Lookin for an exhaust system
I've been thinkin about upgrading my exhaust to Borla headers, a high flow cat and a Stromung muffler.
Any suggestions for the cat?
Does anyone know where I could get these new or used i.e. a website or reliable muffler shop?
Thanks!

honestly, the first thing is...
if you get too large of an exhaust, you'll lose torque on the low end.
probably the most effective thing you could do is get the stromung cat delete pipe and leave the rest alone. cats are a HUGE restriction of power on all cars...
a difference between the borla type and stock headers is a matter of WHERE you want power.
the borla headers give you a bit more higher rpm power, but kills some of the low end power.
the stock headers give you more low end power, but kills some of the high rpm power.
