Yaris Exhaust Center Section - Toyota Yaris Forums

cdydjded · 03-03-2010, 05:26 PM

I can have made locally the center section of the Yaris in the following way:

2" or 2.5" diameter pipe
With 1 or 2 200 cell catalytics (factory is 600 cell)
mandrel bent
Aluminized or Stainless steel
Bolts on to the factory header or aftermarket header
02 Bungs
Hangers

Also if interested I can have a rear section made with almost any muffler. My question is are you interested? Estimated cost for the center section would be around $275-$375.

I voted for the 2.5 center section, but I may also be interested in the rear section if the price is not too high.

Looking forward to the updates!

I am assuming when you say center section, its the mid-pipe?

i think a 2.25" exhaust from the header back would be the best...2.5" is likely too big unless you're running a turbo or s/c and the stock midpipe is 2" from the header to the rear end of the resonator....its only 1.75" from the back of the resonator to the back of the car...

I agree with you on the 2.25". Ill check to see if the can make that size also. 2.5" is a more common size & they always have the machine setup for it.

2.5 inch is waay too big IMO unless you're boosted. 2" mandrel bent would be perfect for NA applications.

This what I measured from my stock exhaust:
Out of the header 2" and widens to 2.25
2.5" in/out 1st cat
2.25" between 1st & 2nd cat
2.5 in/out 2nd cat
2.5 in/out resonator
1.75" from resonator all the way to the muffler

So I think also 2.25" would be best

Yeah I'm also thinking 2.25 would be best for me, since I'm not planning on boosting the car anytime soon. OTOH I am planning on adding nitrous and will be installing my WR header at the same time... So I'm also considering a 2.5 diameter for now.

magnaflow measured it waaaay back when.....they said (implied?) stock piping from the resonator forward was 2" I.D. (inside diameter)
