Can someone link me to a vendor? Also, I see some downpipes with two tubes that dump into one, and some that are single tubes. Is there advantages to one or the other? Thanks for the help.

The PDE Downpipe is a single tube, aka bellmouth and It is my understanding that bellmouth is the way to go if you are going catless, it is also my understanding that the other type, refered to as twin dump is better if you are going to keep a cat in the system.

I have the PDE pipe on my car and in my opinion it is the absolute best pipe made, it is beutifull, the weld's are a work of art, you don't have to worry about throwing a CEL or buying a fix for it because the pipe has it's own fix built in. I definitly recommend it, you will be comfortable knowing that it is under your car. The only thing that you have to worry about now is what cat-back to match up to it.

P.S. I almost forgot to mention that my experiece with PDE customer service has been great.

 

i agree the pde dp is a very nice pipe welds and all as mentioned above. mine is on my sti it mated up to my hks carbon-ti perfect. noticeable power and tq increase along with sound. also kinda weird i havent had any boost creep issues either.
