I mean for a 173 HP 4 Banger, she is pretty quiet, more quiet than what my stock sunfire was.
So I'm guessing it's a lot more quiet due to being very restrictive with the exhaust.

Anyone have a cutaway pic of our stock Muffler?

 

i heard a sound clip of a 2.4 with no exhaust just right outta the header... jesus it was loud but sounded sweet. lets say it was about 2 or 3 times as loud as the stock 2.4 exhaust.

im assuming its chambered....?

 

our mufflers are really not restrictive,its the combination of the downpipe and stock exaust system that is restrictive

 

in the stock dp it steps down alittle and that o2 sensor is pushed into the tube so thats restrictive and that huge arss muffler on the car lol!!

I tore the muffler off, granted I lost some low end, but the mid/high end power is incredible.

 

I also tore mine off within a month, and the resonator, and just welded on a straight pipe and FlowMaster 40 series muffler, with the stock tip back on. Loud, but yeah, some low end was lost.

 

i kept the resonator, the sound is very distinct.... cross between american muscle / import.

But by no means ricey sounding.....but yes, VERY VERY loud.


I havnt heard the exhaust at WOT, since in neutral/park it only does 4k. and i had the woman do it.

 

So would you recommend that if I want to keep low end torque but also add HP, I should just replace the muffler with a another one, perhaps the Magnaflow muffler?

 

In short, yes. Id actualy recommend a full exhaust.

The loss of backpressure is what nets you the loss of the low end power.

 

I Have A 2.0 Ss.sc Stock Muffler Lying Around If You Didnt Want To Go Crazy Lol

 

:::sigh::: The 2.0 and the 2.4 shair the same catback. Its the same part # from Gm if you have a SC car or the 2.4. The manifold's are also the same part. The cats are different depending on where you live (ie California car)
