CA are turning into exhaust *****. Lookin for some ideas for exhaust. Ls swapped. Long tubes.

I need a quite exhaust so i dont get sent to ref. That would be the end of my iroc.
Any suggestions/solutions?

Aviator857

My exhaust on my 89 firebird is 100% factory 2000 trans am exhaust with a few modifications only on the pipes. I had to cut and re clock the cat flanges so the cats would fit without hitting the car or the engine. Then from the cats I made custom pipes into a Y just past the transmission. From there that can join either factory thridgen or in my case factory 4th gen exhaust. The LS1 is quieter than my 4 cyl CRV... though I have a magnaflow setting in a box to fix that.

The 2k air pump I mounted below the driver "battery tray" area (my battery is on passenger side) and I have the EGR etc in place. I live in a non emission checking county in GA but I wanted to see if I could build what I consider a California legal swap though obviously I've never had checked but I believe it would pass. The only thing they might not pass on my car would be the cold air intake

in san diego they being hard on exhaust on my truck haven't had any issues now if your going to a car meet that gets shut down they will ticket you which is why I don't go to any besides mature coffee and car meets
the other car meets the younger kids ruin it and do donuts burn outs etc and the cops don't really give breaks at those spots due to the ignorance and disrespect of the younger kids.
you can run some cats and a quieter muffler I used a hooker max flow with no cats and only gets loud at WOT cruising its pretty quiet that was with my ls1 swap iroc I had can look up hooker max flow 4" ls1 on youtube
for sound clip

another option is to put stock style muffler and use cut outs

Stock exhaust cutout where the cat was... done. You could throw on any 3" cutback and do the cutout if you want alittle more power and noise with the cutout closed but remember that could lead to a ticket. CA has gotten crazy with the exhaust tickets from what I've see and read. $1k ticket for aftermarket exhaust non negotiable.... insane.

With my turbo 5.3 I run a full length 3" exhaust (catback) with dynomax ultra flow SS muffler (one of the highest flowing mufflers on the market) and a cutout where the cat would be. With the cutout closed I loose a good bit of power but the car is dead quiet... so quiet I can hear the lifters and rockers ticking away but the turbo also acts like a muffler alittle. On my supercharged 5.3 I ran 1 3/4" SS long tubes and out through a 4" catback which I removed quickly and installed the 3" catback listed above and haven't gone back. Of course bc of the supercharger it was louder than a NA motor but you get the point.

Run the largest case muffler you can (dynomax ultra SS is like 19-21" case length) and throw on a eBay cutout for when you want to get rowdy.

in areas where street racing and sideshows they are more strict in cali
the entire reason that law came about was due to the increase in sideshow
activity and racing in los angeles especially south central area which you will be pull over for loud exhaust
but for majority other cities cops don't bother in been here for 14 years now

the best option is to run cutouts and freeflow quiet muffler for performance and sound

I have a 02 dodge ram for 2 years now no muffler and haven't got a ticket sitting right next to a cop
the enforcement is really dependent on the illegal activity of cars per city now I wont go driving near a car meet
getting shut down as that's sure way to get ticket for sure , I always hear that CA is ***** etc etc but that's not
really the case

with my ls1 swap I had long tubes 4 in into a hooker max flow

So you're looking for a quiet exhaust/muffler setup with Longtubes? Assuming you have the swap done already, or are set on longtubes, I'd go with a Magnaflow Muffler, Borla, OR a stock GM Muffler. Those 2 are going to be the quietest option at the end of the day. The GM Muffler will be almost stock sounding. I've done a few different 3rd Gens, so I've been thru it a few times. My personal car has a Borla Muffler, and with the plate completely closed is stock sounding as well, even with LT's and No Cats.

edit: if you have IG you can see a few sound clips I posted on my page of my car before and after the Borla Plate @thebluemagicshow

yea I agree had borla and magnaflow pretty quiet
flowmasters are horrible but I haven't tried stock muffler but would
assume would be quiet but I like the slight v8 rumble so prob only con

I forgot to say that I had no cats on mines

true but it depends on the $$$
my way around it personally is that I'm FL resident still due to active duty status
so I register car in FL

I do the same thing, I own 2 homes, the one I rent I use for registration (NJ does not have car tax), while I live in CT where I would be paying something like $1400-1700 a year in car tax on my current truck.

