Headers: Long vs Short?

well i personally like the long tubes but both have there ups and downs. long tubes give you a noticably larger gain in hp and tq however they are normally not street legal they wont pass smog. I live in cali so i put the gibson shorty headers on i love them and they pass smog with no problem. And i still noticed a decent gain in hp and tq.

 

google it!

 

shortys make more tq down in the lower rpms, long tubes make more HP in the upper rpms. you gotta decide where yer motors operates the most..

 

so lets say you go with the short tubes and gain low end power does it necessarily decrease upper rpm power? tacos have good power already i think, for a truck, would shorties give low end power that then noticeably drops off when entering higher rpms???

 

no, what i mean is short tube headers generally make more power than STOCK with the biggest gains in the lower rpm range, long tubes will make more power than stock with the most coming in the upper range, more than short tubes. short tubes usually make more torque than long tubes. but then i base my experiance on honda vtec b motors.

 

I googled the difference between short and long tube headers and I found out that long tubes are better for low end rpm while the short tubes are for higher rpm.
here is one of the sites I found the info on;

I am trying to figure out the best step up for my truck. This is the 2nd time I have to change the manifolds on my truck. The first time was under warranty still. I was always told shorties didnt really do anything. I won't be supercharging the truck or anything like that. I liked the long tube idea with the gains mostly in the low end.

 

Keep in mind that because the 1gr is a V6, Tri-Y option and its benefits are not available.

Plus, the cost of shorties will likely be more than the cost of long tubes or equal, after you factor in the cost to have your cats welded back on. Not to discredit those that want to keep emissions standards. You just have to pay more.

Also, here is a good link. http://www.tacomaworld.com/forum/performance-tuning/229882-n-power-gains-dynos-w-mods.html

If we can get dyno's of more members and their specific mods, it will create an even better picture.

 

Ok, now if I do short tubes I need to find aftermarket cats to replace the ones on the manifolds. My check engine light is on because of the cats throughing the O2 off. What cats can I get that are decent and don't cost big money?

 

Im pretty sure you can re-use your original cats. Not 100% though

 

Damn phone and only showing open post lol

 

I will check them out. I have a cat back exhaust from magnaflow. Has anyone done the shorties with aftermarket cats? If so post some pictures if you can
