Default are there laws against 3' cats?

I got my set of hooker lt's..and I took them into the local exhaust pro's to have them quote me a price to get them installed...I also got a pair of carsound 3' cats..first of all they said the lt's are too long and wont fit.. <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" /> ..then they said since the original cats arent 3' its against the law for them to put um on.. <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" /> ..has anyone else heard this <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" /> before?!!!

3 FOOT or 3 INCH? Cause ' = Foot, while " = inch. Ive yet to see 3 foot long cats (or even 3 foot wide) and but im fairly sure cats are longer than 3 inches, but the piping could be 3" wide.

Just tryin to clarify so im not reading too much into it...cause a 3' long/wide cat would be overkill, imo.

The way I've seen it, it's illegal to remove a
properly functioning cat. So you would want to
tell them you suspect they're not working right

In my area most muffler shops won't touch headers
(and we're in a no-smog-**** state, too). But
there are one or two shops that are known for a
more cooperative attitude. I bet it's the same
all over (except KaliFornicateYa maybe); bunch
of wussies afraid of losing their business and
getting fined, and a few good ol' boys who are
willing to help out a friend of a friend. Just
need to find the regular guys and give them your
business instead. Ask the "old school" guys you
run across, if they know the secret handshake.

Yes, it is illegal to do b/c of the above statement that it is illegal to remove properly functioning cats. You cannot remove them w/o some documentation that says they don't work (not sure how that works....but could be you fail emissions, etc), you cannot move the cats from the stock position either(hence, all headers but shorties are illegal). I do beleive that is because when the cat is further from the engine it takes longer to heat up and function properly so you put out more exhaust crap while it is getting warm. ( <img border="0" alt="[shoot]" title="" src="graemlins/gr_guns.gif" /> emissions )
