I ant to get a muffler for my xb. which one is better in performance? i'm considering hte jic or the trd. does any have either of these and do you guys like them? any input is apppreciated.

you can also look into getting a magnaflow muffler since they make them for trd.

I want to put a better muffler on my xB but I want one with good sound. I'm not a big fan of the rice burner sound so I want something that wont sound like a bug flying around. Does the TRD muffler have a good sound to it?? Thanks.

I was thinking of getting a muffler myself. I'm either going to go with a GTII exmag, mega power muffler, or hyper spec. All of which i believe are straight through mufflers. Is it true that getting a straight through muffler will make you lose hp and gas because it will mess with the obd sensor where your "check engine" light goes on. Also, i was recomended to get a chambered muffler since it won't cause that problem. Please help.

I am using the Magnaflow mirrior finish muffler with a ___ tip. Here is the link to the pics. Just copy and paste the link to your browser.

It is completly quiet at high RPMs, of course I also had the entire exhaust system done as well.

I would suggest reading this article, i wish they would publish all 7 parts, but the few they have up are really informative

To get the least amount of backpressure, most of the good, high-performance mufflers available today have what is called a straight-through design. These type of mufflers quiet the exhaust by the absorption of high frequency vibrations in a heat-resistant packing usually consisting of stainless steel mesh and heat-resistant ceramic fibers. They typically have a straight inner core with no baffling at all, much like a straight pipe with many small holes. The pipe is louvered or perforated when it passes inside the muffler's shell, allowing sound energy to pass through the holes but leaving the exhaust gas flow unimpeded. You can see straight through these types of mufflers. The louvered or perforated core is usually wrapped with either Fiberglas wadding, hence the old-school term Glass-Pack or on the better mufflers, stainless steel mesh to help further absorb the sound. On straight-through mufflers, the longer the muffler, the quieter it is. The length usually has no effect on the backpressure, just the noise output. These mufflers work in the same manner as the silencers used on guns. If a silencer impeded bullet travel, you would definitely have problems!

i like that tip w/ logo, looks dope

Nice Stylis. I like the sound files on the bottom of the page. Gives you a real feel of what it sounds like.

I think silencers do impede bullet travel... I thought we lose some power if we lose too much backpressure ???

I have the trd muffler on my xB. It sounds great, but the one thing I can't stand is that it's not anywhere near centered where the groove is cut for the exhaust tip in the rear bumper. In fact the tip is like a millimeter or two shy of touching the bumper. That's kinda lame considering it's made by TRD. I figured that they'd have the best fit for their own cars. Oh well. Anyone dealt with this and/or know how I can fix it?

speaking of lame, i notice that my stock exhaust is crooked. then i noticed that mine is not the only one...weak sauce!

don't forget to check out http://scionsporttuning.com and the SPFR cat-back exhaust they offer

don't worry about the ricey sound. Just go to a good muffler shop and choose which ever looks best because the resonator will give you a good, deep sound regardless of which muffler you choose for the scion. Obviously don't choose a cherry bomb muffler. I have the bomz racing muffler and I love it.

for those who don't have a centered muffler, you can help get it to center if you twist the muffler tubing where it meets the oem tubing with the clamp. try twisting it and retightening the oem tube to center the muffler. that's what i did to center the muffler tip.

I still would stay with the magna flow mufflers, they sound great and have a shine to match. And I have no problems with sound on the freeway either.

exhaust backpressure is a not quite so acurate term. in an exhaust system what is important is the timming of the energy pulse that moves through the entire engine, from the end of the intake to the very end of the exhaust. whew. when that pulse reach's the end of the exhaust it returns in the opposite direction. if it reach's the exhaust valve while the valve is off it's seat it slows , and/or in some cases reverse's the flow all the way back out the intake. that phenomon is known as reversion.
intake length , cam timming , and exhaust length & diameter [ i.e. backpressure] all share a part in an engine's performance at any given time. so you got to work that thing between your ears and do your homework and getz shiznitz that works together. i.e dyno tunning backed up and verified at the track. and certified with an accelorameter.


tha tha thats all folkz

remember , just because you dont see them dosen't :? mean they aren't WATCHING you

What about a flowmaster muffler? I have a 40series sitting in my garage, I'm thinking about installing that but I'm believe I'll have too much back pressure.

What do you guys think?

