hi,
im going to buy and hks ti carbon exhaust,,i really like it..
one friend of mine told me when i decide to put new exhaust on the car i have to upgrade the ECU ,if not the exhaust wont make any difference on the performace ..is it true?
or do i have to reflash the ECU at the same time??
thanks alottt.

 

The carbon ti is just a cat-back exhaust. They are nice looking. Diameter is 75mm=2.95inches. Lancershop and Motion Garage both sell them. Since you have an IX, you may have to do (although you are is Slovakia so it may not apply) the following, per Motion Garage:
"Additional Information:

2006 Evolution Installation Issue: This exhaust requires an o2 sensor plug in order to be installed. In 2006 Mitsubishi USA placed the o2 sensor on the catalytic converter instead of on the cat-back mid-pipe."

Are you going to get a 3" downpipe and high-flow cat as well?

I think you can go a little while without a tune if it is a cat-back only, but get the dp and hfc, and then get a tune. You will see better results.

Good luck with it.

 

thanks a lot,,,but i didnt get it with the o2 sensor what you were telling about...

 

for that kind of upgrade you don't need anything yet. just put it on and drive the car. if you want a tune, then try intake, downpipe, exhaust, MBC 21 psi, and bigger fuel pump. then you can feel the diffrences. if you just put on an exhaust and you wanted a tune it would be also like a waste of money. pull like stock.

 

ohh thats what i tought,,thanks anyways...

 

and what will i do with the o2 sensors ???

 

getting a stock car tuned will get you hp gains and better fuel economy. Adding exhaust doesn't require a tune but it will help you get the most out of the mods.

 

PM'd about details, I'd go with a full exhaust system from the turbo back. It's a basic tune and will give you additional power, etc. Great starting point.

 

thanks mellon and 80210 i allready had some meeting here in bratislava about this and they said the same,,so you or they just comfirmed the same thing what you guys have been saing here...
