Don't get the steeda side exhaust. I bought it for 750$...worst money i've spent in a long time, took it off after 2 months. The build was terrible, pipes didn't line up right, one side was too low and would hit everything, no matter how much you tried to adjust it. You raise it up os it doesn't hit speed bumps (my car is at stock height) and it rattles agains the floor. I eventually just cut off the tips and made a staight set side side exit pipes, looks just like the real set up. It sounds mean now, but has drone on the highway.
My suggestion to you, is to buy a pair of mufflers and tips that you like and have a shop make the connecting pipes. Therefore they'll be made to fit your car and can accomdate for any mods you have (low drop, subframe connectors, etc).
thats probably the safest bet.
Just my two cents.
