Removing cat and stripping trunk?

[jboyce]

Someone said something about removing my CAT for a free modification. How would i go about this...any DIY?

Also something about removing stuff from the trunk for sound deadening or some crap.

Anyone know more information on either of these statements?

Yes. You can remove your cat from your exhaust system. I recommend using a "test pipe" if you do not want to run a catilytic converter. Or you can "gut" the cat. Be aware, when utilizing the test pipe, or gutted cat your exhaust tone will increase, and you will loose some low end torque, not a lot though, and gain more high end hp, also not a lot. As far as removing items from the trunk, you can take out the spare tire, trim panels, and carpet. This will shed a few pounds off of your car.

actually i have seen peeps use paint scrapers that u use on houses to remove paint, get a shapr one from home depot they work wonders. also when scraping that shit off heat up the scraper untill so hot it almost turns red. that will help a lot. theres a lot of that shit. use a torch to heat of the scraper. if u have an old dull scraper at home sharpen it with grinder. and if u dont know what the sound deadener is its that shit that looks like tar. should be painted over with the samecolor of your car but ya never know. good luck.

How do i remove the converter, do i need to weld anything? can anyone write up a DIY or link me to one...what should i buy to do it and all that. i wanna do it.

How much does the trunk tar weigh, and would it like affect sound or cold/heat coming into the car a lot?

[91accord4door]

the shit weighs a lot i am not sure of the total weight but if u get it all out its probably 20+ pounds. and it will effect the noise a bit but not the cold. and as far as removing the cat its just 6 bolts. if its the stock cat than there probably rusted to shit, i got mine off and gutted mine and when i put it back on i used stainless bolts/nuts. hasnt rusted. if your just gutting it just remove 6 bolts/nuts, remove cat, bang out all the insides, reinstall cat. its that easy. just use lube on the bolts/nuts and you mayhave to heat up the bolts to remove them. mine were so bad u couldnt even tell there were bolts in because they were rusted over.good luck.

oh ya the tar stuff is also under the carpet in the car, its under the backseat etc. thats why its atleast 20+ pounds. the only thing it will effect is maybe you';ll have a little bit more noise but not much.

sweet, i'll do the cat tonight. and as far as the the sound thingin the trunk...what sound does it change, or make louder etc..if i take it out? exaust sound?

[91accord4door]

well mostly you might here more exhaust sounds, ,my friend did this but he said he didnt notice a differeance. so its only something to keep in mind. if anything youll get more sounds coming from the trunk since that were the tail pipe is. nothing to worry about. and when u take off your cat or attempt too dont be surprised if your cats bolts are rusted so bad to the nuts that u cant even see the nuts. they get rusted so bad that they actually bond together. if that happens break out the sawzall/cutting wheels.

can you pass emissions without a cat? or do you cheaters just put the old cat back on just for the MVD and swap back when you get home?

My secret is that my car is registered in a no smog county...


But I have a friend that works at a little smog check place and we were sitting around bored one day and tested our cars just to see the readings and if they'd pass...

neither one of us did...by alot...

His car IS registered in a smog county though but he IS the ultimate hookup in that dept...

I won't mention his name for fear that I might need to use his under the table services one day...pretty good deal if you ask me... He charges $50 if you know you won't pass then $30 every year you come back to him... been doing it for years...

I'm glad we're so environment conscience!

I rolled my car up on those two wheel thingies to get under the car. The bolts were impossible to get off, and i have no money to buy solvent solutions or whatever to get them off. I tried hitting them with my wrench, but brute force only left me with dirt in my eye. So i was out of time, and decided i'll just try it later. even though i want this done NOW =(

[stroiker]

not to sound synical but if you dont have money to buy solvent($5) to loosen the bolts then how do u expect to put a test pipe on(+$20)
it just goes to show that almost any mod people do to there cars is gonna cost some money. wish there were actual free mods
