velocity is the key word here.

 

this is my DD and i already have a set of headers, so im not goin to change to long tubes.
from the links hurst posted, long tubes r the best for torque but lower your top speed/horsepower, un-equal length shorties give less torque but better top speed/horsepower, while equal length shorties r the happy median. which im happy with.
i could have misunderstood it, but thats my understanding. ill let hurst tell me if im right or not

and everytime u google something on this subject, all the info hurst is sayin comes up. so im goin to guess its true

 

I think someone has this backwards.

Long tubes are better for top end and horsepower.

shorties are better for low end and torque.

 

It all depends on your motor setup. if I were to put a 2.5" muffler on my lawnmower it obviously wont make optimal power, same goes for my mustang. I wouldn't stick a 1" muffler for a modded sbf. but that is just the obvious stuff. Every setup has its ideal part. Like what was said before, it all depends on how its built. but it is known that the lightly modified 5.0L mustang loves some back pressure. to give an idea to how much it likes it is when you run just mufflers and dumps, the car will feel different with just tail pipes. there are many variables and each car is different. But all in all some back pressure helps. It is just how to find the fine line that separates you from getting all your torque to robbing power.

 

Go back to the cave you fell out of. Long tubes increase both,.. torq and hp over short headers. The collector on long tubes can be tuned where shorty headers can not with out extreme modification.

look at every dyno sheet comparison. nuff said.

 

Its great to help people out but whats up with the HUGE ego? You dont have to write fucking novels about EVERY subject and bully others opinions man.

 

Opinions arent based on factual technical information. They are generally what someone 'thinks' might be right. I try to be as factual or as technically correct with any information I provide.

And where am I bullying anyone? I never make threats. I am quick to correct someone when they are wrong.

Long tubes make both,.. more HP AND TORQ than short headers. This is based on every engine dyno, tech artical ever written. Sean Hylands book, Popular HotRoddin aticles, Car Craft, MM&FF,.. you name it. This goes back to the 60's and 70's where tests were done trying different collector lengths, diameters, split designs and such. Shorty headers only work when velocity is applied to the equation. Other than slightly less restrictive tubes,.. they offer no other advantage over stock manifolds.

EGO? An ego would be me proclaiming I have something better,.. or I am in some way better. Never hear anything like that come from me either. So I dont know what your talking about. I am as humble as they come. Maybe you should read and comprehend with a clear mind before you make accusations.

Besides,.. as long as I have been here. Have you EVER known me to write up a short dissertation of anything?

the fact of the matter is, the long tubes your talking about dont come off the shelves most of us shop. so if you want to spend a couple grand on some headers i hope you have a motor worthy of them. and if you do have a motor worthy of them then yes obviously long tubes will make more power. but i stand by my statement on the short tubes being better for a mild application and being better for down low power.

 

so anyway, with my set up i need real mufflers correct?

i dont want people arguing, i know both of u lol