Zach/90\irocZ

iTrader: (6)

yea I always switch over to Florida , they go by the weight of the vehicle so bigger car more expensive and lighter less expensive and no smog is required in FL
for car just under 4k lbs I was paying like 56 bucks for year and can pay for 2 years as well , so you can save a lot on newer cars some states just go crazy with
car registration lol and Florida waives taxes for military as well so when buying car I always save couple thousand

Zach/90\irocZ

iTrader: (6)

if your that worried then leave your stock exhaust or get a factory style muffler
its kinda a no brainer you either do it or don't

How do you get around that? I was at stationed at Travis and was forced to register in CA and had to pass all their smog tests.

Zach/90\irocZ

LMAO and you fell for it lol if you want Ca plates then yea you have to

They cant force you to do nothing , cops etc always think that because your in ca you have to register your car etc but you don't your still a legal resident of the state
you joined from state taxes to driver license etc unless you want to become a ca resident its your choice and cant force you

the real issue is that people don't know and and force you to do things you don't have to do , only thing that's required to to register car on base is valid DL, Regs, Insurance
that is it

I been in California for 13 years and still have my Fl driver license and always have my cars regs. in FL once in blue moon I get pulled over for no front license plate as Florida
doesn't require a front plate and I just educate the officer and usually feels dumb and then leaves

For reg civilians that move to CA they are required to transfer to CA resident as far as plates license etc especially when you start working I forget the time frame they have 10 days or a month idk but that doesn't apply to military

Majority of law enforcement and or dmv aren't educated especially where the military population is smaller down in San Diego and camp Pendleton never have issues but up in other areas where out of state plates are not common along with military people just don't know

Nonresident Military Personnel

Any nonresident owner of a vehicle registered in a foreign state and a member of the U.S. armed forces or spouse of a member of the U.S. armed forces on active duty within this state. Any person on continuous active duty in the Air Force, Army, Navy, Marines or Coast Guard is considered military personnel. This does not include civilian personnel employed by a branch of the armed forces.
Nonresident military personnel, and both military or civilian members of NATO who are not citizens of the United States are permitted to operate a vehicle in this state with valid license plates from either:

• the individual's home state or country or
• the state or country where the individual was regularly assigned and stationed when the license plates were issued, if the following requirements are met:
  1. The license plates displayed on the vehicle are valid plates issued by a foreign jurisdiction.
  2. The vehicle registration and license plates are issued to the military person or spouse of the military person.
  3. The vehicle registration and license plates are issued by the foreign jurisdiction where the military person was last regularly assigned and stationed for duty by military orders or a jurisdiction claimed by the nonresident military person as the permanent state of residence.
  4. If the vehicle is a motor vehicle, the owner or driver has insurance.

NOTE: Military orders do not include military orders for leave, for temporary duty, or for any other assignment of any nature requiring the military person's presence outside the foreign jurisdiction where the owner was regularly assigned and stationed for duty.

This section applies to all vehicles owned by the military person or spouse except any commercial vehicle used in any business manner wherein the military person or spouse receives compensation.

Smog

Is there a nonresident military exemption from the smog inspection?

No, if the vehicle is to be registered in California, a smog inspection certification is required.

For more information on vehicle smog requirements in California click here.

Discharged Military Personnel

Any person entering California following discharge from the armed forces of the United States is exempted from registration of passenger vehicles and trailer coaches provided the vehicles have out-of-state plates and registration.

Registration becomes due when you accept gainful employment in California or become a California resident (as defined in Section 516 of the Vehicle Code) and must be paid within 20 days following that date to avoid penalties.

All I can say is that I wasn't allowed to register my car on base (We were in housing) until I passed California emissions, which I couldn't do (this was 2008-ish)

When I was at Hill AFB we had to register our vehicles in the base registry and if you were in certain counties, even if you were out of state licensed, you had to get your car smogged and the base was in one of those counties.

As I read the smog laws, if you put in a different engine, say an LS1...you have to meet emission standards for that engine. So, kinda stands to reason IF LS1 headers that have a CARB number with them and IF they would fit in your car, it should be Kosher. right?

yea they did same on marine and navy base but they got arid of that and you didn't have to pass if you was out of state regs but still need to provide a smog which wasn't even sent to the state it was a different smog because I remember it was cheaper then reg ca smog that require cert if your ca regs then yea have to pass
yea I been in since 2004 the stop doing that around that time in requiring smog because that was a big issue if I'm not mistaken in base forcing out of state cars to smog

yea now you just need regs insurance and DL they got arid of base decals as well awhile

Zach/90\irocZ

you need all emissions and needs to be in stock locations and you need to take it ref but it harder in thirdgens due to space constraints

why some people get erod everything included
