i can get a used comptech 4-2-1 header for a decent price and was wondering is it worth to buy and to slap on. i did some searching and some ppl liked it and some ppl rather buy the JDM 4-1. but for me i can get the comptech for $200 as to buying the JDM 4-1 for like $400 plus a cat.
so should i go ahead and get the the comptech or spend $250 more for the
JDM 4-1?
i daily drive my car and only have an intake.

 

its depends on what kind of power you want to make. the comptech should flow better than stock.. but not as well as the JDM 4-1..
