I have a 2.4 SS and i installed a K&N intake
What is the highest preforming exaust system to work with my car. Corsa, Magnaflow etc.
Pros? Cons?

 

not sure but i like mine. i got a zzp midlength downpipe, zzp highflow cat 2.5" and the gmpp performance exhaust. and she's got some pick up and go again. it changed my power band though, don't really get the extra umph till 4000rpm now though

 

moved.

 

Yeah Same thing with my intake dont get the performance until 4-5000 rpms

 

with my generic intake my power was still at 3000 wasn't till i did the exhaust work that it changed to 4000 but its a huge difference when excellerating its like bam more power

 

Now the question is what brand to go with. they all generaly run the same sizes and setups right?

 

depends, your gonna get better performance from a mandrel bend compared to a crushed bend. also depends on what muffler they put on there and of course what diameter exhaust you go with. i wouldn't go anything bigger then 2.5". and sound is obviously differen't depending on the setup you go with
