I was wondering witch helped more iam on a bit on a buget and cant do bolth and the same time after buying K04s and all piping and finding out that my problim was just a torn TBB so iam going to wateto put in the K04s untillI have at least a stage 2 car

 

And what should i do with the intake(k&n or just keep putting in clean stock paper filters)or buy one

 

Cat back, it really helps in the upper end. IC will do almost nothing on a stock car.

 

Ok iam going to buy one is there one. Is there a cat back that is better performance wise
and what is the best thing thatto do with the intake

 

Get the one that sounds the best to you, they are all about the same performance wise.

Do the Darintake, & a panel filter, if you feel like spending the $$ get the AWE S-flow.
