthumpup:

i run 2.25" piping, cats back w/x-pipe.  noticeably bettter low/middle end, top end seems slightly better, though its not as noticeable.

MUSTANGS run 2.5" piping because most of them are either 5.0L or 4.6L motors....

Looks great buddy! And sounds awesome! I think you have done a fantastic job! Congrats on doing it all yourself.

I like :biggthumpup:

wow im loving this build right now!!!

looks and sounds great man!

nice way to make mufflers wered u go for the tips n muffler??
