What if you just left the stock exhaust manifold and got rid of that awfully small tubing that comes stock (what is that, like 1.5") and beefed it up to like 2.25" or 2.5 ?
Would that be a good way to go ?
Will this do anything for the car or just drain my pocket ?
I would be doing the rest of the car in 2.25 as well, but what do you think....
Will I be accomplishing anything this way ?
it will be better than stock but not as good as a system with a header...
really though they are not that expensive

From what I've seen and heard, anything less than a full exhaust really won't do much noticeable for power. A header isn't really that expensive, relatively speaking of course and personally I'd do it all at once. Also, I believe stock piping is 1.75".

Bare minimum do the pacesetter header....

extra flow capacity won't help if you can't get extra flow...
header organizes exhaust pulses, and increases cylinder scavenging.
larger diameter piping on the rest of the car is just going to make more noise, not more power.
It's just that here in Ca. specifically Riverside/San Bernardino County, they have random road side smog checks where they just rip you to pieces for "non-legal" exhaust.. I have all the technology to fab a nice header, and I have a friend that has a new 2.2 header for my car it's just not C.A.R.B. legal... And the other problem, even when you have c.a.r.b. numbers on your sh*t the police still ticket you for having "modified exhaust, intake, suspension (you name it)" and now they have an impound now, talk later policy where they will crush your car into a cube if they "think" you are gonna race your car...
Then you probably shouldn't be touching the more visible part of your exhaust. If anything get a header and leave the rest alone if you're worried about the cops hassling you. As far as performance goes though, I'll parrot PJ. Do it all or it's pointless.

I know the pacesetter 2.2 eco header is 50 state carb legal....I have the LSJ header (2.0 supercharged) now in cali that would not be legal. But i cant see why they would ticket you if the CARB number is stamped right on the product..
my exhaust looks stock, you dont need a can for a muffler.. get the magnaflow 4x8" muffler, that looks stock.

I have a stockish looking setup on there now, my problem is, once they pop the hood... Then what do I do ?
If it doesn't have that tag I'm EFFED..
My whole purpose is to suck as much HP out of it as I can, I would like it to be fairly quiet until I step on it, then you need to think the gates of hell just flew open... HA HA J/K.... But I don't like that ricey, fart box sound like the honda's make when you just throw on a 5" can and call it a day. that bugs the hell out of me.
why would you pop your hood, as far as i know they cant force you to open your hood or search your car just because..

They can't, but then they can impound it for probably cause...its some
, but Cali has some EFFed up laws....been there done that...Just get the 50 state legal 2.2 Eco header From PaceSetter, and you will love it...I PROMISE!
BTW, it is even against the law to replace ur cat converter in Cali unless a qualified emissions shop deems it is not functioning correctly...

Come to Cali and try telling a cop that.
In CA a cop can pop your hood without cause or reasonable doubt. Searching the vehicle other than under the hood however is different.
Get the PS header, mate it to your OEM cat, and do whatever catback you like. 100% legal in CA as long as the CB is under 95 dB. SB cops are dicks, I had a SB Sheriff hassling me in the parking lot of Cali Speedway at a NASCAR race. I talked myself out of having my hood popped.

the man speaks the truth. he would know about as well as anyone, with that turbo he has...lol..
Chad do u know if that cat converter law is around still in Cali? just curious...
Yup, very few aftermarket cats are CARB legal, and as far as I know there isn't one specifically for the J Body that is legal.
Ca. has alot of shi**y laws but yeah, I was probably just gonna leave the stock cat in place and add a resonator behind it and go 2.25 all the way to the muffler.
I think it's time I chime-in here...
Shee Man's car has a LN2/2.2L, and the factory exhaust found behind them is 1-7/8"dia. All LN2's have it, including the one's placed in S-trucks. The simplest exhaust upgrade that can't really be noticed is to install a 2" system with a Walker Dynomax, full length from the cat-back. Even if you add a Cherry Bomb midway between the cat & the muffler (Keep it the same size now!), I seriously doubt the fuzz will give you heat about it. In fact, an interesting note is that for some bizarre reason the extention-pipe fould on my '94 LN2'd S-truck is 2-1/4", and then it goes back to 1-7/8" after that. Goofy, huh? Anyways, if that's the case with the LN2'd J-cars, then that'd be the way to go for the glass-pack acting as a resonator & all between the cat's outlet & the muffler's inlet, and then have 2" going from the engine to the cat & from the muffler to the end.
As for if the CHiPs gettingt you down, blame the greedy, idiotic A-holes in Hollywood that produced that damn import-racing movie that got all the less-wise kids goin' crazy & street-racing themselves, forcing the local enforcement to rack-down harder than before. It seems most of the average street-scene folk you saw at a scene before the movie was released knew what the hell they were doing & talking about than afterwards. Even the newbies to it had more sense. But now...
Go beyond the "bolt-on".
see... the stock stuff is just small. but what differance would 2" make over the 1 7/8 ???

heh damn, that is pretty gay. i would say my hood pop latch doesnt work and show him the switch doesnt work and have a hidden switch somewhere else
damn cops hassle you when you aint doin anything wrong but when you need them, where are they eh?

Now with california, could you cheet the system by keeping the stock cat but enlarging the pipe to 2.25"??? it's still the same cat it's just a larger pipe thats going in and out of it. It's not really changing the emissions of the car any either. I have thought about making a 2.25" pipe that comes off of my stock exhaust manifold as well. It would prolly be in your better interest though to just get the pacesetter since it's 50 state legal.

why is it called a header anyway.
Why have you never made a worth a crap post on this forum?
Somethings just can't be explained.

1hp? maybe 2? its not worth the effort.
leave the exhaust alone, or move to another state and do it all.
also, the only way you'll see maximum yield from ANY mod on a jbody is to have it tuned via HPT or run a stand alone. Our ECUs aren't adaptive.. meaning they assume that airflow through the engine is the same.. so mechanical changes WON'T be "learned" by the ecu.
but I reiterate.. full exhaust, or don't waste your time. Money is better spent elsewhere.. like moving to a state other than CA.
Not to mention how the cripling lack of Mass Air-Flow Sensor installation by the factory don't help the ECM in sensing changes, either. But that's more of the same.
Go beyond the "bolt-on".
Oh, it's more than just using the stock cat, I've found. The pipe to the cat is still 1-7/8", but like I said about how the enlarged area inside the cat makes it act like a pressure-wave chamber, the down-pipe acts like a tuned collector to it, allowing the engine to be properly scavenged of the the exhaust gases at a certain RPM, much like putting a flared collector-extention on a header. As for the 2.25" pipe after it, that's a bit of mystery to me. I do know that on the system I have (Which had the catalytic-convertor replaced) the cat installed was one of a 2.25" inlet & outlet. I guess the 2.25" extention pipe from the cat to the muffler, follwed by the 1-7/8" tailpipe is just the factory's cheap way of trying to contain the noise by allowing gases to build-up in the muffler while still keeping the exhaust properly tuned. Goofy, huh?
