95 exhaust upgrade, ca legal?
Hi I just got a 95 Maxima with an Injen cold air intake, H&R coil springs, and a Progress rear sway bar. Runs great! but I want more.... I hear that a y-pipe upgrade is a good bang-for-the-buck upgrade, but I live in California where regulations on smog and street-legality are rough. Can I upgrade without failing smog? And what size pipe should I get? For me, performance> noise, I actually like having a sleeper.

A ypipe only eliminates the precats. Just be sure to bring your car to the smog shop nice and hot. Go for a 20 minute drive before arriving. You'll pass emissions no problem. Just don't go to a shop that will do a very thorough visual inspection.(99% of shops don't look under the car)
All ypipes are about 2.5". Lookup Warpspeed or keep your eyes open in the classifieds.

Ok, that's good to know, now I just need to find a good manufacturer (Warpspeed doesn't ship to California :/ ) One more question: what's the difference between a cat-back exhaust and a y-pipe exhaust? I hear people talk about both but I don't really know the specific details.

Right. Anything that deals with pollution has to be done by a licensed repair shop.
Unless it got changed in the last year or so, auto parts stores aren't allowed to read check engine codes. You have to go to a licensed repair shop for that and it isn't necessarily a free service.

We typically try to avoid shipping to California because the pre-cats are eliminated, we prefer to ship to an adjacent state where they are a little more legal. Of course if you tell us it is for off-road use only..................
We recently had to change flange suppliers because our current supplier quit making them for the 1989-2000 Feds, we had one of our other vendors make up a batch of laser cut flanges and we expect them around the 26th of this month. They will ship a little faster at that point.

Thank you everyone for all the help, I appreciate it.
Now that you mention it, I actually need this for off road use only!
One last question: will switching to a high flow cat cause smog issues? I'm assuming it does

You'll still pass with a high flow cat. Not by much, but you'll still pass.

this is a very informative thread because I was wondering the same thing about exhausts. I got lucky in passing emissions in Cali since Im from NY. I wanted to eventually do some work but wasnt sure on how to go about it. I just look for threads and read