SammyPsycho: I was under the impression that the reversion wave became indeterminant after the header and going into the first catalytic converter. i.e. the wave going back up the pipe anywhere past the cat wasn't going to do much in the way of scavenging exhaust from the cylinder. Just curious, that was the impression I had gathered from reading not just that article but others as well. I'm all for tuning, but is there a point (along the exhaust, such as headers, or cats or even going out to the muffler) where tuning the exhaust system doesn't provide any noticeable benefits?

I have a quick question...

I just want to install a muffler...not the whole cat back at this time. Is there any decent and nice looking "bolt-on" muffler for the xB?

Looking for something that has a throaty deep sound ..rather than a high pitch screamer.

Let me know...

I think the only one available and not on back order is the TRD muffler from the dealer, but it is a magna flow muffler. Just to let you know.

Blitz Nur-Spec rear piece only axle back exhaust. It's bolt on, no idea on the sound, but Blitz is supposed to be really good.

I've seen online dealers selling it for $300-350 + shipping.

hey...does anyone here have a BLITZ NUR SPEC rear only muffler? cuz their website claims that with just the rear only bolt-on muffler..there's a 5-20HP gain...

they retail for $330 for the xB, but i've found this site that sells for $289

it's a nice looking muffler...but how's the sound?

20hp gain? sure there is. get it and smoke us all!!

here's the excerpt from blitz website...for the NUR SPEC rear only...

PRODUCT DESCRIPTION
The BLITZ® NÜR - Spec Series exhaust systems are available as direct bolt-on replacements for OEM exhaust systems. Our exhaust reduces back pressure and thermal stress. This allows the engine to create more power and torque by breathing easier. By utilizing extensive computer controlled design, flow analysis, dyno testing, and precise fitment BLITZ® exhaust systems produce maximum horsepower without dramatically reducing low-end torque.

The quality of the BLITZ® stainless steel exhausts is second to none. Rated as the highest quality, our exhausts perform as well as they look. Unlike conventional exhaust systems, BLITZ® exhausts utilize a slanted mounting design which eliminates unnecessary bends. The specially designed muffler and large diameter mandrel bent piping has no reduction of inner diameter in bend areas. The constant piping diameter size allows for superior exhaust flow superior then compared to crush bent piping.The most impressive feature of our exhaust system is the quiet tone with the silencer on, and its aggressive tone with the silencer removed. Performance increases very by application (gains of 5 - 20 horsepower are average). BLITZ® exhaust systems are designed for maximum performance, improved appearance, and an aggressive tone.

There are two types of BLITZ® NÜR - Spec Series exhaust systems available, the NÜR - Spec which is a rear section only exhaust, and the NÜR - Spec R which is a cat back system. The NÜR - Spec R system comes in two parts. This version also has a removable silencer for road / track use. Because the full system removes the silencer, it produces a fairly loud, deep sporty note.

Each BLITZ® exhaust is flanged and comes complete with all gaskets and hardwear. Providing the easiest bolt-on installation possible. All BLITZ® exhaust systems utilize factory mounting points and hangar locations. A fine balance of looks, power, and durability has been achieved through full stainless steel construction finished in a show quality shine.

hey, i believe you. i just don't believe them. trust me on this one. you aren't going to make 20hp by removing your entire exhaust on a scion. you aren't even going to make 5hp with an axle back. sorry. but it will sound cool.

bummer... i was expecting atleast 5HP gain... damn BLITZ

Just wait until I get my Dyno, it wi;ll show the gain. Scionara might take my car to get dyno ed.

2fixa: good point i have no dyno experience with stock exhaust . but i have seen the lenght of pipe after the collector affecting power &or torque. smaller engines are more sensetive to changes. longer pipes = lower power , short pipes = highend power . add a cat and f!@$ i don't know

just because you see them dosen't mean they aren't watching

I agree....They are probably failing to mention that the 20hp is on their cat back system mated to a turbo car with an upgrade.

anyone know how loud the exhaust is without the silencer?

Blue: you gotta note that Blitz did mention that the hp gains are 5-20hp "depending on application." On a Scion, replacing the rear muffler section will probably net you a gain of 2-5hp at most depending on what exhaust system you go with. Cars that can gain 20hp or more from just a cat-back exhaust are usually the turbocharged ones that come with really restrictive stock systems from the factory.
