Custom Catback System

[Sabretooth]

Question at hand:

Me and a friend were having a discussion about exhaust kits... And how the Yaris is an axelback, but he says just go with a custom catback.

Simply buy a TRD muffler and have a shop build a catback system for it, of course staying with the idea of a high-flow cat.

Would the be reasonable, and at what price would i be looking at estimated for a shop to build one?

[ChinoCharles]

You'd be better off getting the whole thing built from scratch. You shouldn't pay any more than 300 or so for a full system. That TRD axle-back will put the price of the job way up there.

[DJ_Trizzak]

I'm planning to do that - buy a trd exhaust then add a cat back

[Moose]

Instead of buying the TRD axleback, you could just buy a Borla universal muffler and custom-shop the rest, and have the same thing, for 1/3 the cash. :wink:

[Sabretooth]

Well now step two, what muffler would be best for such a small package, I basically have two qualifications for a muffler I would want:

1. It dont sound like a Honda Civic
2. That I doesnt have a 4 inch pipe sticking out 3 inches from the back of the car, just looks silly.

Also, What would happen to warranty if you added the exhaust system?

[largeorangefont]

If you have a midpipe made with a high flow cat it should be between $200 and $400 depending on what type of cat you get. The pipe is pretty simple to bend up, then throw the TRD axleback on. If you go catless it will be $100-$150 for the midpipe.

i had a custom catback made for my GTI (didn't replace the cat itself tho). i had them put on a Magnaflow muffler with a simple twin tip (looks like the VR6 tips). whole thing with install was just $190.

before i sold it...

here's some pics of the install

a look from the back...

[Kaotic Lazagna]

the sound was nice and deep, not like a rice-rocket.

[ChinoCharles]

Those tips sit perfectly. They did nice work.

[Kaotic Lazagna]

yeah, they did. heh. but i'm not sure what happened to the shop. i tried going back there, but they weren't there anymore. dunno if they moved or got shut down....

For those of you who stated this above...
if you are going to buy an axle back then replace cat back with something bigger, how about you just give me that money for the cat back instead? you are still going to be bottle necked down to 1.5 at the axle back, to do it right you need to run AT LEAST 2 inch off the resinator ALL the way back to a muffler that has and intake of 2-2.5 inches, but all the axle backs for our car just bottle neck just as bad as the stock right down to 1.5inch pipe

[elsteverino889]

Me and Chino talked about this yesterday...one of my option is going to a get a custom catback exhaust but I prefer a greddy or some kind of other muffler bcuz TRD's muffler isnt even nice man.

i think they used the same-length piping on my custom job on the GTI.

Just got a new exaust installed today, it is from the resonator back, 2 1/4 Stainless tubing all the way back to a 50 Series Flowmaster muffler and dual stainless tips.

Sounds good man. I got mine w/ the same pipe size too. :thumbsup:

sounds good. how much did it total out to? oh, i like your rims!

[sf180th]

Hopefully it will sound better when I get my header in a few days, I like it now because it's not "tingy" sounding like alot I hear where I live

SICK! :eek:

[Black Yaris]

sounds better than mine :( looks like the same kinda tips I have, just not crooked :O Nice job there buddy, wait till you get the header it will change the tone as well

[CASTREX]

Other than a cool sound.... do you feel a difference?

[sf180th]

I think I feel a difference but not sure because I just switched to 94 octane gas two days ago and that makes a huge difference.

[Spades]

I am running 2" catback with a Dynomax Super Turbo muffler and a stainless steel 2" tip that barely sticks out from the car.

It sounds alright, but as soon as I get the funds I am swapping that Dynomax out for a Borla.

The Borla's have the deepest tone I have heard on 4 cyl's and they also dont have the annoying high pitched sound at 4k+ RPM's that glasspacks and the "fart cannon" mufflers that you see on most honda civics.

If you want good sounding exhaust without a high pitched whine for around 200 bucks installed, custom with a turbo style muffler is the only way to go.

If you go with one of those polished mufflers with the 4" tip, you might as well drill a few holes in the stock muffler and dump some ball bearings in it...cause thats the sound they make.

Also, alot of those mufflers you buy out of rice magazines dont have the flow capability that more known names like flowmaster and borla and hooker, ect. Most of those mufflers loose in flow rates and back pressure...magazines like Sport Compact Car and others have tested this theory.

In summary, Shiney 4" exhaust bad...2" turbo muffler w/ custom cat back 2" piping and stainless 2" tip, good!

P.S. changing exhaust piping from big and small often results in slower exhaust velocity which can lead to less HP. It is better the not change the over all exhaust size by much, and to not do things like get a header with a 3" outlet, buckle it to 2" exhaust, then throw a 4" muffler on the end.

[HTM Yaris]

when you crawl up under your Yaris , you will find that the exhaust is 1 piece starting from the header all the way back to the axle ................. Have fun :)

[Moose]

50 series? :eek: That's usually for dual exhaust/street rod applications!

It sounds great, though- I'll definitely give you that.

I wonder how it would have sounded with a 60 series- that's their "sport compact" series.

That fact is EXACTLY why you see nobody offering a catback system for this car.

[Kaotic Lazagna]

not sure if it was an actual pic, but i was looking in the most recent Siphon Mag issue, and DC Sports has a cat-back system for the Yaris (they were working on a LB, so i'm assuming it's only for the LB). but i don't see anything on DC Sports site...

Speaking of Siphon, what happened, first issue came out and didnt read a thing after that, been checking my local shops and nothing for about 3 months now.

[eTiMaGo]

I guess a target market of 4-5 different cars is too low to really get enough material, and/or reader base. So, either they fold now, or come up with an issue every 3 months...

i saw it at Borders bookstore.

3" piping too much? I get my custom installed this friday...

[redglare45]

3" piping too much? I get my custom installed this friday...

I would say 3" pipe would be over kill on our little car. I think 2" or 2.25" would be okay. Why are you thinking 3"? Will you be having forced induction soon?

[dngz]

3" will make ur tq go down...

[mafuzoulpa]

I got a speeding ticket so I didn't have the money to get my custom job done... I thought 2" is what we have stock... well anyway forced induction won't be an option until I can reduce my 2 to 3 hour commute to less than 1 hour.

I am considering 2.5" after my next paycheck... Im just doing everything I can to make the slowest car in my group to be the loudest... but I don't want to lose any power...

[Sabretooth]

In most states, loud will get you pulled over faster than speeding...

plus loud sounds rice.
go with a quiter but deeper tone, that usually does the trick, magnaflow does it right when it comes to mufflers.

I wouldnt recomend anything larger than a Folgers Can.

why would you wanna be the loudest? you are only gonna get in trouble with the law. if you are not gonna boost the car then a 2.25" diameter pipe will be best, in my opinion.

if you will be using fi then the 2.5" diameter will be ok. good luck!

[mafuzoulpa]

2.25 it is... our 240 and 350z have 2.5 so i guess i can understand why it would be too much for our cars...

can that make much of a difference though? I don't know the size of the stock piping, but it can't be much less than 2.25 right?

I actually have a magnaflow muffler right now... it sounds deep... sounds nice... people give me a lot of crap because of it (everyone in the group likes to trash american made aftermarket parts), but I still like it.

magnaflow makes some nice parts so forget the ones that talk crap about it. and the stock pipe is way smaller than 2.25". i haven't meassured it but when i saw it i knew it had to go.:smile:

[sf180th]

The stock pipe is choked down to 1.75 inchs after the resonator, I had mine redone to 2.25 inches and had a flowmaster 50 series muffler installed, sounds really good. This vid was before I had my header installed but you still get the point.

[mafuzoulpa]

awesome. how is the smell? doesn't sound too different from what I have now, which is good.. you plan on putting up another video pretty soon? kinda wanted to hear how it sounds with the header

[sf180th]

I havent noticed any odd odors or anything with this setup, I will try to take another video soon, it's been raining here the last few days.

I have a little update with my new exhaust as well, I went to a new guy who knew what he was talking about, and after he got my exhaust down he found out our resinator has the restrictive 1.5 shit in it, same as the stockand after market axle backs.... so we cut the resinator out and out a spherical joint in (because flex was taken out when the header was installed) and ran a 2.25 resinator and 2.25 stainless madril bent all the way back to a 13" 40 series flowmaster with duel outlet silverline tips... Throttle responce is much better, I notice a little more low end, not much, a little... now I want to get the long TRD CAI off and get a short ram on there so she can realy breath...
I will get some pix up of the exhaust here soon... BTW it cost me about $400
