i live in cali so no o/r pipes for me... was thinking would an exhaust shop be able to remove 1 cat on each of the pipes and just welding in a straight pipe?

Id think this would make it a little louder and a little less restrictive, but nothing spectacular.

what you guys think?

most exhasut shops wont do it. its illegal to remove cats in CA. you can only have the stock H pipe with all 4 cats on it.

California is GAY man!!! wtf?! I wouldn't be able to own my mustang if i HAD to leave the stock cats on there. Can you even change it for Aftermarket exhaust with 2 cats? Does it have to be Factory cats, or does it just have to pass emissions?

keep the stocker intact and just buy an o/r pipe, when it comes time to smog uncrew o/r and put the stocker back in..simple and works
And every cop in cali is to stupid to realize the different between a stock sound and a O/R sound.... :shrug:

honestly most dont care. ive had friends pulled over in their stangs and all the cops ask is where they got their exhaust from. i had a cop pull up next to me when i was i nmy stang and he said "looks nice, get a borla catback and a o/r x pipe and that thing will sound awesome."

the main things to worry about are jurisdictions that actually care about emissions violation tickets. also when you are near a cop dont make it obvious that you have a loud exhaust, namely keep it under 3k. also look out for the mobile smog stations. they run traffic down to 1 lane and randomly pull a car out and make them get a smog test right there. if you run they send the CHP after you. there was a guy on SVTP that got his cobra impounded for 30 days for having a catted X pipe.

now thats a cool cop... cali is really homo man... i would never ever live there... hell if somebody gave me a house there, i would sell it and live elsewhere...


thing that pisses me off is gay cali laws tend too infect other states...
 
Yes it has to be the factory h pipe to be legal in Cali.
Don't remove the cats or it is possible depending on the cop
that you can get a 1K fine,impounded car,or even tooken
to jail for a few nights.I say stick with the factory h pipe
if I were you.
