Should I switch to DDP?

[JohnRardin]

I'm currently using a 3" elbow with an HKS DP but the opening on my DP is actually 2.5". Im concidering switching to the DDP but I want to be sure it's worth it. I found a DDP on ebay but its not actually a divorced DP since the wastegate pipe recirculates. The price is right but I'd like to hear what you guys think. Would the money be better invested elsewhere?

dp's with an integrated elbow are always said to be better. and since you have the bottle-necked hks dp right now i would think it would be a definite improvement. the whole recirculated part wouldn't be as noisy as the non. plus, if you get the ddp then i can take your 3" elbow off your hands. :biglaugh:

Yea man, you got it. It seems that I can get either DDP or RDP for the same price so I suppose I'll go for the DDP. Would there be any reason to go with the recirculated version?

The reason to get a recirculated version is noise. Recirculated is quieter than non, and it's equally powerful.

I got the recirculated one.
As for performance I couldnt be happier!

But fitment, DP to stock catback was no problems.
But when I installed my Tanabe SHM something was wrong...
The DP was about 30mm to short and the Tanabe was hitting the sharp turn at the diff.

The Dp was so well tucked up to the floor that I had to move the speedo cable.

Well worth the money but beware that it may not fit 100% out of the box.

I have a BIC Re-Routed DDP. I LOVE IT! :love: fitment is great, and the turbo spools faster. I couldn't be any happier unless I had an EBC. I sometimes hit fuel/boost cut I have all the additional add-ons on my DDP.

 

[natedogr]

like emilio said, the recirculated isn't nearly as loud so that would be a reason to get one. unless you liked how loud the open one is.

I bought a ZW DDP. Aside from an AVCR, it's one of the best, noticeable mods I've done to the car without upgrading turbo and fuel systems.

I personally went from the HKS DP to a rerouted DDP and I felt a noticeable difference. I would do it again given the same situation.

If I recall correctly, the Tanabe exhaust is the one that is the wrong length for non-california cars. Or something like that... it's a different length for some reason or other.

Nope, that's the Blitz Nur Spec...

 

[rtrdpenguin]

I stand corrected. I wonder why the Tanabe doesn't mate up to the DDP though...

 

[marc3]

seriously, any one ever wonder why hks made such a downpipe?

 

[Poodles]

Because it mounts up to the stock elbow quite well...

 

[WhtMa71]

Im not sure what kind of DP I have but it connects directly to my Blitz Nur Spec exhaust. Not even a space for a cat or test pipe. It has a flex section and the opening is 3".Im just guessing it's a Blitz DP. Works perfectly with my lipp elbow. It also bolted to the stock elbow quite well even with a 3" inlet.

 

[Poodles]

Sounds like the random tech. DP, cause I think it eliminates both cats...

I have this DDP

I cant be 100% sure that nothing is wrong with the Tanabe but its more likely the DDP beeing to short.

This is my car with only exhaust mods and a Blitz BC, nothing else.

Here's a short little in-car video. I didn't take it all the way to redline. I think I was shifting @ around 5500.
Exhaust Mods: BIC Re-Routed DDP, 935 MS Exhaust Piping, Megan M-GT Muffler.
It honestly sounds the same when i had the stock elbow/HKS DP on, just a tad louder. I don't like how loud and open wastegate sounds. I'm going to replace the exhaust with something a little bit quieter though.
