i know either one will only give like maybe 2-3whp at the most but which do you think would be better???

 

Are you running a manual or auto transmission? From what I heard the headers don't help out much with an auto tranny. Even if it did I would personally get the catback for better airflow and better sound for the xA.

 

With out the exhaust the headers won't do much ... I would get the exhaust first and then get the headers!

 

Word!

 

SideNote Check out the Strup Performance Headers and Exhaust ... they work awsome together and there is a noticable gain in performance with out being loud and ricy!

 

plus, if you get the exhaust, you get the added benefit of sounding good

 

well be patient, b/c unless your gettin a custom cat-back done there are no catbacks available for the xA yet... unless u count the magnaflow one but that isnt comin out for a while.
OR, you can be me, and buy a header then patiently twiddle ur fingers while an ingenious company comes up w/ a catback
