I currently have a K&N filter with the air box mod, SLP shorty headers, and a SLP cat back exhaust. I still have my stock downpipe and cat. Will i gain more performance by taking it off? Some people say yes, some people say not really. I also heard i could lose a little boost because theres no back pressure.

 

lose boost because of no back pressure?

uh no.. take it off you wont pass smog or anything like that.

but im just wondering... whered you put your other header?

 

no you won't notice any difference except less bacpressure,flames and rasp

other then that performance wise dosen't matter.....althought i didn't loose any boost when i did it..and gained some up top from whre i lost it down low.

 

Your talking about that rasp my exhaust has under boost, i hate that.
