Muffler Poll

Custom flowmaster dumped before the axle.

 

Inputs? Anybody?

 

In my opinion, no.

I installed an 18" Magnaflow with the stock tailpipe on my 2.7 and lost low end torque. And even though when I reinstalled the stock muffler and cut the tailpipe behind the rear axle, I still got the low end back.

So from this experience, I learned that the engine needs some exhaust backpressure for low end pull. If you open up the exhaust, you'll likely gain more performance at high rpms, but it will come at the cost of low end torque.



I'm running a long tube LCE exhaust header before I had changed the stock muffler...




It keeps the exhaust pulses in the runners separated from each other for a longer distance. This creates a resonant tuning of the pulses which lowered the rpms needed to achieve peak torque by 650 on the dyno. But even with the exhaust header, I still needed the stock muffler to provide enough backpressure for efficient exhaust scavenging at low rpms.

I had a wicked flo and I was not happy with it. Went with flowmaster original and like it a lot more.

 

2.7 liter in 2004 tacoma Flowmaster muffler flowing to dual pipes. Looks and sounds great, nice deep rumble and doesn't sound like a 4 cylinder.

 

I tried a large 22" long MagnaFlow. Deep and mellow.

I called my local muffler shop to get a quote and he said he has a magnaflow replica same design stainless steel just no warranty for 100$ out the door with a tip he didn't give me a brand now but has anyone tried replica magnaflows?

 

I put it on its nice and smooth deep no rasp not tin sounding either no drone at all feels like it might have a tiny bit more low end power as we'll

 

just put a magnaflow on my 2.7 ,great sound , not to loud in the cab.love it!

 

00 3.4 supercharged 14" long 4" round magnaflow turned down before the axle

 

I wonder which muffler sounds the closest to the TRD

 

Probably wouldn't be to hard to find out who makes the TRD mufflers/exhaust systems for them.

 

Any suggestion which one sounds the closest to the TRD

 

My guess would be Borla, I'm pretty sure borla was making the TRD exhaust for a while. But I could be wrong...

 

Getting a complete system from y pipe back. Magnaflow cat, vibrant ultra quiet resonator, Borla Pro xs muffler. Exited out through the side of bed in front of pass tire

Will post results/vid when done.

 

I wanna see this, Something I've been wanting to do for a while, I wouldn't be changing my muffler though, just getting the mandrel bent piping needed, I'm very pleased with the sound of this 14"x4" round Magnaflow muffler.

 

Any videos se we can hear how it sounds

 

search YouTube

 

I just did thanks im liking the sound more of the borla than the magnaflow
