Exhaust Mufflers, who has the best one..... Options

[Phantom4]

Hey Boys and Girls can you guys help me out i am looking for a nice Muffler but don't know wich one to choose ...

So if anybody got some pics of yo 6thGC mufflers please post
i want to see who has the best Muffler

Since you're new, I'm going to help you.

A muffler is only a muffler. They have different sound tones. Some are deeper, others are higher pitched. You will find that most people on this site don't care too much on what it looks like, but more of how it sounds and how it performs. If you want a good exhaust system, then you need just that. Find a GReddy SP that is used, or do a custom job by finding a muffler and a high-flow cat. But IMO, it doesn't matter what it looks like.

Plus, make sure that you post in the correct forum. This doesn't belong in exterior styling, and I don't have the power to move it.

both the greddy sp and sp2 catbacks are discontinued and are pricey to find new, so i would get a custom exhaust. i personally like borla mufflers, but like verde said most dont care what it looks like, more how it sounds.

Muffler should consist of three things

Performance, sound, and looks. If it doesnt have all three, its not worth your money.

Here is mine HKS CarbonTI 3" inlet 4.5" outlet. My car is turbo, they make smaller versions for NA



Good luck finding a muffler you like

My Greddy SP2 Catback Exhaust.









Good luck!

yea, im gettin the sp style, looks sexy

[Phat_99CeliGT]

i have a Tenzo R 2.5" in 4.5" out.
doesn't sound bad, i like it, but i have an SP2 sitting in my garage, so i think im gonna trade them out this week.

Magnaflow race series muffler... sounds great looks great.

From perhaps the best writer I've seen for explaining technical issues clearly:
----------------------------------------------
THE MUFFLER
The key part of your exhaust system is the muffler. The muffler is the can at the end of your exhaust whose main purpose in life is to make the exhaust noise quiet. To be the whisper-quiet device most car owners demand, a typical stock muffler must have an intricate, labyrinthine flow path to help slow and cool the hot, vibrating exhaust gas. It contains baffles that cause the exhaust flow to reverse direction and intermix. These are great for reducing noise but are not so great for flow. The twists and turns the exhaust must endure in a stock muffler are restrictions that cause excess backpressure. You can run in a straight line faster than you can run in a tight, fun-house maze, right? The same goes for your exhaust gas.

To produce the most power, an exhaust should have minimal restriction on the exhaust flow. Restriction hampers the burned exhaust gases from exiting your engine, causing some charge dilution with the incoming fresh fuel air mixture. If all the exhaust gas cannot escape from your cylinders, it dilutes the flammable power-producing intake mixture that is trying to come in. The diluted mixture does not burn as well as a pure mixture. This causes a loss of power. You don't feel so energetic at a packed club with lots of cigarette smoke, sweaty bodies and hot stuffy air right? Neither does your engine.

With greater restriction, backpressure is generated, making the engine work harder to pump the exhaust out of the cylinders. That work could be used to turn the wheels instead.
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 mufflers quiet the exhaust by absorbing high-frequency vibrations in heat-resistant packing, usually consisting of stainless-steel mesh and heat-resistant ceramic fibers.

They typically have an inner core that is straight-through with no baffling at all, much like a straight pipe with many small holes in it. 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 fiberglass wadding (hence the old-school term, Glass Pack) or, in the better mufflers, stainless-steel mesh backed by ceramic fiber to help further absorb the sound.

On straight-through mufflers, the longer the muffler and the bigger the can, the quieter it is. The length usually has no effect on backpressure, just noise output. These absorption type mufflers work in the same manner as the silencers used on guns. If a silencer had baffles that impeded bullet travel, you would definitely have problems! The same is for a perforated core absorption muffler, straight through, no baffles, no restriction, and no backpressure.

It is best to avoid straight-through mufflers that have a louvered core. Many old-school glass packs suffer from this design. Some spiffy polished stainless and big tip mufflers on the market also have these. The louvers generate quite a bit of backpressure because they stick into the exhaust stream and create considerable turbulence. Even though these mufflers are a straight-through design, they can have more backpressure than a stock muffler.

When buying a straight-through muffler, look for one with a perforated core if you are interested in producing more power. A good, properly sized, perforated-core straight-through muffler will add only about 1 to 2 psi of backpressure to your exhaust system. Mufflers like the Walker Ultra Flow, Thermal, A'pexi, Borla, Edelbrock or MagnaFlow are examples of good, low-backpressure mufflers with an absorption design. Many Pre-made exhausts like A'pexi, Tanabe, Greddy, Borla, MagnaFlow, Thermal or HKS also have mufflers of the free-flowing absorption design.

An old-school type performance muffler, which is still very common in speed shops, that has seen better days is the Turbo Muffler. This is a less restrictive version of a stock-like reverse flow muffler. In the old days, these were well flowing mufflers, but now the new-jack perforated core, straight through absorption types, has superseded them, Many old-school domestic shops will try to sell you one of these as a hot set-up, but they should be avoided, just like the louvered core glass-pack.

A disadvantage to the straight-through muffler is that it is often louder than a reverse-flow muffler. Usually a straight-through muffler needs a small sub muffler or resonator to keep the exhaust quiet. A resonator is usually a small, perforated core glass pack placed somewhere in-between the catalytic converter and the main muffler. Like the main muffler, the longer the resonator, the better a sub muffler will be for noise reduction. A Walker Magnum Glass-Pack is a good muffler to use as a resonator. Almost all of the pre-made performance exhausts feature resonators.
----------------------------------------------

The only problem I have with his explanation is the resonator terminology. While the word is often used to refer to any sound suppression device between the engine and the muffler, it is actually a reference to a specific type of sound suppression. Oddly enough, the technology is based on resonance. A true resonator, which is what Celicas come equipped with, is a hollow chamber designed to bounce sound waves off each other, cancelling them out. Glasspacks and the like are designed to absorb sound waves into the insulation. You can determine which round metal cylinder uses which type of sound suppression by tapping it. A resonator will ping like a bell, which a glasspack/muffler will make a dull thud.

Yep, I love my Magnaflow.

[BlackCelicaGT94]

My muffler is custom made and I get a lot of compliments on it. Its a very clean sound! I love it

[Jaws4God]

Magna Flow with custom 2 1/4" cat back and 2 1/4" resonator...

Sounds and Looks great.

Another vote for the Blitz Nur Spec R, with a 3" decat its transformed into a flame spitting monster!

i have tanabe racing medallion muffler 2.5" inlet with 2.5" straight pipe. IMO that's good enough for me
