    How are the CMI's holding up now? I always wanted a set when I had my outlaw but always heard the had leaking issues.

    I don't remember too many issues with the CMI's... the E-tops would leak sometimes but the sport tubes I haven't heard any issues from. Most of the leaks I know bout are from the manafold style headers (Eddie Marine, IMCO, Dana etc) where the elbow meets the manifolds. I know on my IMCO's I always had a spare set of gaskets, those SOB's leaked like a fat man getting in a row boat.

    Sport tubes where known to crack mainly on the 525's haven't heard many issues on the 496 Sport Tube, but CMI came out with a similar setup as the Etops mainly because of the different tailpipe configurations. The Etops are actually the good ones although no header is safe from the saltwater. This is where the leaks are mainly caused from.
