i have a cat on my midpipe i want to know if i will notice a diff in power withoutit. i know it will be louder.

i have a stock 13b motor
to4z single turbo kit... from rx7store
pfc
hks catback
fmic
12 psi

 

Of course it will have more power. Of course it will be louder.

Why bother asking?

 

If you don't need to pass emissions tests, sure.

 

If you do need to pass emissions just keep a hi-flow cat on hand ^_^

Be sure to get your map adjusted after removing the cat though!

 

ok thanks i dont need emissions were i live so i will remove it thanks.


should i get it retuned after i do so?

 

if it was tuned with a cat on then yes.

 

Yes, I would most certainly, without a doubt, get it tuned for the free flowing exhaust. I wouldn't even install the midpipe until it was at the shop to be tuned.

The good thing about that is you can then safely run free-flow and, if need be, you can put a cat back on and still be perfectly safe to beat on the car (though the car will feel noticeably sluggish with a cat). I would not ever, ever, Ever, EVer, EVAR, run this car with a free flowing system if it weren't tuned for it! But that's just me.

 

i'll take your advice and take my mide pipe to the tune shop and put it on right before i get retuned. but i also been having this broblem its wired. check it out
