I noticed someone saying that there are 02-03 cel fixes and 04 cel fix. i had a friend of mine get an extra cel fix for his 04 helix DP and he put it on mine (03 turbo XS TBE) and it worked just fine. Maybe its something that Gruppe-s knows that some guys don't. I think it was some kind of Pony cel fix or some thing.

 

so what did kenny do? 5 bucks eh?

btw, its really loud with my apex gt catback so i put the silencer
does anyone if this silencer is cancelling the power gains i got from the dp?

 

The silencer is canceling the gains you got from the catback, not from the downpipe. However, the HKS downpipe makes very very few gains over the stock, and those are all from removing the cat. Basically any other downpipe is better than HKS, although nobody else can match the price.

 

Unless you get the divorced wastegate tuby thingy welded on

 

im hoping to do that divorced wastegate thing.

can anyone please tell me what kind of resistor is the 04 wrx CEL fix

 

just buy one from gruppe-s.

 

and does anyone know what kind of mpg i should get?
i think im getting about 10-12 mpg with normal driving after the dp and the catback

 

it also backfires alot
is it running too rich?

 

Ryan, you and me gotta do some runs to see how far you can walk from me

 

haha, one day we'll see

 

10-12mpg? WTF, do you drive like a bandit? I'm getting twice that on average normal driving.




:banana:

 

i drive between 2000-3000

 

Is this the first tank since you put on your downpipe? Maybe it will get better on the next tank.






:banana:

 

city driving? constant rebuilding of boost?

 

WRX DP speaking, HKS is JUNK.
