would i pass emmisions with an offroad, bbk equal headers, and flowmaster 40 exhaust? how much better does the o/r h pipe sound than the high flow h pipe? who the hell makes h pipes for stangs anymore their impossible to find

thanks !

off-road = no cats = no emissions cleansing = no passing emissions tests

The MAC O/R H sounds badass with the 40's. I have the same setup, and I get compliments ALL the time on the sound.

You may not pass the visual inspection, but i have an o/r h-pipe and flowmasters and i pass emissions. I am riding so low that they didnt even bother looking at my h-pipe for cats. Yeah and any o/r h-pipe with flowmaster 40's sounds real deep and not raspy at all.
