Custom Axleback - Pics and vid.

[largeorangefont]

Here are the pics of my custom axleback. We simply cut off the OEM muffler and welded this on in its place. We were able to retain all the factory mandrel bent tubing.

I used a 2 inch Imco Turbo series muffler part# T-934. It is a center inlet / offset outlet. The Muffler core is 12" X 7 3/4" X 3 1/4". The total muffler length is 16", and the tip is 2" tubing with a slash cut.

This is quieter than a Magnaflow, with no droning. The change is barely audible in the car with the windows up. It gives a deeper tone, and better sound but not enough to attract any attention from the law. I have since painted the muffler and tip black, so it looks stock to anyone that isn't familiar with the stock "pumpkin" muffler.

[PETERPOOP]

nice idling tone

[ddongbap]

DAYUM!!!!!! That car went low when you sat in it.

On a side note, my friend drove my car away from me the other day. It really does sound like the Yaris commercials.

For those who might like to copy your custom muffler, what is the part # for the muffler?

Also, what is the length of the tail pipe (from can to tip)?

BTW, it looks so much better with the can painted black!

great sound! I totally love it.

[Letsrock]

Nice killer sound. Great job.

[baked_limabeans]

i might copy you.

[AznGouki]

Whoa, lookin sharp man

[largeorangefont]

i might copy you.

Do it!

[eii]

Deep. Nice. You should've followed that mini van and raced it.

Probably would have lost.. :frown:

Very nice, low key exhaust. I really liked the paint job. :cool:
Did you notice any loss at low RPM's?

Thanks! There was no low end loss at all.

Both yours and the Dynomax 1777 actually fit better up into the stock heat shield better than the USDM pumkin muffler. After 15,000 miles my Dynomax is getting a little louder.

Yea, my muffler sits right up in the channel near the framerail. Everything back there is covered in heatshield, like the car was made for this size muffler.

great sound! Love it!!

[TheSilkySmooth]

very nice vvrroom. I want a boy to put a turbo can on MY 3 dr. Yaris for me. + I like the gray wheels. I want to have a nice muff too like everybody:smile:

nice..... :thumbup:

lieky

Do you know how many CFM this muffler flows? I cant seem to find any info on it.

Here's a pic of my axleback: 2 1/4" Dynomax Super Turbo Muffler (I was too impatient to wait for a 2" DSTM, so I purchased one from a local Advance Auto Parts store for $50. It's not the lighter, single-wall $20+ dollar version. I hacked off the muffler with a reciprocating saw (w/ a metal blade) and drove it to the muffler shop where the tech welded on a pipe configuration that would allow such a large muffler to fit under my car. And then I took it off and painted the entire axleback with a high heat, high gloss black paint. I love the end result.

Several Yarii around Dallas have removed the pumpkin muffler and simply run a straight pipe from the axle-back coupling to the exhaust tip. Sounds really good, and doesn't seem to affect performance negatively. Obviously, its a weight reduction, and it appears that the pumpkin is mainly a noise-reducer, so not sure if it would have any emissions effect (I doubt it.)
A dyno run needs to be done to determine if it helps/hurts performance, but that would be very simple to do a with/without pair of runs.
In Texas, the car would probably pass inspection if it passes the tailpipe sniff test, unless the tech decides to look for the muffler and knows that its missing. Even then, it would probably pass, but that's the only problem I can see, legal-wise.
Anyone have more experience with this?

[lilredrocket]

Actually in Texas if a vehical is newer than 1996 when they started using OBD2 in cars they don't use a sniffer. Also if you remove your muffler in Texas you should fail an inspection if the inspector looks at your exhaust

[ozmdd]

Lil red, it must be different out in FW. Here in Dallas Co., we have the tailpipe sniffers no mater what the year. We're one of the EPA smog counties, so it a little more stringent. We have the lame California-type low-emissions gas too. Cleaner, but less HP (teeny-weeny bit, albeit.)

Also, LRR, you would still have a muffler and 2 cats in the midpipe section, so I'll bet a really clean weld job would get by a lot of inspectors. If they ask, just say "the muffler is right there in the middle! " :)

Your idea of either keeping a stock muffler set-up in the garage for inspections or clamping/welding a hollowed-out muffler body around the straight pipe is the best idea.

[lilredrocket]

I'm not saying you are wrong but I am a certified state inspector and I have done inspections in both Denton and Tarrent counties and never used a tailpipe sniffer for inspections unless the vehical was older than 1996 or the OBD2 link was not reading.

So if I move to Austin my supercharged Yaris would still be illegal? :tongue:

[lilredrocket]

Shouldn't be... I'm not 100% sure they have emissions testing there. It's not a state wide deal it is more county-city level. But there is a safty inspection across the state. There are 2 members that are boosted in TX not sure if either one has had to get an inspection yet

I used the little $25 Dynomax muffler and installed a Harley baffle to tone it down nicely. The baffle also adds a little back-pressure that may be lost in the high-flow muffler. Not sure if it matters much in that respect.

Just installed this very muffler along with some 2" resonator-back piping, and I have to say that I love the sound and performance so far. :thumbsup:
