I want to get a sporty exhaust system when I get my new box.
The only question I have is do you guys think I should go with the Scion XB Catback from Magnaflow or the TRD Axle-back Exhaust System available at the dealership.

Please post your thoughts. 8)

Given the two choices I'd say Magnaflow. I haven't heard great things about the TRD. I hear it doesn't hang correctly which can cause it to come in contact with the rear bumper and melt it. That's just what I hear... If you do go the TRD route don't buy from the dealer. They are always way overpriced.

if u r choosing between those 2, i would have to agree and say go magnaflow. although on my xb i just ordered an axle back from gabe at precision muffler. u should check out his webiste. www.precisionmuffler.com

Between the two choices you listed above, I would go w/ the Magnaflow catback system.

In about another month or so, I'll have some axlebacks ready to sell too.

Thanks for the support BangorXB.
Right now we have a special going on for the magnaflow Auto axle back, Check it out here: http://www.scionlife.com/forums/viewtopic.php?t=42836

i would make your choices

- magnaflow catback
or
- precision muffler axle back w/ magnaflow muffler

you can't go wrong with those choices

wow

wow Thank you. :P

I'm still loving my magnaflow cat-back. sweet note and awesome looks!

custom catback with a magnaflow muffler maybe? cheaper yet same look and sound,

just to add some extra info..
why is it TANABE, GREDDY, APEX, TRD,
and tons more quality japanese manufacturers NOT making
cat back, but instead they make an axle back.

until u see the dyno results i dont think anyone should speculate.
from wat i hear, catback makes u lose some back pressure,
i just thought that the companies i listed have been designing
exhausts for import cars for over 10 years, and they most
likely know what they're doing, i really dunno how long
magnaflow have been doing custom exhausts for.

i always thought magnaflow was the generic universal mufflers
u get when ur stock car rusts out and they give u a OEM REPLACEMENT!
thats just my opinion, i dunno if its 100% true or not, i thought i just
let u know so u might have a different pespective(from a NON magnaflow owner like me)

I like magna flow. :D

I like magna flow. :D

Obviously! :wink:

-THE DON

Funny, the generic OEM replacement on the Civic I had was only $30, yet the magnaflows are at least twice that. And the generics rusted thru after a couple of years.

here's some links u should read.

http://www.eautoworks.com/html/ORD-1-1-1-23462.cfm
http://www.modacar.com/products/Toyota/Scion/MODARES
(note i only see JIC being a catback system)

im sorry to tell u this, but many people who
buy things, swear it works and it works DAMN good.
whats next the TORNADO = HP?
i just wanted to emphasize that people aren't dyno's
theres no way u can feel how many HP gain or loss u have.
since thats the case, i just wanted the buyer to be aware of
dyno's and results. that way nobody needs to talk out of their ___.

FYI, here's some history on MagnaFlow. We've been working in the catalytic and exhaust business for 20+ years, and has offered everything from high flow cats, to exhausts and everything in between. There are many top name companies that actually sub contract us to manufacture their systems, both as OE and aftermarket. We may not be as known in the sport compact market as some of the other Japanese manufacturers but that doesn't mean that people here aren't capable of putting together power producing systems. As for gains on the xB system, take a look at the dyno chart I've attached below... brand new '04, automatic, only modification was the cat-back.

whats the correction factor. its 1? or 01.0x?

which dynojet model? 248?

Magnaflow has been at Precision Muffler and Brake since we opened 12 years ago and have never had one complaint about them. :D

i hope all this information posted helps people who are in the market of a muffler or exhaust system.

Can anybody tell me what it's like to drive with that drop off in power in the low RPMs? It looks like power comes on 500 RPM later with an aftermarket exhaust, but then continues to build after the stock exhaust power falls off. Issue is that low RPM power. How noticable is it? Any stalling issues? Acceleration? In general, minus the sound, was the vehicle with an exhaust more fun to drive, or less?

Thanks!

Proto in Iraq (for only 2 more weeks!)

That dyno does nothing to help in what hahajoey is saying. Your catback might make 4whp over stock but still might be less than a good quality axleback setup.

You see what I'm saying?

He said there's a reason japanese companies made axleback...maybe they made more power...but magnaflow would have to test both to compare...not just compared to stock.

Cuz I could ____ in the tank and dyno +2whp but that doesn't help me unless I compare it to somebody elses ____.

Ya get me

let's compare joe

ill put my ____ ina cup n u guys can shower yourselves w/ it.....quit fighting over an exhaust issue sheesh!

golden shower nukka

the blacker the berry, the sweeter the juice

the darker the vegetable...the more antioxidants within...WTF

GO CUSTOM NUKKA

hahaha

Hmm, we're fightin over hp out of a 1.5 liter that has 108 hp at the flywheel!?!

