Any recommendations for a dp with cat that has the stock connection to the catback system? Is there one? Or are most cat-less and is this where the actual power gains come from?

 

so far there is

Alta 3in Catted Dp. that will require a little modding to get it to fit with you stock/stratmosphere exhaust i believe

there is the ragazzon 2.5 DP, that one is a DeCat, but links to your stock exhuast

lastly, you could have Exhaust depot custom one for you with an open flange, also a little modding to be done

hooray for so many options =[.....

cat-less usually nets more gains because of less restriction, however you may experience, noise, smell, etc.

 

Hi

I have a Ggr downpipe 2.5" with catalytic and it bolts to your stock exhaust without any modifications!! I want to go with the ragazzon without the cat because a race a lot in the track, if you want a downpipe I can sell you mine cheap!

 

I have the milltek downpipe (200 cells) installed it fits to the oem exhaust system!

 

Way motorworks also has one now. I don't think it's on his site yet but I've seen it. Very nice.

 

Can you guys tell us how much you paid and where you ordered from?

Also, if you get any CEL's, how did you deal with it?

 

ALTA DP you just have to deal with CELS everything I try I get a new one its like a shitty game.

 

Do the CELs affect the driving? Do Check Engine Lights cause Limp Home Mode to activate? If not, I don't think I'd be bothered by a light on my dash.

Is ALTA's new ECU solution going to "ignore" the downpipe CELs? Hopefully.

 

Cel's dont affectthe driving

Only the light turned on!

 

Yah just the light well it does bother me because if I want to pass inspection it needs to be off =(
