5th & 6th Generation (2002-2006 & 2007-2011)Toyota Camry Discussion for years: 2002-2006 & 2007-2011
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
I am looking to install the 2540i Aero Turbine muffler to my 07 Se V6. Their claims of improving MPG and low end torque got me interested in buying their products. IMO the 2540i looks much better than anything I have seen. I have watched some clips of this exhaust and like the sound a lot. Very aggressive and mean when accelerate. The setup with this muffler is combined with a 27" magnaflow resonator. I also contacted Aero directly and they said the 2540i will be loud. Some suggestions I got was go with a longer resonator--27" plus ( but with that length wouldn't the back pressure be worse than a stock V6? The inlet also jump from 2.5" for 27" resonator to 3.0" for 30" resonator from Magnaflow) What kind of setup do I need to keep the 2540i that will give me better MPG and better low end torque without losing HP? And keep the noise level inside the car as close as to the stock muffler.

how come it will not improve MPG? the stock muffler is very restrictive and with something that let the engine "breathe " easier, MPG will increase right?
Isn't glasspack aka cherrybomb is very loud, and not something i would want.

I am no expert, but glasspack does not mean just cherrybomb. Their are others offering glasspack's and they are not by design loud...cherry bomb's might be though. Netforcer, TRD.... - can you clarify

...unless youve taken a torch to it, not that i know from experience

did a little reading and the quietest would be to keep your stock resonator and just change up the mufflers...
or get a silencer...
also to keep in mind...
the thing about going aftermarket piping and aftermarket resonators, is that you can get varying sized resonators which will all impact sound... so you can get the sound you want...

well according to that standard, if you removed the muffler all together than the it would be least restrictive, and improve mpg, but it actually goes down due to loss of back pressure...
so it is a dance... i.e. if you decrease back pressure a bit, and get a higher flow you will increase top end power, buy might lose a little torque and power at lower speeds...
the only way to really optimize it would be to try out various products and configurations on back to back dyno's to optimize performance, sound, mpg, etc...
so, if you want go aftermarket, generally i say go with a respectible company and look for someone who has done it to see what it will sound like... in terms of mpg, and torque, the changes will be neglible at best....
you should not expect too much from an axle back, and or catback exhaust...

Hmmm... it sounds like a terrible idea to change the muffler in order to get the benefit. The top end power doesn't really apply to my driving habit. I watch the tech meter goes above 3000rpm during accelerate but maintains below 2500rpm once the speed is stable--60mph.
I don't mind changing the exhaust, but if the cost is losing HP, or make the car performs worst than before. I don't see the purpose to tolerate the noise.
I tried to look for interior video of the 2540i setup and see how loud it is when the car is in motion. Best I found is http://youtube.com/watch?v=sGB8DY6XeWk
That video made me think about this product and drew me into aftermarket exhaust.
Does silencer go after the exhaust? Where should I look?

Sort of, kind of.
It's not back pressure that you want, it's max velocity/air flow.
Bigger Pipe = Optimal for higher RPM's | Bad for lower
Smaller Pipe = Optimal for lower RPM's | Bad for higher
Removing the muffler all together will actually be beneficial.
The goal is to get the exhaust out as fast as possible. However, due to the nature of the exhaust gas pulses, bigger piping isn't always better.
Every Tom, Dick and Harry backyard mechanic has an opinion/old wives tale.
Maximizing power with an exhaust sytem is done by having the maximum velocity of gases to scavenge the engine the most efficiently.
If the system is just piping, then too big a pipe will slow down the gases, too small a pipe will slow down the gases.
But the gas volume through the pipe changes with the rpm, so it isn't a simple or easy design.
The GEN6 mufflers have internal valves that are closed at idle and open as more volume (pressure increases), to maintain gas velocity.

the silencer actually goes into the exhaust opening, there are lots of different brands and manufacturers, some of them claim increases in mid range power.. but that is because it is a little more restrictive than the exhaust by itself... google exhaust silencer and you will see all kinds of things pop up...
if you want your car to sound a little more aggressive without the noise all the time, i think you might be happier with an intake...
