i was just wondering about how much horsepower and torque i would gain from installing the banks torque tube header on my 4.0L?

 

search for the APN header. its the same thing, just not as blingy. you really wont notice much unless you do it along with a hi-flow cat and muffler

 

Ebay header i bought works awesome and is as big as all the rest for less than a 1/3 of th cost...I made a thread about it not to long ago.

 

the 2000 and 2001 are different then the rest i have only see the banks one for these years

 

if you open up the exhaust, you should open up the intake to get the best out of it.
go with a cold air intake and larger throttle body/spacer.

 

Hey i was wondering what kind of headers those were because i am looking for some right now?

 

Why, the OE intake is not restrictive by any means

 

i have the banks header and it bolted right up in my 96'

to the OP its a great product with a lifetime warranty and good customer service. but there are other headers out there for cheaper. i knew the banks name from diesel products and i wanted to try them out. i feel like the header added a little bit of pep it changed the exhaust note alot too for the better but anything is better then the old cracked manifolds.

nvm just noticed the date on this thread its old the OP is probably like a hundred years old by now
