Hey forum,

Arma variable exhaust valve: http://www.armaspeed.com/eng/goods.php?act=cat&no=53

I am in contact with Arma to order a variable exhaust valve for my 2009 is250 awd. They have requested the "diameter" of my exhaust as they have options available in 63mm and 76mm... Arma has a youtube video with the arms vet on an is250, so its not like it won't fit. I have a stock exhaust.
What diameter does an is250 owner need?
They also asked if I had an OBD2 system (Don't all cars have them nowadays)? Is there a port that I should be looking for under the steering wheel?

Thanks in advance!

 

You think they'd know since they build it for the IS. Yes you have OBDII.

 

What size do I want tho? Lol

 

UPDATE

I was unsure which part of the exhaust they wanted me to measure, so they sent me this picture....:

This is becoming frustrating. They have two options to offer: 63mm diameter and 76mm diameter... which one should I order?

 

i will recommend 63mm, if you weld like this photo, your car is going to be sound like F1 cars.
IS250 has OBD2 system, don't worry.

 

What's the use of this?

 

They claim it to aid performance, but who knows.. its mainly for sound.... In my mind, it reminds me of an e-cutout

 

How much are they asking for this? Electronic cutouts are not too expensive to begin with, and can probably do the same thing

 

Sounds like $470 not including shipping and import tax.. I will try and get it down though..

E-cutouts all sound way too raspy... I'm hoping this is a better alternative

 

I want to ask something about that item. I have a custom exhaust without the 2nd cats. The car have some drone between 2k-3k revs. That product can help me with the drones? In Auto mode if open after 3.500 revs the drones will be eliminated?

 

in the video, it sounds good. anyone want to try

 

Alright so I finally got a response back from ARMA, and they say the exhaust diameter for the cars THEY test in TAIWAN measure to 63mm..... But they don't know what ours look like here in the Canadian/ American market..

Again, the options were 63mm and 76mm
