PDE's Solid Uppipes are also available - same quality construction as the flex model - now CERAMIC COATED to minimize underhood heat!

This downpipe is the ideal solution for those that compete in autocrossing, track days, drag racing - you name it! Notice the beautifully done (and very strong) TIG welds, the 6-bolt cat flanges, the copper gaskets, the high-flow Random Technology metal substrate race cat (measures 3" long by 4" wide), the INCLUDED catless section, the ideally sized bellmouth, the perfect fit, the mechanical catless inefficiency CEL fix, the provision for the stock donut gasket.... shall I continue or let the pictures speak for themselves???

Sorry, they do not come with new gaskets - I wasn't able to get a competitive price on them. There are some reputable Subaru OEM part shops that sell them for great prices - I recommend OEM gaskets if you choose to replace them.


I am shipping out free Gorilla lug nuts though for a limited time! Thanks for posting!

The best way to answer this is "it depends". In many states they may pass the sniffer, but in states like California, they will not pass the visual test. If your state only requires an OBD scan, then it will pass because they will not trip a check-engine light.

That would probably depend on your tuning - it would be much less likely than catless.

Is the wastegate divorced? At the back of the DP is looks like it, but at the mouth it looks like the wastegate is blocked off.

Sorry I missed this question - the mouth of the PDE downpipe is sized to completely uncover the wastegate. The wastegate isn't blocked at all - PDE found this gave the best boost response without spikes, and overall performance. Also, the rear of the downpipe has a segregated O2 sensor pipe - this is PDE's innovation to avoid catalyst inefficiency check-engine lights.

how much does the pde downpipe increase cabin noise. As opposed to the few downpipes on the market that contain a cast bellmouth section??

IMO it is a pretty minimal increase in noise - especially if you have a quiet muffler. You can hear the turbo spinning up a bit more than versus the stock downpipe, but it isn't obtrusive in any way. Hopefully we can have some other PDE users add their thoughts on this.

Thanks!

I have the PDE ultimate downpipe w/removable race cat and the increase in noise is not much if at all. I have the Prodive catback muffler and all I hear when I hit the gas is the engine reving.

wi11,

PDE downpipes will fit with any USDM cat-back. If I recall correctly, the Blitz is designed for the factory donut gasket so the fitment will be absolutely perfect.

I think the bottle-neck issues you are referring to are when a flat-gasket DP is matched with a donut gasket cat-back. The cat-back necks down while the DP doesn't. Good fitment is an issue in this case, especially if the manufacturers aren't too great at keeping their tolerances in check. I can tell you that although the PDE necks down to accommodate the donut gasket (or it can accept a flat gasket), the differences on a dyno are minimal if at all.

I apologize but I do not stock cat-backs...I will probably stock the PDE cat-back when it is completed but there isn't a set due date on that.

The PDE downpipe design necks down to about 2.25" at the end of the downpipe for a very short distance...probably 2/3". What this does is allow you to utilize the stock donut gasket which does a couple of things:
1) keeps a flex in the exhaust
2) virtually guarantees a leak free fit
3) fits with ANY stock or US market cat-back (some of the JDM cat-backs are a different length)

PDE's testing showed they didn't lose a measurable amount of horsepower on the dyno and felt the benefits of this design far outweighed the possible costs - otherwise they wouldn't have done it!

Please keep the questions coming!

Wow, SpeedAbsolute and Duffman, Thank you very much for your responses. I am getting very tempted. I currently have a Cobb Downpipe on order and quite franky I'm getting sick of waiting so long, I've been waiting since early march. I would greatly appreciate if anyone else could add to my previous message.

Thanks,

-Zach

so where the blitz exhuast hooks up to the PDE downpipe the piping there is 2.25 " because i thought that the blitz exhuast was full 3" all the way?
-_- thanks
