anybody have this one..?
they look like an easy upgrade , but, do they really do anything.?...:w
 
I wouldn't bother with shorty headers.
 
didnt think so either....thanx

I put a set of full length Hooker headers on my '78. It made a world of a difference. I'd consider full length duals w/ an X pipe, high flow cats, and other goodies that help the engine exhale.

Not sure what is CARB approved and what is not- I'm sure that will be a consideration for you because of your state.

as long as the cats are working it doesnt matter what kind of pipes you have ..its all about the gas comming out...they stick a probe up your exhaust pipe and run the car on kind of a dyno at different speeds and measure everything.comming out.im clueless as to whats what but i know if you pay cash and give a big tip the nimbers change....
why the X pipe and not true duels with a H equalizer.?
 
X pipes are better, better flow because of savaging effect. An h pipe merely equalizes the pressure between banks. I'm running stock manifolds/cats, x-pipe with muffler eliminators. Not as loud as you would think. Cats do a lot of muffling. X pipe also cuts resonace and interior noise big time. Way better than the stock resonator does. Much deeper sound too...I love it. Pain the butt to install however.

Shorties dont get you much, the stock LT1 manifold flow very well. Long tubes on the other hand, yeah buddy!!!!

i was for sure thinking the resonator was history ill look at the x thing..but eliminate all three mufflers.?
can it be not obnoxious..do you have a youtube of it.?
:w
 
I WILL have a youtube of my car soon. Next couple weeks when my brother is home, he has got the digital cam. Search youtube and some guys are running similar setups. Mellow at idle. Nasty above 2500rpm. I love it and I cruise around all the time. Put it this way, my buddy has a 90 Mustang GT (nice car) with headers, no cats, h pipe and a set of 40 series flowmasters, and his car is WAY louder than mine at idle and anywhere in the RPM range.

This will be similar to mine, he is running an h pipe however.

Sweet, sounding, very close to mine, especially the idle.

If you can afford it, I like the Corsa system myself.

If you decide to do muffler eliminators in the back, I got mine from Corvette Central do the x-pipe or else you WILL hate the resonance that the stock resonator DOESN'T get rid of .

FYI, stock resonator is nothing more than straight pipe inside a box, with perforations inside the pipe on either side. No crossover inside the stock resonator. I assume there is some sort of packing on the other side of the perforations?

Obnoxious, it is not at least to me, but I'm 21 I like it kind of loud but it defintly isnt STUPID loud like open headers or a side pipe equipped Big Block 427 Vette. Like I said the cats do a lot of MUFFLING.
 
Okay guys... this is probably going to sound dumb, but I don't have much in the way of technical knowledge and I find your conversation interesting.

As I understand it, headers, x-pipe, hi-flow cats, etc. are beneficial because they move the exhaust gases out faster, thus reducing back pressure. Increasing air induction on the front end and increasing exhaust flow at the rear equals increased power ie horsepower, correct? Is it increased power or increased torque? See, I told you it would sound dumb. ;)

So, other than the obvious, :L what's the difference in short headers versus long tube headers, performance-wise, that is?

Thanks for your patience.

Anything you do to cause more air flow to an otherwise stock motor will move the power band higher up the rpm scale. This will result in a decrease in lower end torque.
To increase exhaust flow you want the exhaust to be as smooth as possible. The less conections in the system the better. Anything that could cause turbulence will slow down the flow. That is why long tube headers are better. Shortys will not be much different than stock manifolds.

it wont work in mississippi....

lol, seriously..
your engine is an air pump the more you can pump the better you will like it ( did that sound right,?)
so its both..with smaller tube headders you will get more torque which is what you want for a daily driver...
but stock is still stock and can always be improved upon..
:cool

short tube headers are just stock manifolds made from tubeing..not enough gain to notice..
long tube will scavenge the gas and cause a lot more out = more in....dig.?:cool
 
To sum it up, any internal combustion engine is basically an air pump. The more air you can get in the more power you can make. AKA. what we in the know like to call "Volumetric Efficiency." Turbos and Superchargers increase Vol. Eff. dramatically that is why your boys Honda 4 with 30psi of boost can make 500hp. Anything beyond 100% Vol. Eff. is only possible with boost.

To explain this further, when your intake valve opens and the piston is going down it creates a vacumn in the cylinder which air rushes into at 14.7psi (1 atmoshpehere), the amount of air is dependent on the flow of the heads, RPM, Camshaft-Lift, Duration, Overlap,etc...if you are getting lots of air in you need to get it out. Hence, a exhaust system that scavenges the gases out will help Horsepower and torque.

How much HP you gain or lose and the same with torque is dependent on how you build your engine. Any moron can build a big HP motor, but it is the guy that can get big HP number while maintianing low end and middle range torque aka Drivability that is the REAL engine builder.

Without further making this more complex, I'll explain the REAL DEAL and my PERSONAL OPINION on making HP.

Whatever intake, heads, cam, exhaust, etc...you choose it all HAS TO WORK together. You can take a bone stock LT1 and stick a big nasty cc306 cam in it, but you wont reach the real potential of that cam. WHY, not enough head, intake, or exhaust to accommodate the Air Flow potential of that camshaft.

Whatever you do beyond a free flowing exhaust or cold air intake...GET A TUNE!!! Your engine cannot reach FULL POTENTIAL without a TUNE!!!

I can go on but I don't want to lose anybody. Not that I'm insulting you, but I'm digressing into pretty technical stuff, here. Hopefully, this is clear and we are just scratching the surface. For the record I'm no expert in H.O. engine building but I am a auto. tech. by profession and understand how engines operate.
 

He has a cam in that so that WILL change the sound quite a bit. I like it too, but not rummbly enough for me.

Sounds great at ldle, but to quiet and tinny for me when he revs it. I want to sound like a open header muscle car when I rev it with a cam like that.

As it has been said a thousand times, Exhaust sound is PURELY subjective, everybody like opinions will have a different one.

thanx for the tip

Long Tubes

Here's the set up on mine. Kooks long tubes, x-pipe and high flow cats. After the installation I had the car dyno tuned......big difference.
