N/A setup

[thebarber]

2.5" intake is too big, won't work with the MAF

forget the axleback and get a custom-made exhaust from the resonator back. the cats and resonator are 2" thru and the exhaust shrinks to 1.75" after the resonator. i had mine replaced last week....its worth the effort. skip the high flow cat, not worth the time/effort.

get a dc header because all the other headers are junk

nst underdrive crank pulley and lightweight water pump and alternator

1zz throttle body is ok

1zz injectors not likely req'd for n/a setup

wait for cali_yaris's intake manifold

get lightweight 15" rims, skip the 16's

Tanks, but for de 2.5 intake, I have buy a fiting for this. I ajust the diameter for the MAF!

For the cat hi flow, this is because I got one at the past and it is in my room!

tanks for your help!

Haha i didn't realise the piping for the cat and resonator were 2" already. Only remembered the exhaust place saying that the piping that they cut off from mid to muffler was 1.75". Guess that's good that i got 2" piping down then.

Hehe learnt some new info.

About 3 or 4 weeks ago, I tried to do a DIY axleback and failed miserable, because I read many times on the forum that our stock axleback exhaust pipe diameter was 1.75", but it's actually smaller than that. I measured a 1 3/8" ID for the piping just before it enters the muffler. I have an '08 Yaris 'S', but It should not be different than any other Yaris hatchback.

cali_yaris is doing an intake manifold???? where are the updates for this?

Barber what do you think about getting a custom exhaust done from the catback instead of the resonator back? Why did you recommend to the OP that he start after the resonator?

Is there any other exhaust piping that needs to be increased to 2" besides the resonator-to-muffler piping?

Also if you're running an axleback already would it be easy to go to a muffler shop and have them convert from an axleback to a catback?

the cat and resonator are right after one another....and it may have been lost in the hack, but when magnaflow was fitting their system to the yaris, they said the cat and res were both 2" thru...so no real need to remove the resonator unless you want a louder exhaust

i paid $200cash for my 2.25" crush-bent exhaust piece from the res to the axle section...

Did you have them attach the custom pipe to an axleback you already had installed? Is that possible?

So the piping is the right size after the res but is there another piece that needs to be increased? Maybe the up pipe or the down pipe?
