Topspeed Pro 1 Exhaust or Fabspeed

Before you buy anything (unless you just need an excuse to upgrade the sustem) get underneath and wiggle the heatshields around the intermediate pipes. I had a rattle on the 04S and it was the metal shield on one of them. Drove a very small piece of metal between it to tighten it up and no more rattle.

In order to come full circle, had my Boxster with cat bypass pipes and ebay manzo exhaust pass the stringent California Smog Test with flying colors.

BTW, all the techs at smog place loved the sound of the exhaust note.

Congrat's on passing!

Most test stations will ignore the visual inspection fail as long as the car passes the emissions test.
