4AT removing CAT
Does anyone know what is the Pro and Cons of removing CAT for 4AT?
will it make the car go faster or slower? |
im pretty sure that it doesnt do anything significant alone, maybe a combination with pullies would help more noticable.
|
does it have a side effect or will it make the car go lean? or will it disturb the back pressure? or it will give higher flow rate?
|
nah it should be good but like he said with other mods you'll see bigger gains like exhuast and such
|
you're going to gain maybe 3 hp, and it's going to make your car stink. You're better off just getting the rb reflash or something else that's not illegal.
|
oh ic. thanks for the info.
|
Also, large chance you throw up the annoying check engine light.
|
not to mention it'll be loud..
|
I think the RB reflash is only for the MTs.
I'm trying a new rear end gear soon and will post my seat of the pants results once that happens. |
i know it will be very fast on pickups. it will be amazing. but u will lose your topspeed.
but like all the singapore members say, how often u go 200km/h? and u also need speed cut for that. hehehe |
theres an RE flash on asia forums for AT. dont know if its still going on.
|
it was in singapore. no more.
i am located at east malaysia, that is north borneo to a lot of u. can't send my car over, too far, so too bad for me. |
I removed the stock cat and install the RP hi-flow. I did notice a change. It "seems" to pick up a little quicker. Also the thortle response is faster. Now since I dont have a g-tach or did a dyno, this is all speculation.
No cel yet. |

The idle was rough before the stockcat came off and the hi-flo went on. So I would say no.
|
Ive been running the stock cat and exaust for a while. I just put a strait pipe in place and gained 20 HP. Im shure its not as dramatic without FI but its proven the less back pressure the better on power with a rotory.

^ 20 HP... sound tempting.. did you dynoed it?

He said the gains were more dramatic because of forced induction. I'm sure he did dyno it since he's working on the 4 port blower at Pettit.
