Ive been looking into headers for my 2003 nissan 350z, and I was looking into the more budget end of the spectrum, I dont want pure trash, but something that will be OK in terms of fitment, and still allow me to be able to run the ART pipes

long story short, I was looking into ISR Shorty headers, anyone have thoughts on them, or is it a hard no? or whats the consensus on them... and if no, then what $5-600 or so headers would you suggest?

 

Only shorty headers I'd use are Tomei.
