I didn't realize this but mac makes a long tube header for 94-97 and 99-04 so I guess headers aren't pointless for v6's anymore..... all except for my 98 anyway


merry christmas

 

Why are their no headers for the 98 model what seperates it from the 97 and 99

 

I don't know but I have had the same problem for years I think it may be a clearance issue or somthing

 

It makes no sense that the design of the engine would change from 97 to 98 i mean maybe 98 to 99 but i dont understand it and i keep hearing drastically different information from person to person

 

what have you heard

 

That it depends on the air injection port on the header or something involving the mid pipe and some tubing, I dont really know much about this stuff so its like another language to me, but i have heard from multiple sources that the only performance boost would be to change from the short headers which are stock to long tube or to port them out more?

 

it's possible that these will work http://www.ninosport.com/MAC-Longtub...2&category=100

but because it says that they don't I doubt they will

 

usually the 99-01's header will work with the 98's .....
LT's are the ONLY header choice that will net you any sort of power increase on a V6.

 

What changes from the shorty to the long tube headers?

 

if what he says is true then you best bet is these bauer http://www.ninosport.com/MAC-Longtub...2&category=100

 

they are longer

the shortys really don't flow any better than stock

 

ding ding ding ding....!!!!!!!
Beat me to it .....lol

 

No i mean performance wise what changes

 

I can't tell you but I would assume 10 or so hp

 

told you i had MAC LT Headers!!!

 

And what kind of performance boost did you get, im assuming you have a 98 v6 standard

 

It varies, I picked up about 14.7 at the wheels.
Some people I know only picked up about 10 or so, but I have never seen a LT dyno that showed less than a 6hp increase.

 

I just read on some website that in order to install the longtube headers on a 98 v6 you have to lift the engine to do so. Is that true anyone?
