Texas yearly emissions check vs exhaust mods
2002 WRX. I live in Fort Worth and I want to do the typical cat-less up-pipe and TBE but am concerned about passing the yearly TX inspection/emissions. If I keep just the stock down-pipe and cat will I pass emissions? I read on the TX DPS site that on newer cars they just check the OBDII to see if there are any emissions equipment problems. Does that mean they don't actually measure the exhaust emissions (sniffer test)?
On a related note. My car is bone stock so will I see much difference by gutting up-pipe and removing the third cat but keeping the stock down-pipe with cat? Or do I need to loose the DP cat too?

I know that the cat in the uppipe is put in there specifically to pass on cold start ups..so taking that out and still passing smog shouldn't be a problem. As for removing one in the dp and still passig? Better cross your fingers..
