Header + Mid-Pipe + Exhaust Installed - Toyota Yaris Forums

WR 4-2-1 Header
Nitto Mid-Pipe
Greddy Ti-C axleback Exhaust

the header & mid-pipe is quite quiet, just like the stock one, I can't head any sound from them inside the car...I only can hear the intake & exhaust right now

now the car runs pretty smooth without 2 CATs...but the gas smelt very very bad tho

about the exhaust, really quiet when you compare the HUGE tip with the sound

Idel: same as stock (inside the car), low deep tone(outside the car)
under 3500rpm: still pretty quiet(inside the car)
over 3500rpm: started to become loud

forgot to took a picture at the rear...

------------

p.s. any know how to bypass the O2 sensor in the mid-pipe? I'm still working on it

Alain, I think you deserve an award for the most quickly upgraded Yaris here

For the O2 sensor in the midpipe, the common fix is to use a spacer (aka spark plug anti-fouler) or an elbow joint, Garm's got some of those available too, I believe.

BTW the exhaust smell is worst when the car has just been turned on and is in warmup mode (rich mixture) but it's not to bad once it's been running for a while.

Him,

you need to post a soundclips please

CDavis7M · 06-27-2009, 12:31 PM

It looks like the midpipe and maybe the axle-back are the same diameter piping as stock. Is that true?

blacksandiegovitz · 06-27-2009, 01:16 PM

Nice bro ! I'm running similar set-up and yes it does smell pretty rich sometimes ,but hey gotta pay to play right lol.

It's only a lil bit bigger, but less restrictive overall

*tk-421* · 06-27-2009, 01:49 PM

Looking good! What's the piping diameter? How does it perform? TIA

Um...the diameter of header is a way bigger than the stock one(front & end), the front of the midpipe is almost 2", but the end is less than 1 3/4, the axle-back is the same as the end of the mid-pipe. so may be that's why doesn't sound too loud~

thebarber · 06-27-2009, 02:12 PM

wow, that is a CLEAN yaris....i dont know that mine was even that clean when i drove it off the lot

nice job on the upgrades though!

PETERPOOP · 06-27-2009, 02:51 PM

no messing around when coming to modding the yaris. that's what i like to see!

Split · 06-27-2009, 05:13 PM

what's the quietest aftermarket axle back available for the yaris hatchback? is it the TRD? Or is there some Vitz one people can order? I bet that would sound incredible with this set-up.

Also, keep your factory mid-pipe because eventually the first resonator in your nitto mid-pipe will fail on you and start rattling. it cant handle the heat coming from the exhaust.. it ends up burning the packing material around it. At that point i'd probably just cut it out and weld in the factory catalytic converter there. If i was doing it all over again, that's what i'd do anyway.

Split · 06-27-2009, 05:15 PM

Also i can't help but noticing your nitto mid pipe looks different than mine... on mine there is a resonator RIGHT after the o2 sensor which caused the car to idle rough. Looks like its been removed. I had mine cut out and it fixed my problem. looks like nitto figured this out and removed it.

Maybe the TRD or Apexi WS II, if your looking for quiet. The Apexi WS is known for being very quiet.

1NZYaris1 · 06-28-2009, 04:21 AM

Wow , not only the fastest Upgraded Yaris award , but i would have too say the cleanest ,

, has it even touched the tarmac yet

Super clean and super hot

Kaotic Lazagna · 06-28-2009, 05:24 AM

Man, my friend just has the Ti-C axle-back, and it's pretty loud already. I guess I'll hear yours at the meet. hehehe.

I think mostly because the Ti-C for yaris can't remove the silencer....or may be I don't know how to take it off...it seems the silencer is welded to the tip itself.....
