How does this divorced downpipe affect (if any) the flow in this section if I’m running EWG from my manifold and blocking it off on the turbo?
Flow is not negatively affected by this design
I've run into issues with the speed 3's version of this divorced DP and the bnr s3 turbo's flapper smacked the inside so it was unusable. Will i encounter the same issue in a speed 6 with a bnr s4? Or is it only designed for the small K04 flapper in mind?
Our parts are designed to work with the OE or CorkSport parts. We can't confirm fitment on other companies parts.
Hi, does this kit come with new gaskets for the new connections?
It comes with one flat gasket.
I’ve Already bought your test pipe to eliminate the unmonitored secondary cat converter. Is this high flow cat getting monitored by the primary or secondary 02 sensor? Do I need to buy the one with the high flow cat and pull your independently purchased test pipe? I cannot have a CEL due to not the correct cat in place. Thanks!!
The high flow cat in the long downpipe is in between the primary and secondary. This is the same way the OEM cat is positioned. The secondary O2 Sensory will contain an extension harness to allow it to reach further since the Cat has to me moved a bit further down.
I have already purchased this non catted downpipe and love it. i am looking to upgrade my turbo and my question is, will the non catted racepipe work ok with the CST4 drop in turbo upgrade? I have read that divorced downpipe's can cause issues with the internal wastegates?
The CST4 will work just fine with the CS Downpipe
Will this down pipe work with the atp gtx3076r drop in turbo.
Should have no issues as long as the flange is for the 5 bolt
Does this downpipe fit a stock 2006 MS6? Since the stock diameter is not 3'. If no, what other mods I need to put this downpipe on? And what is the difference between the short one and the long one? Thank you so much.
You can run this on a stock MS6. I would also upgrade your HPFP while doing this upgrade.
your race pipe says its not for the street and only for track so why say we can by the catted down pipe with the race pipe ? what would be the point in having the catted down pipe if the race pipe is illegal
James, if you buy our downpipe that includes the high flow cat, then you will not need a seperate racepipe. The long downpipe bolts right up to the catback.
This downpipe has no cat between the two 02 sensors, but in a previous question you said it would pass a plug in check, how does that work, since that cat is the monitored one?
As long as you get the high flow catted downpipe, you should be fine.
I have a SU test pipe installed with a custom CBE, will the CS shorty downpipe fit my current setup? Also, can you confirm there is no CEL's associated with the install of this downpipe? Thanks for your time (and products!).
The CS short downpipe should work just fine. If you don't have a catalyst in your exhaust system, there will always be a chance that it throws a CEL.
Will this pass California SMOG Inspection? Is there a C.A.R.B. exempt sticker included?
California is a tricky one. As long as you buy the down pipe that includes the high flow cat you should be able to pass emissions. The only performance part we carry that is CARB legal would be the Stage II Power Series Intake for the Mazdaspeed's. I can't make any promises on your car passing emissions with the long high flow down pipe, but you should be ok.
The stock exhaust system has two cats, right? When installing your High Flow Cat Downpipe with Racepipe, do you end up with one or two cats? Liking performance and trying to be a friend to the environment, I'm looking for a low-pollution performance solution, presumably with two high-flow cats or one really good one. Are you selling what I'm seeking?
The stock exhaust system does have two cats. However, the rear cat is unmonitored. Your best option would be to purchase the long high flow catted downpipe that includes the race pipe section. You should be just fine running one high flow cat on the downpipe.
Will i still be able to pass the emissions test in ontario, canada with the catted downpipe?
It will pass a plug in check but not a tail pipe check.
