Hello Everyone,

Could some one help me or tell me what do I have to do to install a new exhaust system for my EVO VII?? I am concern about the two lambda probes on the EVO VII. What should I do?? Do I have to change my ECU??

Regards,

Cesar

 

Cesar-

Quick question you have a GSR. so it must be RHD, correct? The reason I ask is becuse only RS-IIs have the second O2 sensor after the cat. Or at least I had been led to belive this.

Hello Erik,

Thanks for your answer. My car is a GSR 2002. I will like to know what I have to do to put a new exhaust system to my car??

What is a decat??

Cesar

 

Cesar-

If it is a GSR then you will not have the second O2 sensor. If you do than it would be very unusual. A GSR should only have one O2 sensor mounted in the turbo elbow (O2 housing to Americans). To put a system on the GSR it should be easy. To get the most out of the mod some form of ECU tuning would be best. Some people get fuel cuts with intake and exhaust mods although the belief is that it's less likely on an Evo 7. Decat if you do not have periodic emissions tests.

Hello Erik,

That great news!!

Could you recomend me some manufacture for my exhaust system?

And a Distributor that I can fairly work with them to order it?

I'm getting a Fujitsubo RM-01A cat back with the fujitsubo downpipe and a Mines turbo elbow. It is a JAMSA system (not so loud.)



For a louder system the Blitz Nur spec or Apexi R-95 is the way to go.

I have stayed away from HKS since there exhausts are mostly mild steel.

Some places that you can buy them at.
