s14 stock ka running without muffler?

[overb0ost]

alright well to put things short, i have a magnaflow exhaust which is probably 2-2.5" (looks tiny) and sliding has caused my muffler part to come off the pipping. but since i can just put it back on and hang the hangers back on i have the choice of having it on and off. ive experimented and it seems that WITHOUT the muffler, i feel greater throttle response. I have a stock cat and a dummy cat on the car. Now my question is, do i lose hp since i don't have much backpressure which is needed for the KA? and if so, how much? i have heard like around 3hp or so.

i'm asking this becuase im going to a drift event and im wondering if i should run the event with or without it. without it sounds so nice and mean with a deep sound.

so basically im asking is:

1) do i lose hp without the muffler on a stock KA because there isn't any backpressure, and how much? lose low end tq?

2) do i really have more throttle response or am i imagining things?

3) should i run with the muffler or without for this drift event?

thanks!

well yea..if you want even more ...you mite as well remove the cat and down pipe too..lol..i just don't know if you'd pass tech..

gonna be very loud lol

i cant remove the cat because i don't have a straight pipe to bolt on.

so would i benefit from removing the muffler? or no?

and btw, my pipping is only 2". i don't think it would be too loud. i hope i can be under 98 decibles.

haha i curretly done have an exhaust because i sold it..im waiting on one in the mail...anyways..its crazy loud..i can imagine it ever louder with out the cat...btw..its gonna be way over 98 decibles...2" piping...isn't that like stock?..really..juss keep everything on...its safer and its not much of a loss..

you're imagining things. put your muffler back on or buy a real exhaust.
if you think you feel better throttle response, then you must not be losing HP. you wont notice such a difference unless you run a plain old straight pipe.
