Hey,

I just got my apexi n1 for my 2000 civic ex, and im trying to install it. well, trying to uninstall my stock exhuast lol. i got the muffler off but now im trying to get the cat off, along with the resonator.

there are 3 rusted bolts at the beginning of the cat:


there are 2 bolts with springs located at the end of the cat (facing the back of the car):


and then there are 2 bolts on the other side:


what the hell do i do? everything is pretty much rusted. any tips? ideas? anything at all? i used pb blaster on everything, but i dont wanna break something that will cost me alot

 

Sawzall. It'll get that bugger out in five seconds. :chuckles:


Really, there itsn't much you can do here but cut or try to break the bolts.

 

i could just try and unscrew the 3 bolts at the beginning of the cat, but at the back, there isnt a nut or anything, its pretty much flat, except for a minor bump at the end. can i just try and unscrew these? or are the welded in, i cant tell. my muffler is off, so itd be kinda hard to drive somewhere. any other suggestions?

 

Just cut and replace...either that or wait till you get a header And just drop out the whole thing and replace...heheh..

 

Wait, you're asking what to do and you haven't even put a wrench to them yet? Duh, first step. If that doesn't work, cut, brake, and/or replace.

 

oh no, trust me, ive put a wrench to it! im afraid that if i go in and cut off the nut on the one side, then the screw will be stuck on the inside and then ill hafta buy a new cat conv.

 

If you cut/grind the nut off, it will fall apart like you want it to.

 

hmmm, alright, well i think im going to try and cut it off. wish me luck guys!

also, im trying to take the silencer out, and damn is that thing in there good... it looks like they put sticky stuff on the inside, between the silencer and actual muffler tip. any tips on how to get it out? i took off the bolt, but it wont budge

 

Go to the parts store and pickup a wire brush. Scrub those 3 bolts on the back of the cat and get all that crap off of them. Find a deepwell socket that just barely doesnt' fit over the bolts (13mm will probably do it), settle it so it's lined up right and hammer that ****er on there. Put a breaker bar on (I'm assuming everything is soaked in PB blaster too) and just crank them off. Your best bet is go find some new nuts before you start too. That's what I did with mine, if you loosen the rubber hanger down from the cat and lay the B-pipe down on the ground (with the front jacked up) and slide it to one side, you can get a wrench on the top bolt.

 

well... ive decided that im just gunna hafta cut the shit outta them.

anyone know how to get the silencer out? its in there really tight! anyone got any tips?
