Street legal mods from Nismo?

[H2O_Doc]

The only people running around without cats are either driving antiques or modified vehicles, which are the extreme minority. I highly, HIGHLY doubt we're "significantly responsible" for ANY mess.

There's no misrepresentation in the RPM Act. It's all based directly off of what the EPA has said or done.

Well, you are correct that its not just running catless. It is also due to SOME tuners running cars in a manner that increases hydrocarbon and other emissions. A small proportion of cars can have a measurable effect on air quality. Yes, measurable.

I thank EPA for the clean air I breath, being old enough to remember the chocking smog of LA back in the day. All the folks running around with catless exhaust are significantly responsible for this mess. And, while I appreciate SEMA in general, they are guilty of gross misrepresentations of much what is going on and why.

You don’t have the right to drive catless on public roads or tune your car in ways that cause it to exceed NAAQS.

LA, to this day, still has horrible air quality.

Maybe the politicians and elites jetting around are having a much bigger impact on AQ than us plebs?

Even if that were true, we'd be more than offset by the amount of hybrids and electrics on the road.

It's not like tuners are purposely trying to do that, it just comes with the high performance ICE territory.

Again, there's no chance the small community of enthusiasts are having any kind of significant (hell, maybe even ANY) impact on the environment. Hell, half of us don't even drive our cars more than a couple times a week, if that.

Sounds

Finally getting a chance to watch this and you are not kidding. That thing RIPS

Too bad bad it'll run 15-17k for the Alpha 600 package......I hope this is another "Dinan" situation where you can DIY for much less.

I've heard of many enthusiasts who did catless tuning and eventually had cats reinstalled because they didn't like the funky exhaust smell.

Most modified cars with functioning cats are going to run very clean whilst running stoichiometric closed loop.
Maybe during WOT runs they'll be out of spec, but that's really insignificant, how often does that occur?

The solution is high-flow cats - however, I'm not sure if any high flows are even legal anymore. When I was getting into mods for my Camaro (about 9 years ago now), Kooks Green Cats did very well in places like CA or with anyone that didn't want to have their car tuned to avoid a CEL.

High flow cats on the VR30 may eliminate the need for a tune (and probably won't result in a CEL), but I doubt they're legal in CA, especially with the complimentary sound and smog checks they're getting

Yup. not legal in CA. I swear if it wasn't for the bomb weed and Coachella, people would've moved out in droves.

And it's not exactly something any weekend warrior could do. Motor needs to come out to swap out to the Pure turbos. I'd need a lift for that, wouldn't trust a hoist.

You young'uns have no idea what the environment was like back in the 70's.

I don't wanna go back there...

The cars and everything else is completely different now than it was in the 70s. Changing something on your car is now a big deal because Uncle Sam has to figure out how to get more money out of people. And what’s really funny is where was that picture taken because it doesn’t look like California to me.

I think you might wanna do a lot more reading before you jump on the bandwagon of the EPA. Just my opinion. You keep yours and I’ll keep mine

The ONLY thing you cannot change is anything which would alter emissions controls. It's been that way for decades.

And, California is not the only area in the world to experience toxic air in the past.

I don't think high flows are legal anywhere IIRC. Last time I checked it was illegal to tamper with cats unless they needed replacement.

Do you know how many things alter emissions? Again, that's the entire point of the RPM Act. Everything from exhausts to turbos and engine internals were targeted.

As someone who has been to Manila multiple times in the 90's and early '00's, I can definitely attest to this! Luckily, the last few times there I noticed it is much improved.
