hey guys should i go with no cat or withi the cat for my dp?

 

basically the ONLY positive for keeping the cat is that its legal.
and since your in alberta....we can kinda get away with it really easily.

 

haha u guys r lucky

 

is a catless illegal in the states?

 

yea i believe i ordered my with the magnaflow cat

 

yeah but it doesn't really matter if you live in a state where they odn't have emissions checks

 

its pretty much illegal everywhere.

but some places you can just get away with it alot easier.
Some places in the states are emissions *****...and have to be checked all the time etc...

 

I gutted my cat....it was very easy, I just use a long bar to smash the insides out....took about 1hr altogether.... didnt cost me anything....it never made it that much louder, maybe abit....changed the tone a little bit and gained abit on the topend.... When I get a better power adder(blower swap or turbo swap) then I will replace all my exhuast with 3" but as of now, i dont really see any restrictions with my exhaust....

 

i was going to do that too.
till someone showed me this:
it pinches to 2 inch

 

I know they'll drill you in CA. TX it's all good. Not sure about everywhere else

FYI: you will get a Cel if you go catless.

 

is it 2"?? it didnt look that small..... I would like to upgade my exhaust down the road but for now, the way i look at it, more flow, for free.......

well our downpipes are about 2.75" OD right? maybe that one spot is like 2 or 2.25 by 2.75"?? which i dont think is that restrictive..... well for someone with only a few mods atleast.....

 

yup i agree.
but i also liked the idea of having the stock emissions legal one layin around just in case

 

actually i had my dp off the other day because i was board and wanted to look for restrictions. if you think the o2 section is bad you should look at where the dp bolts to the manifold. it has to be under 2 inches there.


as a side note i have been running stage 2 for about 400 miles and the inside of my cat had lots of carbon build up from running rich. I think it would have deff clogged in a few thousand miles or so................ so i gutted it till i get a real dp.

 

i gutted mne also got the 02 sensor turned off loud now with my hearder and magnaflow but i don't like the idle sound

 

did gutting it kick on the check eng?

 

no when i had my hp tune i had they 2nd 02 sensor turned off so it reads everything ok

 

i will not have hp tuners till next month so i got a cel.


p0420 catalist eff below threshold. (no **** its not there lol)

 

check with your DMV to see when your next emissions test is. I just found out I dont have to test until 2011 and Im in Cali. Im catless and I had been stressing about what to do for the last couple months.

 

Here in BC new cars are exempt from the sniffer test for 7 years. Hence why I went catless.

 

good ****. you guys are lucky. I guess I am too since this isnt what cali is known for.

 

i could not go catless here cause they inspect and look for one,so I just gutted my clogged CA downpipe

 

I dont have hp tuners, and I have only a vauge idea of what that is, But I think I want to go catless. Does it make you car smell bad if you do. I have a friend that is catless and he smells like ass and no CEL. its also a civic so we give him hell.

 

i say catless, especially since anom says there are ways around the inspection in alberta. my cat clogged.. so i cut that bitch out :

 

mine does not sound raspy,how about yours?

 

the down pipe doesnt have that nasty bend for the 07s
