Midpipe/cat back exhaust for sedan

[1.5]

So ive looked around and can only find the nitto midpipe for the Yaris but it only fits the LB. Is there a midpipe out there that will fit the sedan? If not are there any cat-back exhaust systems available for the Yaris at all?

[thebarber]

magnaflow makes a catback for the yaris sedan only...

otherwise, go custom

[1.5]

a custom midpipe would way out perform a magnaflow cat-back im sure. Im just gonna go straight piping from the header back lol look out popo lol. Holy Shit and i just looked up the magnaflow system and its $724!!! Dude its a Yaris!

[thebarber]

i picked up a used megan axle-back and got a custom 2.25" crush-bent midpipe made for $200 cash....cat and resonator are 2" thru....and much bigger than 2 or 2.25" on a 1.5L you're going to lose your bottom end...

[1.5]

thats a nice set up. I live in florida so i have no problem with removing the cat altogether. But yea on a n/a 1.5 i wouldnt go larger then 2.25

[YarisSedan]

For any car its usually cost effective to go custom. Just pick out a universal muffler you like and have muffler shop do all the piping and welding for you.

I live in Florida also.. not cat no problem. I was looking to do from the header all the way back to my TRD axleback. Are there any sensors that i need to worry about or any CEL that might come up if i do this?

[1.5]

Yea ur gonna need a defouler for the 02 sensors. Im sure there are 2 of them so u would need 2 defoulers or u will throw a CEL (not sure of the code tho)

Just take it to an exhaust shop so you can get some good mandrel bent pipe. Shoudln't cost more than about 4-500 for a headerback with muffler. Only issue will be finding a shop to do a job without cats.

[1.5]

Check your states laws and regulations and emissions laws and DO NOT forget the decibal laws cuz a catless exhaust will surely attract the wrong attention and if you live in a state with strict laws even on sound, they will ticket you or something of the sort. If catless is legal then you should be able to find plenty of shops who will do it.

where i live in the country they could care less.

Gainesville? thats a huge college town cops suck there!

[Yoda]

they focus on DUIs and speeding more than noise....

[cali yaris]

please do mandrel-bent.

[Yoda]

sadly no1 in Gville does that

[PHXDEMON]

please do mandrel-bent.

This. Crush bent is crap.

[thebarber]

crush bend is certainly a cheaper way to go....i have a 2.25" crush bent section from my resonator to my axleback section.

if i was more patient, id have ordered in some mandrel bent pieces and got it welded up, but i wanted the exhaust before i dyno'd....so i went w/ a larger diameter than i wanted with the hope that the crushed sections would still be 2" diameter

still pulled 106whp/107wtq with intake and my partially crush-bent exhaust....

[Yoda]

hey thats some really good numbers. I pull close to 112whp with I/H/AxleBack/Pulley/TB. I just now uninstalled the TB after 3k miles. It made the car jerky and a pain to drive. So i sit at 108whp now.

[1.5]

thats not bad but ive got time so im gonna look around and try and find a shop that will do mandrel bent piping. I live in tampa and there are plenty of shops around here so I should be able to find someone.

[Yoda]

sigh lucky you....

[1.5]

come to tampa man its like a 2.5 hr trip at the most and u can get some exhaust work done lol in the yaris its maybe a half tank lol

[Yoda]

you get me a price and i will google map myself there

[1.5]

alright sounds straight when I get my quote I'll let you know

[Yoda]

i was reading up on it. From what I read we might lose some low end tq if we do the the header back.

[1.5]

well if you go with piping too large for a really small engine like we have and no forced induction then yes you could lose a lot of low end. But if you keep the piping at like 2in or so then you should be able to keep the low end power we do have while giving us a lot of top end due to the free flow of exhaust gases.
