Hey Guys I was wondering if I could get Headers installed at the Dealership ? im thinking of going with JBA headers. Oh and what warranty would this effect ? Im thinking it would be the exhaust warranty

 

These headers go on quite easy seeing as they are shorties man if you can save a bunch of money and do it yourself.Some nice deals around on them.I dunno about the warranty or if they would do it.My dealership gets thier panties all bunched up if i ask them about any of that.

 

haha....for real. my dealership acts the same way.

 

im still wondering what gains would a v6 4.0 see with short headers. LS1 with short headers show practically no gains 5rwhp at best. Having said that why not do long tube headers with high flow cats instead of short headers. I think that long tubes will show better gains than shorties, but dont have any dyno graph to back that up. Have anyone done long tubes headers in a 4.0?

 

Oh,hey,stainless works just said today they have lt headers now for the 4.0

Makes worth considering as i bet they are high quality and MAY produce a nice sound over the macs.
