lookin to get an exhaust. Just wondering if it would pass smog or if I'd need to keep the old one to put back on come smog time. I'm talking about two brothers, micron, yoshimura, bla bla bla. you know all of them. I know acrapovic has a legal one.

 

Read the disclaimers on their websites. I haven't found a "legal" one yet that conforms to federal guidelines. If you gotta do emissions testing in CA then I'd keep the stocker. Generally the po-po won't bother you too much unless your pipe is ludicrously loud.
