I just went through my second set of Magnaflow cats as well. Passenger side one started ratling, had my smog done in Santa Fe Springs for about $250 in March. Thinking about just putting in fake cats since I'm already paying it to pass. I've ran into a few roadblocks here in SoCal where they check random vehicles for smog on those moving dyno's. Not cool, haven't been put on one yet though. :)

i have been in socal my whole life...luckily never seen the rolling dynos. what cities/highways have you seen these?

We got a rolling dyno around the Stockton area.

If you guys want some proven cats that flow great and hold up.Then try picking up a set of 2500 6.0 barrel cats at the local wrecking yard.

hmmmm sounds good, but I thought the 1500 cats flow pretty good too...

EVILGMC 12-12-2009 07:59 PM

the 1500 cats do flow really well, but they are 2.5" my setup is stainless works 1.75x 3" long tubes with true dual 3 inch system.
