Hey guys i was wondering if i put headers on my wrx it i would throw a cel,my current upgrades are Perrin uppipe,Cobb DP,DCSports CBE and K&N short ram intake.Also is there anything i should know about.

 

well i'm sure you know the difference between equal and unequal length header so i wont go into it(unless you ask). Anyways headers on a 2.0 will cause you to loose a little low end and give you some more top end power. If you get aftermarket unequal length headers you will still have the boxer rumble but it will be less dramatic.(smooth it out a little). and no you wont throw a cel with a header installed. what type of engine management are you running? you might also want to look into ported oem manifolds.....

 

I forgot to add Cobb AP as my engine management,i would look into porting my heads but im in a military town and local foks try to rip you off with over priced jobs and ****edup work,all so the only people i trust with my car is my service guy at the dealer a.k.a mike,and yes i know the diffrence between the equal and unequal length headers.Thanks for the help bro.
