From the sticky on performance parts for the 2.4L in the 2.4L forum:

Exhaust: The less restrictive an exhaust setup is, the more power will free up from an engine. Our 2.4 stock exhaust system is decent (has 2.5" piping), but it is restricted by the header, cat (in the downpipe), and the exhaust section from rear wheel back (which becomes 2.25" piping and has a restrictive muffler)

Which one is better? Thay all pretty much work -- no one has done a test to compare them against each other.

 

They all see pretty much the same gains. Just pick the one you think sounds the best.

 

run open downpipe, youll be good

 

Hope you don't have neighbors

 

my neighbors love my ark n2, esp when i leave at 4am

 

An Injen or K&N intake is your best exhaust.

-_-


truth.

those of you that have one will agree.

 

what

 

Go with Magnaflow if you want you remain a little bit more low profile. The exhaust sounds deep and doesnt look like a Folgers can welded as an exhaust tip

 

what

 

intake=wicked exhaust sound


catback not really needed until you commit to intake, header/dp and a tune.

a coca cola bottle

 

brick u make me lawlz

 

its true my bro has one. sounds really good and it is just the right noise. get that first and go from there(if you dont have yet).
