Cat question

[Guest Anonymous]

I have a 1977 280z with a 350 in Texas. I have to finish the exhaust soon and was wondering if there are any requirements on the number of cats, mufflers, etc. I need to put on the car. Dumb question, better safe than sorry. Thank you.

Depends on where you live as many of the larger metro areas have smog testing and visual inspections. That will be your case. Around here, depends on how lazy the state inpspecter is . What a joke that is, anyhow. Before I went to antique plates on my Camaro I used to get the annual inspection. Guy spends 10 minutes looking at wiper blades then checks brake fluid. Doesn't notice that their is a fuel leak. He puts sticker on car, and I drive around corner, get out leatherman tool and tighten up clamp. But he was SURE my wipers were in good shape, after all, this is TX, 270+ days of sunshine every year. State inspection is just another tax IMO.

In our area if your car came with a cat you have to have it on the car. But since most Z did not come with one dont worry about it. Also since your car is a 77 you only need to do a safety inspection, no emissions needed. Any car 25 years old or older (78-older77,76,75 etc...) requires only the safety. 2-24 years requires emissions testing. 95 and below requires the treadmill and 96 and above with the OBDII system just requires them to plug into your car and see if all is well. Why they dont check the actual emissions on the OBDII i dont know. (O2 sims can easily be installed) If your worried that they will check underneath your car for a cat, you have a better chance winning the Texas Lottery. Here's a link for more info.
