Okay, I went to Super Autobacs to see a box of catalytic converters that say "high flow" and "smog legal." Anyone know anything about this? Even if it's smog legal, does it pass smog? And will it make your exhaust noticeable louder?
ever wonder why they allow the sale of aftermarket mid-pipes knowing full well most of them being sold arent for off-road use? silly gov't.squares98 said:it is illegeal to mod your stock mid pipe. The complete Magnaflow x pipe is cheap through partshopper.
btw, quit shopping at super autobacs, you drive a ford.
TrueBlue03 said:yep in cali, it wont pass. ....which kinda defeats the purpose of getting a catted x....thats why i just went offroad.
its illegal to touch that stock midpipe unless its damaged in some way preventing it from working properly or destroyed...and even then, you cant replace it with an aftermarket midpipe with hi flow cats because it wont pass smog.

They may be primarily a shop for rice cars, but they sell lots of Mustang stuff including handheld tuners to Saleen 3V Superchargers
bdcardinal said:exactly, keep the stock H pipe and swap it. but dont complain if u get pulled over.
bdcardinal said:ya, only an unmodified OEM pipe is legal. there are no legal replacement cats for newer 4.6L mustangs in CA.
