Hey Guys,
Im picking up my Evo IX on Friday!!!! I have a HKS Hi-Power catback exhaust sitting in my garage waiting to go in. I have one quick question. If I Install the RSR Downpipe (the long one). That will connect to the HKS catback and make a full 3'' Turboback correct. Im sorry for sounding like a noob, but im kind of new to the Evo comming from a STi.

 

You will need a cat-delete pipe. But most of them throw a CEL, so you will also have to purchase the sensor thing that turns it off. Sorry, i cant think of what it's called right now. lol.

 

Or run with the CEL light on . After awhile you get used to it being there

 

haha, im used the the CEL light...........Sti loves throwing them

 

O2 simulator. There we go. lol. Some cat-deletes (Test pipes) come with it.

 

Isnt there a downpipe that goes right to the catback??? Where a cat delete pipe is not necessary?

 

English Please and do not insult other members in ahy language.

 

Yea, but sometimes it's cheaper to buy the cat-delete, and the downpipe seperate. I know DC makes one.

 

That is, DC that makes the downpipe that eliminates the cat.

 

What downpipe do most of you guys run? Im going to assume 3'' is the best?

 

Warned again.

 

I think the Majority run either Helix or Buschur because of the complete 3" Diameter with no neck downs.

Other popular Dp's would prolly be the HKS , This is only my perception.

 

ok, and a good cat delete to go with a helix downpipe would be?

 

pretty much anything that's 3'' and reliable....
