i have a question for you guys i just got and installed a set of equal lenght shorty headers..the sound good, it makes the car have a throatier sound but are these good for high end or low end or both??

 

Im pretty sure they free up the power all across the board.

 

well you didn't say what size the primary tubes are....but they help mid range power

 

They're more for low end to mid range. If you want high power you'll need long tube.

 

you will never realize the difference in the long tubes and shorties unless you pulling about 450 @ the wheel

 

agree with that other "old man" vfast on this one! I'm running equal lenght MAC 1-5/8" shorty headers and they work fine with my basically stock engine and were also real good on the street when I still drove it on the street. a recent 5.0 mag did a dyno test of different types and sizes of headers on a 347 stroker and the long tubes were only 5 HP better than the shorties at 5,500 rpm, so make it easy on yourself and go with the shorties.

 

I was reading a magazine @ the bookstore on this on a 90 5.0. The equal gave more hp from low to mid-range. & the unequal gave more hp than the equals in high rpm's. Long tubes beat both of them in low, mid, & high range. It showed as much as 8hp increase over both the others.

 

putting equal length long tubes on a stang is not worth 8 hp it is a pain, long tubes are a breeze but long tube equal length are almost impossible, not even if they were free would i install them.

 

ROFL. Yea, I heard they were a b**** to install.

 

Your tellin me i did them and i went threw all hell but i got them on and they feel get and sound great. They seem to work good with my Offroad H and Flowmasters. I had Mac Long Tube so idk if people buy those much. I think they look good and they seemed good but they were like putting regular exasht in a little spot in the engine bay. Man oh man it was not really easy but there done and im happy.