And only one person has posted dyno results for proof!

and the truth is squirrel...its so minimal on a vehicle as is with a few bolt ons...that its without question more for looks, fit/finish and sound. Thats what your buying. Every dyno can be off a hp or 2 hear or there. dyno results don't even mean much with vehicles making 180whp let alone 100 from a 1.5NA motor. At this point it boils down to preference and sheer personal opinion. Its the reason why i posted sound clips so early on the Strup because it meant more then 1whp and the strup looks great.

i just wanted to help a scion guy out,
not tell someone to buy a product just cause
i have it and they should get the same.

i just thought a posted those links as a little help
for people who are reading, and im glad
showpao understands where im getting at.

its not the 1.5 to 5hp rating. and in fact, i posted a link
that had intake, header and exhaust dyno'ed.

im not out to prove anyone wrong, i just wanted to provide
an UNBIASED opinion.

just to add some extra info..
why is it TANABE, GREDDY, APEX, TRD,
and tons more quality japanese manufacturers NOT making
cat back, but instead they make an axle back.


This is because the ONLY flange on the OEM system is at the axle. And damage to the ceramic catylitic will void your smog warranty and cutting the OEM exhaust so close the cat could jar the insides loose and that a $900 replacemtn piece.

That being said, www.vibrantperformance.com will be offering an axle back in the next few weeks as well as a cat back (how the 'coupling' works on the cat-back is beyond me)

I know this cause im their guienna pig! They got a nice xA/B front bar too!

the coupling is nothing more then a curved piece of metal stock with a groove in the middle. When wrapped around the attachment point it pulls the flared ends of the axle back and "cat" to axle pipe together when bolting it together. Its fairly primative.

As i stated earlier...when using a stock size piping it boils down to quality, sound and looks. Thats what your paying for.

It will be 2" as that is what the OEM piping is before the cat (after the header part)

Remember, im not an exhaust god...lol....im just psoting what they were saying yesterday...lol

Primative, yes. But if the flared piece is not correct, say good buy to that gasket and hello to a burned bumper. :shock: The trds,sometimes, do that now, with their design. :?

And you'll prolly need to replace the "ceramic"/metal gasket at the attachment point also. Most don't and end up with melted bumpers.

But there is a work around that, especially if you want to pay a few more dollars. Ken at Michael's Muflers has the solution to the problem.

I have less than 1/4 inch clearance on both sides of my oblong tip, and have yet to melt my bumper.

My xB just came with a POS universal muffler and nothings melted...

Disclaimer: I know nothing about tuning cars. Please correct me when I am wrong.

I was thinking of getting Headers, Exhaust, Intake but after looking at the charts and reading the web sites posted I am thinking of just staying stock. I have no dreams of making my car break records at the track. I just wanted to give the car some more get up and go. If getting HEI is going to kill my low-mid rpm's like those dyno graphs show then what’s the point? I have an automatic and I spend all my time 2500-4500 rpm's. If the stock set up gives me the best power in that range then there is no reason to switch right?

Am I reading the Dyno's wrong?

Thanks,
Jason

well from my hei i have increased power throughout the band , i have lost no noticeable low end , and my power starts kickin in just about 2500 so.... and with an auto everytime u speed up yer engine speeds up and if u slam yer foot in it it downshifts into the power.

A $200 Magnaflow muffler based axleback installed sounds pretty good to me.

you've got a shadow do ya brad? lol

everyone has shadows in the sun, :D A nice precisionmuffler.com axle back is always a nice way to go as well. Priced to go and shipping is not a problem.



I know that a 2HP gain is not a lot, but the looks and feel of 2HP is still more than nothing.

my $.02

you've got a shadow do ya brad? lol

Yup, its the peeps following me to get their $200 installed Magnaflow-based xB axlebacks!

2bills for a magnaflow? geez, is that even stainless steel?
i dont think i'd ever run that.... not even for free..
but thats just ignorant stupid hahajoey.

^^^^^^^^^^^^^^^^^^
its identical to precision but cheaper in price. i'd have to see quality first tho i suppose. i'm a poor guy so if the quality is there i'm down for cheap. i sold dzcustom a nice universal muffler he had installed and for 100 he has a lovely deep low pretty quiet exhaust it's basically just an axle back , he like it , and it has a tip that is soo far from the norm , it's awesome looking.

Its $200 INSTALLED, tax included, and stainless. Two peeps are running them, and will give me their honest opinion when I see them in a week.

Darren, you'll see both cars next saturday.

I like the looks of the TRD Sport exhaust but am wondering what is this I have been reading about melting the bumper? Also which muffler has the best low sound? I am looking more for a rumble than a whine.

well the melting bumper is a result or ____ty mounting , basically the muffler moves from side to side so it can hit one or the other side of the bumper thus melting it. a low sound depends on muffler , piping size and whether or not it has a silencer in it at the time.

For a low rumble I would recomend the auto axle back from Precisionmuffler.com. The low rumble is perfect and you never have to worry about melting bumpers with it either. :D

Melted bumpers are the result of improperly placed hangers and of the exhaust joint gasket being worn out and not replaced.

magnaflow all day

Yup. Always in stock at Michael's Mufflers.

Got them in stock! :D
