Default muffler style vs. canister style...

a friend of mine told me that it is better to get a muffler style exhaust like the greddy evo vice a canister style exhaust like the apexi n1 for an n/a car...i forgot the reason he told me...i was just wondering if there is any truth to this...does it really make a difference performance wise?...any help would be greatly appreciated...thanks...

All that really matter in a muffler is a straight through design that use a preforated core and not louvers. Otherwise it is all style and sound!

Indeed. Make mine a Brullen.. Wait, I already did.

..or watch the classifieds for a lightly-used Stromung, Borla, or other eqivalent decent muffler/cat-back system. They pop up fairly often.

I don't remember what the Apexi N1 looks like, but everything I've read about it says it's loud, loud, loud.

Canister mufflers are generally lighter, contain less sound absorbing material (louder), and generally have lots of different frequencies to make the noise it makes somewhat distasteful. You can buy a "straight through" muffler that has a large body like the typical muffler. (you can get mufflers that are a straight through design but have an angle to the inlet and outlet, and these will muffle noise a little better than a muffler that you could see through both holes) These will generally give better sounds due to the basic design of the muffler. It is generally made of heavier gage steel and has a lower resonant frequency than the thin steel used in canister types. A lower frequency will reduce or elimanate any "tinney" sound quality from the exhaust note. Another example would be hitting a 55 gal drum vs a 35 gal galvenized trash can. Hitting the drum sounds almost like an instrument when compared to the trash can.

As far as performance, there would not be much difference, you would gain something from the lighter weight.

EDIT The volume of the larger muffler also adds to a deeper sound.

Imprezas with N1's have a tendancy to get pulled over more by cops... Seriously.
