Hi, srry for asking so many questions over the last few days but am still a newb. I am wondering what is better the dual rk sport exhaust system or the dual magnaflow system? what would be best for the most performance?.

for most performance, the only things that matter are:

size,
shape,
material,
weld quality,
weight.

that being said you won't notice a difference between the two because they are the same size piping and almost identical design. The best for performance would actually be to go to a single outlet exhaust because you will have less weight sufficient flow. But I understand why you would want duals since it's a sunfire GT.

my advice is go with what's cheaper.

that has to be the worse sig ever

yea, well if there the same i will go with the rk sport system, its like a few hunderd cheaper then the magnaflow.

the one from rksort is a magnaflow

i have one and it sounds real nice and low

but for performance single is better
