LOL, yea its illegal!!

so.

 

Actually, cant you remove the Cat on some cars...

I thought i heard it was legal in some states, dont know about florida but it was possible in Minnesota i believe.


(Im Probably Wrong)

 

not that it's legal, just that emmisions testing is no longer required in this state.

and................. opinions on my idea please.

 

Yea.add A Exhaust Cutout Too!

 

dont change the rest of the exhaust at all just get a cutout and modify the connection between the cat and the downpipe to fit the cut out

yea so you should actually read what i posted. a cutout was one of the major parts of the exhaust idea :hide:

o.k. so then it'd be like running with only exhaust manifolds... no thanks. :helpless:

I'm going to end up doing this. but will probably change the mufflers to some polished ones anyway, just for appearance. i'll let ya'll know how it goes, if and when it happens.

 

i ran straight headers, thing was a loud ass beast

right, so i'm trying to avoid that.

 

right, so i'm trying to avoid that.

i sure wasnt

 

I think it will be louad as hell without the cat.....im not sure but i do think the cat and the restrictor are incorporated

 

Oh also youll get check engine lights without a cat (i looked into doing it in my cts)

OBD I buddy....

also, you can put O2 simms in your CTS and not worry about an SES light, but warranty work would get ya.

 

$10,000 fine if they catch you....federal offense, not state. Hollow it out, don't remove it.

 

Gut The Cat! Gut The Cat!f___ The Cops!!

LMAO, i bought the car used. how am i supposed to know what the previous owner did to it...

Cats are stupid anyways, unless you have emissions testing, throw it away. If you're worried about drying from air pollution, start smoking.:annoyed:

As for the original exhaust idea, I think it would be about perfect. Great flow, yet muffled enough to sound pretty good...not TOO loud. The louder the better, obvously, though

How do you hallow out the cats and what are the results?

 

If all you do is hollow out the cat with no other mods to the exhaust (what I have now, just did it for fun while the exhaust was off) you dont get any more anything, except for a bit of resonation at the righ RPM's. Pointless unless you're going to do full exhaust. In that case, it would mean just a bit less restriction which = more flow. The cats on these cars aren't really all that restrictive anyway, but the way I look at it, there is still material in there that gets in the way. If you look at www.caddyinfo.com, they have some info about exhaust ideas and flow factors....

 

i decided just to put a 2.5" cutout in after the resonator.
