I was thinking of pulling my 3" cat and putting a gutted one that i have on the car . I was told it has a new high flow cat, not sure if its true. With the gutted one will the car gain any power or sound from this.

thanks

 

it will be louder, raspier, less low end torque, more popping noise, and maybe slightly more HP in higher RPMs.

 

Nice screen-name.

You'll gain a handful of ponies from it, and you'll notice a raspier and louder exhaust note. Some think it sounds great, while others do not. A straight-pipe would be a better alternative, to minimize exhaust turbulence.

 

i actually lost hp thanks to my offroad pipe. When i put my motor together i had several degrees of KR then when i put a cat, back on the KR went away. It felt way stronger after that.

 

any one else , 2 good , 1 bad. I was ready to run out and do it then z95m6 posted.

every time i see your sceen name i think its my postbut then again yours is newer

 

I forgot top write that the car is stock, only mods are filter and 3" flow master exhuast. this might help

 

the gutted cat seems to help out on the bottom end and the top end, i have a little more pull on the top end for sure.

 

Gutting the cats doesn't do jack for the car's performance. I am just polluting the environment more, and after the headers, my car doesn't sound all that impressive. Don't do it, it is a waste of time. If you want to do something good, get a off-road pipe.

 

My cat is gutted and the whole car smells like gas at times. Especially sitting at a light, my guess is that the wind blows it into the cabin. Either that or something else is wrong with my car . I'm definatly thinking about going to an aftermarket cat.

 

I gained quite a few HP from my ORP, and i didnt notice any loss in the low end. And i love the sound.

 

It seems to help mine out. As for the gas smell i have the same thing but it was there before i changed the cat so i dont think thats it, you must have the same problem that i have .

 

i dont notice much of a gassy smell

 

no , no, mazer3800 said he gets a gas smell , i had the gas smell before i did my cat so i know its not the cat. not sure what it is
