yeah, well i did that too
i now got a normal pipe for the cat and everything is original.

i have to change it for the yearly checkup though
but i got some hp not much but some

a friend of mine said that you could feel it but i had my doubts.

maybe because the rest of my car is still original but do not expect much of it.

you get another sound too which is kinda cool.

hey.....

I have a MAGNAFLOW exhaust and a cone intake.. along with the J-spec cam.. and I can tell a difference.. so can that civic I went flying past the other night... lol.... it does help out.. I had the exhaust before the intake. and it really did help out...I suggest getting bigger pipe too.. from the cat back.. cut off the resenator too... just leave the cat and change everything else.. you can also get a bigger cat.. it says performance.. but it is just bigger... lets more air flow... but it would help too... hope this helped.. plus I got to brag a little... :)
