2ZR Turbo Yaris

New exhaust solution

Rather than going through the hassle and expense of finding another rear mount muffler and paying an exhaust shop to do the work, I'm opting for a glasspack and SS tip. The 18"glasspack has the louvered design and will have just enough room after the CAT. The exhaust tip is 2.5" inlet, 3.5" outlet and 18" in length. I may have to extend the pipe a few inches with a small section of 2.5" and a couple of couplers. I got the tip for just under $12.00 (must be a clearance on eBay) and the glasspack for $27.00 and change. I'll do the install myself. Hopefully it won't drone badly on the highway. I'm optimistic that it will be ok since the Megan (although it has a larger chamber) is basically a glasspack, plus I just installed the CAT and the turbo is supposed to quiet things down a bit too.

Excellent job looking into the exhaust issues and tackling the others.

The catalyst readiness check is the last one to be checked and sometimes takes a couple hundred km to go through. Cross your fingers but like you said time will tell.

You can always use a scanner to monitor engine readiness checks and see if it has passed or not

Thanks Trevor. Interesting thoughts. I hadn't thought of looking at the readiness data. Torque does display that info. Before I changed out teh sensor, I was getting a steady 0.0V. The black wire on the sensor was literally hanging on by a strand of copper wire. It had been twisted so many times, that the conductor just broke.

Exhaust concept

While awaiting my exhaust parts, I got thinking how neat it would look to have a 'dual exhaust' effect happening. I did a little mockup of what it might look like with two 3.5'ish tips. I think they look a touch big in the pic. Maybe 3" tips would look better. I was under the car this evening and there's definitely room for the piping.

Feel free to express your thoughts. I have broad shoulders, lol. Basically ignore the tip on the left if you want to get a sense of what it will look like with a single tip.

I like it :)

[tmontague]

I second that!

[06YarisRS]

Thanks guys. I really like the look too, although it does sort of violate my policy of keeping the car stock- looking. Decisions, decisions.

Better flowing exhaust

Wish me luck. I am going to attempt the installation of these parts myself. I picked up a few clamps and new bi-metal blades for my sawzall.



I ordered another tip the same as the one pictured in the event that I do decide to go with the 'dual' look.

Exhaust Redo

Well, stainless steel is a b**ch to cut. I trashed 2 new sawzall blades and had to finish off with my hacksaw. Thankfully I cut the aluminized pipe to install the new inline muffler first with one of the new blades. This is not the 'funnest' job, but I should have great flow when done. It's sad that a Megan axleback had to be basically destroyed in the process, but it would have cost me much more for another trip to the exhaust shop to have another piece of pipe bent and installed.



New 'muffler' installed



Extension for tip



Tip installed...Joking...the pipe will be cut back so that the tip will just slightly protrude from under the bumper cover.



Update

The car is definitely louder than with the Meagan, butI'll test drive this afternoon to see what it's like. My AFR and boost gauges have arrived, so I hope to start installation on those tomorrow.

A bit of a hatchet job on the exhaust, but my budget isn't big enough for a full SS, mandrel bent and welded system. None of the clamps and such should be visible when the car is back on its wheels.

Looking good, grab a sound clip when you can!

Will do. It sounds great outside.

I'm going to have my neighbour weld the tip and extension piece of pipe on. I've discovered that clamping stainless steel onto aluminized piping is a no win proposition. My tip got loose. The car is also a bit too loud for my liking, so I am going to have to look into another muffler solution in the not too distant future.

On the upside, I hit 8 psi. The car pulls really hard but the shifts can be quite firm. I've become very adept at manually shifting the auto for smoother shifts. It may have something to do with my poly filled dogbone, though. If the auto dies, I'll be looking at swapping in a manual with upgraded clutch.

I'm still struggling with idle issues. The car will run great until it gets up to temp and then it will occasionally (every few minutes) drop idle and it may stall at an intersection with A/C on. I'm doing some logging to try to figure out what's causing the rpm drop (stumble). The car usually takes two starting attempts and is very rich at startup. I will try pulling some fuel in the very low rpm range and see if that helps. Other than that, the car runs great and is sometimes scary. LOL

Ooh...very nice! Thanks. I wish they had an actual picture though. I can't see the one in the pic fitting.

Short video clip of accelerating

Please excuse my old weathered hands. LOL! As mentioned in the video, I did not mash the throttle and I'm still a little timid with the car. But, it really pulls and highway driving is a blast. I actually have to let off the throttle when climbing hills. I was up to 140 km/h in a flash on a long hill. Once I get a little more comfortable with the car, I'll open it up a bit more and do another video.

I am going to get a muffler installed because it is too loud in the car. Actually, I would say it's just on the edge of being too loud.

As an aside, I discovered that a couple of gas stations across the border, near my parcel pick up spot, sell 93 octane. Bonus. Speaking about pacel pickups, check out my next post for goodies acquired.

Do you not have 94 at petro Canada out that way?
Used to be Sunoco but petro has it at many stations here in Ontario.

No such luck here. We only have 91. Only you, Alberta and Quebec get 94 from Petro-Can.

Wideband AFR and Boost gauges

I negotiated a decent deal with Prosport. They gave me about $50.00 off.

Unfortunately, this means that I have to redo my gauge mounting. I have another driver's side upper glove box cover from the original dash in my '06. Fortunately, it was about the only part of the dash cover that is pretty much blemish free. If I had only kept each gauge about 1/2 cm closed to each other, I would have been able to add these two new gauges.


I had to get these gauges as torque's response times are way too slow.
