as some of you may have read i got a dynomax ultra-flo put on my car this morning, and it sound real nice compared to my flowmaster...i have just been putting two and two together reading info. from hear and there, and was thinking about getting a *carsound* cat for my car...i live in se. missouri so there is no emission crap to worry about...im just wondering if it'll help or hurt me over my gutted cat i have on there now.

i agree, like i dont got to worrie about emisions, il like to take the catalitic out but i dont know if it well hurt my car.
lets hope we get answers.


i got a flowmaster series 40 mufler and she sounds nice!.

 

!Cat

 

get some longtube headers custom y pipe=no cat

 

I ran my car for maybe 2 years with an off road pipe and after i put my motor together i got sick of the noise. I found a low mileage stock LT1 cat and had it welded in. The car felt much stronger and it took away lots of knock retard. It cleaned up the sound to.

 

so do you think a carsound cat would be a bad idea?...i can always take it back off. and could you please explain to me what spark knock or whatever its called is.could i possibly have that? i just dont want to lose any power that i have, i just want the sound cleaned up a tad bit, and the gas-ie smell to go away.

thanks
steve

 

knock retard is when your car pulls timing out for some reason. It can be caused by detonation or people have found it can becaused by excessive noise from exhaust or parts rattling or other things. My borla and offroad pipe must of just been to loud i would pull almost 4-5 degrees of timing at idle. After i put my cat on it pulled no timing. Obviously you can't make power with out proper timing.

 

Previous posts have said that too much noise in the engine bay can cause some slow down.Do you use a knock module?Those after market lifters can be the noise problem.The computer hears this noise,and adjusts (slows down the stuff),to make the car drivable.(the computer hears spark knock,then adjusts for that.)Anybody else?

 

CATS are for people NOT MAKING ANY POWER! Nuff Said!

 

Or people that want to pass emissions safely

 

Your obviously an idiot.

 

He just said he didn't have to pass emissions you stupid blind ***! I have to pass emissions here but you don't see me crying. Prolly cause I know a lot of people that aren't homo **** like yourself and will hook it up

Not to mention ANY car that can pass emissions ISN'T making power as well.. So once again NUFF SAID!!!!!

 

Oh your right I forgot me and everyone else I know running 10's use CATS how stupid of me

Then again what would you know. 355 with an itty bitty cam.. Prolly put down 350 to the wheels if that

 

I dont remember who, but there's someone roaming the boards with a boatload of posts, making north of 800hp through cats :-p. I agree with what your saying, but there are exceptions

 

Either way, no one builds a race car with CATS Sorry...

You won't see Tanner Bosnali, Jordon Musser running CATS... $hit I don't even think Fred (Injuneer) runs CATS and that guy does EVERYTHING by the book!!
