Get maximum turbo performance and dramatically increase torque with the Mazdaspeed 6 Power Series Downpipe. The CorkSport downpipe has been expertly designed to replace the restrictive element in the Mazdaspeed 6 stock downpipe. Mandrel bent piping is used to create smooth exhaust flow for dramatic increases in power. During initial testing, the CorkSport Mazdaspeed 6 Downpipe showed power gains of 26 horsepower and 32 ft. lbs. of torque at the wheels.
For lasting corrosion resistance and reduced heat transfer to the engine bay, the CorkSport MS6 downpipe uses polished 3? 304 stainless steel and features TIG welds that offer superior arc and weld puddle control for a cleaner appearance and precise weld bead control.

Awesome product, instructions were very clear and it makes for an awesome upgrade. However my only issue was getting my O2 sensor removed, but outside of that it makes for a deep and aggressive sound for my Mazdaspeed 6

Nicely crafted piece and appears to do what it says for power. I have no dyno figures to compare but it feels like the turbo spools up much faster. The install was pretty simple once you wrestle the big honkin' stock DP out. I have two problems/concerns:
1. The stock cat-back has a flange that is not completely flat. The flat flange on the DP left huge gaps and I had to grind the cat-back flange down do that the gasket would actually make contact. Maybe CS should come up with a different flange or a gasketed insert to mate with the stock exhaust.
2. Seriously, pointing the second O2 sensor downwards? That was not a brilliant design idea. My brand new sensor was promptly destroyed at the first race. I had a shop weld in a new bung that points the sensor upwards so that it's not the lowest point on the car. I expected more for the price I paid.

Let me save you research that you are going to do for no reason on this product...
If you are looking at it right now, just BUY IT!
Amazing product, amazing quality, beautiful welds, and sounds WONDERFUL.

Amazing downpipe. The power gains are worth every cent. But I noticed I have a rubbing issue in between the cross member and the side wastegate tube.

Very amazing product! I had it hooked to my stock CBE, and it didn't effect the sound much, but oh boy my butt dyno felt it. Paired of with the CBE system, it will make you smile every time you get on the on ramp!

Great product once again from CorkSport. Installation is a breeze compared to how hard it is to get the stock down Down pipe out from the engine bay. I would highly recommend a set of tools that let the bolt pass through though as it is incredibly hard to reach behind the down pipe to tighten that last bolt. Overall great performance and a more aggressive exhaust note :).
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
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!).
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.
