Ok... well my vehicle just passed the ever so dreadfull California Smog Check.... barely... (because of ported head)
Anyways... as soon as it passed... i went home and decided to gut the Catalyc Converter.... damn.. it wasnt as easy as i though it would be... i poked, pounded, beat, and drilled the ---- out of it... till everything came out... now... theres nothing left.... my question to you people is.. was it worth the trouble less restriction... or was that restriction needed to create a bit of backpressure.... and when the turbo is slapped on there next week would it have been neccessary then to gut it..??

Anyone care to point me in the right direction...

gutting the cat will free up some HP when your car is turbo, probly wont do ---- for a NA car.
is it worth it? cost of gutting = $0, free HP =

Yes my son it was worth every last second now you will be rewarded with free hp and a turbo steup next week.. Now you must jump over the crouching tirger and find the hidden dragon.......

ha.. im glad florida doesnt have the damn smog test anymore... we run straight pipes now!! wahoo.....

traff1c

you lucky bastards.... no smog check.... so that means you can pretty much ---- with your car and do anything you want to it.... It almost didnt pass... because I ported head.... and it was pumping out a little to much (HC) but now i can go all out.... and be worry free for the next 2 years.... or pay 150 to have it passed illegaly

they make very slight differnces on na cars, they will make it feel alot more (raspier). On FI cars it makes big differnces in spool times.

uhm
why not buy a test pipe for 30$ and have the cat to put back on for next years smog.

now your gonna pay more in the long run.

Got to love Florida, I have also a straight pipe from headers down to my exhaust. Every once in a while I get Pulled over for being too loud, but they can't do ---- because of that down here, or at least they haven't.

Yeah I did notice the car sounds raspier when i accelerate.. but i noticed that the engine doesnt seem like its gagging when i decelerate... so i did notice an improvement... I wish i would have just had a bypass pipe made...to have kept the cat workable... but im pretty damn sure that the next time i have to smog the car it probably wont pass... so ill just get it done illegally... ---- i hate living in Cali...

I think you will be just fine doing your smog test. I have passed several times at smog test with no cats. Actually I did a test once, and My car ran cleaner after I removed the cat. Probably because the 185k stock cat was a bit plugged. You would be suprised how clean hondas run.
