Sorry to ask a question that may have been asked but since the search feature isn't currently up bear with me.

How is the Cattman Header System on custommaxima.com going to compare to just getting a warp y-pipe? I'm not really asking whether it's worth the extra $$ so much as what kind of difference in performance you're going to see between the two.

 

with the cattman system you're replacing the exhaust manifolds as well as the y-pipe were with warpspeed you're just replacing the y-pipe. with the new exhaust manifold you get with the cattman system you have a more free flowing system so more power.

 

unless you're going for that last possible HP out of your engine, there is no real benefit of the cattman headers over a y-pipe. out exhaust manifolds flow pretty good, and the difference between the y-pipe and the headears is about 5hp. headers do look nice, and apparently sound pretty good, but they will require major install time (4-6 hours at least).

 

Pros of cattman headers

* 5-10 hp over a y depending on your mods
* beautiful sound versus not so good
* lighter than y & stock manifold (dont need heatshield either)
* increased/enhanced driving experience (entering true sports sedan arena)
* more eye candy under the hood

Transforms the maxima into something much different

if you can have either, and price is not an issue, this is a no brainer !

My Vote: cattman headers
