Corksport Downpipe

yes they do have an exclusive product, no other company said 'hey lets make a piggyback just for the speed6 with no other vehicle in mind'

thats all i was saying, i told you guys not to take it to heart. ****** a (smash)

The standback is not dedicated to any car. It can be used for all - it's just a matter of finding the right wires. I think they're planning to try it on the BMW 335i.
 
Alright no more talk if they are monopoly or not or this will get locked.

Get back on topic of the corksport downpipe.

thanky!

i understand its usable on other vehicles, that would be interesting to see how it(cpe ems) does compared to the xede on the 335's.

i was just cruising the mazda3 forums, looking for their veiw of the corksport downpipe. and wow i didn't realize the ms3's DP were so much different. they are bent all over hell

Are their engine bay that much smaller?

Hopefully somebody will buy it soon and post in here. I'd really like to get it in the future, but I need to get my other car running before I can mod the MS6 to much.
 
For all those who have one, How do you find the CP-E Downpipe?

i have sold two corksport downpipes this month for the ms6, i don't think either guy is a forum poster though, not here any how. i have dealt with CS for a long time and have no reason to doubt thier quality. they've been doing mazda parts and service since some of us were in diapers. ok maybe not that long but long enough.
 
Just ordered the DP From Protegegarage, i'll be sure to write a review/sound clips the whole nine yards :o
 
Well, I placed an order with Ken as well on Friday (2 actually - me and another local guy).

From dadasracer (& others) install tips (much appreciated btw) here's what I think I need to prepare for:

1 - remove O2 sensors while hot
2- take turbo bolts off first so as to make the mid-bolts easier to remove to get the stocker out in 2 pieces
3 - exhaust wrap the DP as I'll lose the heatshield the stocker had

Anything else you guys that have done a DP install can think of or suggest?

Do I need to remove the intercooler? I believe so.

Also, what have you all done for an MIL eliminator? The diode trick or the fouler or ??

Thx all!!

i think the corksport comes with a CEL fix, pretty sure it just holds the sensor further out of the exhaust flow than normal to keep the signal within an acceptable range.

and ya the intercooler will need to come off probably..thats fast though
 
.so thats why it would have three. [endQUOTE]

I'm not sure you still got it? The stock system only has the 2 O2 sensors, 1 before the pre-cat and 1 after the pre-cat. The ECU measures the voltage difference between the 2 and will use that data to determine if the pre-cats are functioning properly (ie. the exhaust is getting "scrubbed" by the pre-cat).

If you were to gut the pre-cat or install a catless DP, the voltage would be the same and the ECU would register that something's not working and set off a CEL. That's why you need to do that diode trick to fool the ECU into thinking there is a voltage difference and therefore no CEL.

Any mentioning of a wideband O2 sensor for tuning is one that is put in OVER & ABOVE the existing 2 sensors and as was mentioned above is best put in the testpipe (where I have mine). At this point you'd then have 3 O2 sensors (the 2 stock ones for ECU monitoring & the 3rd one for AFR monitoring for tuning).

I think some of the confusion arises because the pre-cat stock O2 sensor is a wideband sensor ... just like the 3rd one used for tuning. The after-cat O2 sensor is a narrow-band sensor that cannot measure AFR accurately.

Hope that helped. :)


Explain this point again. I have the Cork DP and have a CEL for a slow O2. I called cork and they gave me a fix but if its no big deal then I won't perform the fix and just clear the CEL.
 
I'm not sure I can add more of an explanation to that Speedi3 - got any specific question?

If you're always checking the code when you get a CEL then you're ok if you don't mind clearing it everytime. The risk you run IF you don't check it is that the CEL is for something OTHER than the DP O2 issue.

If it was me I'd be performing that fix you mention.
 
Had the fix completed today. It involved drilling a 13/32 hole into the extender for the 02 plug. took less than 15 minutes cel is gone. BUT so my power or at least it feels that way. I'm going to disconnect the battery to reset everything before i conclude.... THESE SPEEDS are very tempermental...
