whats up guys , i have n o5CS with catbypass and k&n filters and i ordered two magnaflow mufflers i wanna install instead of the stock mufller...
need your opinion if i should go ahead and install them

 

If you want it louder, then you should install them. It all depends on your situation. My wife drives our CS, so I don't think that would be an upgrade she would like.

 

is it gonna effect my performance?? any increase in hp or same as stock, though i prefer louder sound and deeper...

 

magnaflow in my experience has a little higher pitch in high rpm and sounds louder in low revs. if you want it to sound italian, then the higher pitch would be for you. if you want to make the V8 sound like its out of a chevelle, then the louder low revs are for you.

neither are really porsche but its completely a matter of preference. if you ordered them, then you're probably going to instal them.

 

im in for the sound but im affraid its gonna effect the car's performance, although they high flow mufflers gives more hp and flow for the exhaust.
