What headers are better, the shorty headers or the cattman headers for the 4th gen maxima? What are the hp comparisons between the two?

 

Depends what you want and on your setup. That answer is like your question. You really want them? Do a search and look through the forum because it has been covered and explained from start to finish plenty of times.

 

Uh oh. Better have your flame suit on.

 

Y pipes make good gains, and they're less labor intensive for installation compared to headers.
