As the title states, my '04 996 GT3 has a Europipe exhaust installed and I was curious if there was a chance it will pass California smog as is. I've previously switched back to stock for smog tests in the past but wondered if this was needless work. Obviously, if I wouldn't have to go through the hassle of the switch and then switch back, I'd be much happier and save a bunch of time and effort. The car has very low miles and if I recall correctly, this exhaust (standard, not loud version) has the 100 cell cats.. should this help with advice. Anyone have any insight or experience they can share? Thanks and regards.

Anyone?

 

Here's a follow up and for reference... I took a chance and had the GT3 smog tested with the Europipe installed. I'm happy to report that it passed! So no more swapping out exhausts every two years. On a side note, I did run the car pretty hard just before taking it for the test in an effort to ensure everything was plenty hot. Not sure if this was required or even helped but it was fun none the less. Hope this helps someone else and saves them the time and effort the same as it will me going forward.

Thanks, if the Europipe is after the cats it makes sense that it passes. Unless they have a db restriction too.

 

Actually, the Europipe is a complete, after-headers, exhaust system including performance cats.
