Is it necessary to Jet-Hot the headers?

 

Are we ever going to quit bashing AAM? The horse is dead...Im tired of everyone throwing a bone at them...I think the point has been proven many times over?

Am I being unreasonable?

 

i really just wanna know what to expect in sound/hp difference with gutted cats and Injen TD...thats all

 

It will be raspy and loud....

 

stupid raspy, crossover is coming

 

Gutted cats will def be louder. But they are the wrong internal shape/ volume to make effecient power after they've been gutted. So I wouldn't gut a cat - just get test pipes.

 

I noticed that the headers made my exahust a bit deeper, but also made the exahust sound raspier and also a tad quieter. It was weird but the volume has deffinately lowered a bit. Under hard throttle the car has an exahust note from inside the cabin that it sorta similar to an E46 M3. its weird.

 

what kind of headers did you get?
