Cal,

Do you have catted downpipes in yet?

Hello Rich,

There won't be any Catted DP for EVO. There isn't enough to incorporate a hi-flow cat. You will need to replace stock catalytic converter to a hi-flow unit.

Thanks

just ordered it from you guys. cant wait for it to get here.

 

Thanks!

 

Ok cool - any recommendations on a high flow cat? And these are the V2 ones right?

 

Hello Rich,

If you can wait, Helix 3' high flow cat will be released fairly soon. If time is your enemy, ultimate racing hi-flow, or Random tech hi-flow will work as well. And yes, the exhaust and dp are version IIs.

Thanks

I can afford to wait - but I'm itching to get my TBE sorted at the same time

When you say fairly soon - any idea when that may be?

 

Is there anyway you record exaust note of this package?

 

Probably in 1 month!


please check the link below. Thanks

bump!

 

Is this package still available??And do you have the Ralliart drop ins??I would like the system,drop in and the MR diverter valve all at once if I can.Im in NY right now and wont be home until next week but I can pay for all of it on wed just so you dont sell out of any of them before I get back to FL.And that cat delete pipe..thats the new one,right??The one that wont throw the CEL.Let me know and ill call wed morning.

 

Nevermind on the CEL question....I didnt read the whole post before I replied...just saw the system and price and got excited.

 

Just to let other's know....I installed a full TB Helix exhaust with the cat-delete and i keep getting a PO420--->catalyst system efficiency below threshold (bank 1). I love the exhaust for the power increase AND sound but I am kind of dissapointed with the CEL issue. I am going to experiment with a few ideas to try to "trick" the ECU. BE CLEAR....this is NOT a knock against Gruppe-S. I have received nothing but EXCELLENT treatment from Cal before, during, and after all my purchases. I just feel people thinking of this purchase should know that this may occur. Maybe they would want to go with a hi-flow cat instead of a cat-delete. I may end up going that route. CAL, Is anybody else having this problem with ANY type of cat-delete pipe?? Also, have you had any CEL's with your high-flow cat?

THANKS!

 

Hey D evolved one,

Did you splice the black wires of the o2 sensor one at a time? The reason I am asking is because this topic also came up in Helix cat-delete threads. Just to clarify that one black wire is ground, and the other is the sensor wire that goes back to ECU. With that said, if you spliced incorrectly during the initial install, that might have caused the p0420 code to show up.

Thanks

If you had the two black wires mixed up then the "SES" light would come on.
