it will not be cheaper to have custom l/t's fabed up. the material cost alone are about the same or a little more then what it would cost to buy them. not add the labor and it will cost a lot more.
with a cated shorty mid pipe you should pass a sniffer or computer emissions test but i dk about a visual inspection.

your best best is to call the local dmvs about legal exhaust modifications if you are inspected.

and like 02 said, youre better off buying long tubed (mac long tubes with ceramic coating are best quality and price around) because fabricating something will 1) cost more and 2) need more custom fabbing for the rest of the system.

you will gain a lot of top end hp and flow much better. look at 12-15 rwhp, more with intake mods and a tune.

well when i got my mustang back in september i had to get emmisions checked before i could get my plates, and i think ohio has always had emmission checks...but anywho...

If i bought the long tubes, would it be easier to have them fab up the Hpipe with cats cause i was already going to have them cut behind the stock cats and put in a true dual, but if its worth the money then i would go with long tubes shorty h with cats and flowmaster 40s out the back

idk, might have been a local city law or something, I wouldn't think emission laws would be anything other than state law but idk...I've never had them, and neither has any of my friends...

stop putting down MAC LTs. They are a very good quality header, and even the V8 guys recommend them over kooks, SLP, BBK, etc. Dont say that only the V6 MAC LTs are low quality too. Theyre all made out of the same material...just with one less runner. Yur just jealous cause you have shorties. :tomato
