Do you guys have cats?

I am looking to go no cat and just a straight pipe from header all the way down to my mazdaspeed exhaust.

Does your car perform well with no cat?

Thanks fellas!

 

Yes, but I'm running my cat right now, cuz I didn't like how loud my middy was. Looking for a quieter one. But there's the CEL and gas smell when you're stopped, and you won't pass inspection with it.

 

I have Dogs

 

There is no inspection here in AR/Ok....

So i still wonder will the car run better with no cat or just louder? Looking to spit some flames too. Lol.

 

Say what??

You'll probably get a small amount of power, but it won't make it a monster or anything. And you may get some flames, too.

 

lol bout the flames....

But it will run ok with no cat? Wont idle funny or anything? or loose any kind of power that it already lacks? lol

 

Presuming you're going from stock cat to straight pipe, you will prolly get ~10-20hp potentially (presuming 3" pipe). As others said, it'll smell like a gas spill behind your car, and you can melt your shrouds with flames, so up to you if you *really* want flames. And, of course, there's the ever present CEL that will be on, and it will be much louder.

 

you guys know anyone with a custom setup up from a local muffler shop that has done this?
Is it a Nasty honda fart can loud or a decent souding roar loud?

Thanks for all the help guys.

 

go with a cat delete with a couple of res. i run an AP Cat delete and a Greddy catback and its not too loud then again the greddy is made for the streets, and the flames arnt big at all. may smoke a little..

 

I want something loud as fawk but not honda fart can annoying. I was thinking going 3'', cat delete all the way back but im scared thats its guna be like honda fart cans... Id figure that this will be the loudest in the world. lol

 

May want to be careful of the attention that will get... you know, the kind with red and blue lights.

 

turbo xs cat deleate and exhaust and no CEL

 

not to flame or anything...but this seems like a very childish statement...Something i would expect from a 16y/o who just got his liscence and has no clue of the consequences.......Like getting pulled over for sound violations, and not being able to speed because each time u press the gas they can hear you from a mile away. ....just a thought.....

 

if you want super loud go with a 3 inch non resonated midpipe and the hks hi power that should hopefully be loud enough for you

 

so what are you trying to say?

 

I recommend a high flow cat.
Get a straight mid pipe and weld in a Davesport cat.
Plenty loud without all the stink and you'll still get some power gain.

 

This topic has been discussed to death. Do a little research. There are many members running racing pipes, high-flow cats, etc.

 

lulz

anyways i have a greddy cat back and an ap duel rez med pipe they sound great and is loud when you romp on it and not bad any other time

 

Man i got the Agency Power Headerback exhaust and its so loud, and not ricey loud... but beastly loud and i can really tell a difference in performance... just be careful no cops around lol

 

thanks for all the suggestion guys.

 

any suggestions on how to handle the annoying CEL after installation of the Agency Power exhaust system?? i took off my CAT and i hate driving with the CEL on....
