would the hi flo cats make the stock sound deeper and louder? or is there no point to doing this?

thanks

 

I have the Crawford CATS, and they do make the Stock sound deeper and somewhat louder. Not annoying.

 

Same here! Agreed, one of the best mods. Esp for the money. I've been VERY happy with the R/T's so far.

 

so i guess the question now is R/T or crawford? and how much should i expect to pay for install?

 

oh, and are they both ca emissions friendly?

 

cRawford's site says theyre Race-only application... i assume theyre not emissions friendly then??

 

i made some calls, and the guy at Random tech cats told me that as of yet, no aftermarket hi flo cats would pass OBD although they would pass emmissions. i dont know what obd is, but if it creates any problems for when i want to sell the car (in CA) i wouldnt want do put on the cats

 

well, i searched the internet and the OBD is either "On Board Diagnostic system" or the "Organization of Black Designers" .
Here is a link to both.

anybody use the kinetix cats with the stock exhaust? my car is bone stock performance wise. i am hoping to do this first! does the kinetix/stock exhaust sound deeper/louder or is is raspy?

thanks!

 

Why not just test pipes if you dont live in CA?

 

thanks for the detective work Ragtopz. im thinking there has to be someway of tricking the obd.

 

i have the rt's with the stock exhaust and i love the way it sounds. its suppose to pass the sniffer test but will probably not pass the visual. if you guys (arash or tulene) wanna hear, i'm in san francisco and we can meet if ya like.

 

Hey there mgl. . . thanx for the offer! i'd like to take you up on that! you car looks amazing too, would like to see it. im in soma, pretty centrally located. arash are you in?

 

They have to put that on their advertisement because it is illegal to change your cats for the first 50,000 miles. Crawfords will pass emmisions.

 

thats really nice of you MGL, but im all the way in walnut creek. however, sometime next week i have to take my other car to the mercedes dealership somewhere in sf. a potential buyer in the city wants to have the dealership check it out. so if you happen to be close the sf mb dealer, i would definately like to here it and check out your car. i love that picture by the way.
so im just wondering, how do you pass the visual then? do you know someone or do you plan to take it off beforehand?

 

what is the pros/cons for the

Labree Hi Flow

RT Cats Hi Flow

Crawford Hi Flow

and

Kinetics Hi Flow

 

I don't know about the rest but I have a (BBs in a can) rattle around 3-4k with my RT Cats. Not happy!

 

ok i just ordered the kinetix cats and a popcharger. cant wait!
