Eh, I'd say on a DE and with my setup I wouldn't notice too much of a difference. Now, maybe paired with a boosted setup and/or cams I would see a different result with long tubes.

Ah, good point I didn't think about that. Z1 actually got the old momentum headers jig. They're pretty much identical with different branding (don't quote me on that). Fitment and overall runner length should be the same.

Yeah, it seems to be the trend that guys are claiming things without much solid proof to back it up. I've done all my own independent dyno testing.
I think it was around $200 when all was said and done for the ceramic coating from NitroPlate. Coating was done on the inside and the outside. Holds a beautiful shine and those guys are top notch to work with. Fast turn around and high quality.
If you call, ask for Cody and use me as a reference.

Ok so I swapped out the HFCs for the test pipes and put in the MotorDyne Ypipe with Resonator. First impressions the design of the Motordyne pipe looks like it just plain flows better. Ill let the pics speak for itself.
Now for the sound you really are going to want to keep the HFCs in with this setup if you daily drive it. Test pipes add some volume. The note of the exhaust definitely changed with the resonated section in the Ypipe. Its a bit deeper. Still too loud for my taste but again the test pipes are really causing the bulk of the volume increase. Definitely a lot less rasp tho from the ypipe switch. I may be throwing in the towel on the Tomei exhaust I regret and going with an Stune midpipe and muffler tho. We will see.

The more I think about long tube headers, and talk with other people about it... the more I think PPE LTH are a waste of money. Think about it this way:
If you're spending over a thousand dollars for long tube headers, you're dedicated with deep pockets. If you don't put cams in the car, you're wasting your money. And THEN, if you put cams in the car with some off the shelf generic LTH design, it's not going to be engineered for your specific cams with all of their unique valve opening, closing, overlapping ****. It wont match, wont be optimal, and wont necessarily make power. Just like everyone already knows, from the intake to the exhaust everything works together, and has to be perfectly matched for OPTIMUM performance.
I think, if you're doing LTH, you need to get a mad scientist to design it around your specific engine.

I caved in and bought the full tomei system and some resonated tp's. I am about to drop the subframe for a bushing overhaul so it'll be awhile before I post a sound clip. In the end I opted for the tomei as the only difference in the soho system was the tapered section in the ypipe. Both setups cost the same amount so I opted for the tomei (titanium) over the soho setup which is generic piping and vibrant can (couldnt justify the price).
Thanks for all the opinions and feedback in this thread! I'll post a video down the road when its all back together.

Also the stock headers are FAR from optimal. Simply put, I do not see the point of what you're trying to convey. Sure it may not be at its peak efficiency, but I can surely argue its closer than when I started. Find me evidence of the Ultimate design and I can guarantee I will be able to bury you in mountains of theory, estimations, and CFD data that would say otherwise.
Note I do not disagree that everything must "Work Together" but I def. do not comprehend your logic behind why you deem it a "waste". Technically speaking having a car more than a golf cart is a waste.
Back on topic- I notice when i switched from HFC to PPE, on my JIC Ti, I didnt notice any difference in overall volume. Tone changed at certain RPMS though.
Edit- I personally love Ti exhausts, I'd hang that y-pipe on the wall if I were you. Also is that a bung at the end of the Tomei y-pipe? Also, Cool build btw mcarther

I dont see the point of paying XXX dollars for just ART pipes. Considering most of the guys (the vocal ones anyway) picked up the PPE headers for under a grand, myself included, It actually is not that much more expensive.

Thanks, ya I guess after hearing from 1cockyz how he lost power going from DC headers + TPs to PPE LTH I just don't see the advantage in that particular design vs shorties + TPs. I think if I were to go LTH, it would have to be a 1 off design for my engine otherwise I'd always wonder if it was really worth it in the back of my mind.

So I installed the Motordyne XYZ with Resonator, Tomei Expreme exhaust. I already have stock headers and ART pipes. Now I previously had a Motordyne TDX v2, which I still love, the tomei does drone a small bit; BUT! the tone is amazing! The extra volume is well worth it. I love the sound this produces.
