    Anyone else on here running loud exhaust on a 2nd gen? Ive got a single in dual out cherry bomb extreme muffler, dual 5" tips and no catalytic converters. Ive never heard another v6 tacoma sound like it or any v6 for that matter. Not annoying and raspy, just loud and deep kinda like a straight piped cummins imo.

    When I had a flow master 40 series with 3 in inlet and outlet with stock piping it rumbled really nice and gave it aggressive soud instead of a rice

    Remember that in cab and exterior sound is different. Honestly too loud is dumb. Also removing the cats will cause some low end power loss.

    I like my cats. They like to play fetch and curl up next to me when they sleep!

    I don't think so, they honestly don't even check if vehicles have cats or not, I just got my inspection done last week and was out like in ten minutes I didn't even seetp them do any testing at all

    I've never can cats in my entire life till this truck.. If you OBD2, you can pass emissions without them and here in AZ they don't check for cats at all.

    If you are OBD1, just put a hallow pipe on there, and swap the cats back on for emissions. Take off cats once you pass and buy the 2 year so you don't have to mess with it again.

    Basic safety check; does it stop, do all the lights work, etc., then they plug into the OBDII port and if your code free, you're good to go. If you are not OBDII, there may be a sniff test, but there is no visual check done.

    Modern catalytic converters offer no restriction to teh engine. Removing them is pointless.
