ob1 cat removale
 

i have a 95 z28 with one cat.i have a flowmaster 40 ser with single in duel out and intake.can i take my cat out without throwing a code?and how will it sound with my exaust.i like loud.

Re: ob1 cat removale
 

OBDI systems don't check for cats, therefore it won't throw a code.

thanks man i thought so just was making sure how will that set up sound?

Re: ob1 cat removale
 

I had a 93 Z with no cat and flowmaster muffler, it sounded great. Removing the cat will make it louder for sure.

Re: ob1 cat removale
 

Dont take out the cat... just replace it with a high flow. That way it will still sound good but you wont have to deal with the smell and possible legal implications. I really wish I had left my cats. :(

took my cat off when I did my lt's love the sound, smell isn't that bad but I do sweat a little more every time a cop is behind me

Re: ob1 cat removale
 

Take your y-pipe and cat off. Gut the cat with a pry bar or something and place it back on. Don't put any scratches or anything on the cat. I did mine that way and I love the sound. Also I don't sweet it when a cop gets behind me because looking up under my car everything looks stock and legal.

they sniff test 95's, no cats no pass

Re: ob1 cat removale
 

dont here test here for cats.i dont want a high flow cat cuz im doing it more to make the sound louder not flow more.my 94z had no cat with a borla muffler and i loved the sound.i never smelled anything.

I just welded a cat casing on my 3" exhaust so it looks like it is there haha :) I love the sound without a cat! Mine is very loud also

Re: ob1 cat removale
 

lol might try that

Re: ob1 cat removale
 

I hollowed out my stock cat for a year, it was loud and raspy, sounded "tinny". I have AS&M headers and a Flowmaster cat back. I put on a high flow Random Tech cat and it sounds much better, a little mellower, but much deeper.

Re: ob1 cat removale
 

Yeah mine sounds raspy until the exhuast gets warm then it goes away mostly :)

Re: ob1 cat removale
 

well im not worried about raspy cuz im going withg the slp catback soon lol i just like loud but i dont want a bad smell.ill see whats happens with it i guess.o i dont wanna hollow the cat cuz i heard it bilds pressure in the cat and make a wind sound like a whisleing.i have 120k do u think i will get sum extra power out of this also?
