350Z Sound Difference: Motordyne ART Pipes

My full review of the ART Pipes here:
www.my350z.com/forum/intake-exhaust/476102-independent-review-motordyne-art-pipe­s.html

Solid gains throughout the entire performance band. Approximately 9whp and 5wtq at the top end. I actually gained as much as 23wtq at 2800rpm, which is enormous.

2006 350Z (6MT w/ RevUp Engine)
Mods before:
K&N Drop In Filter
Motordyne 5/16" Spacer
Motordyne MREV2
Stillen Headers
Stillen HFCs (Replaced with ART Pipes here)
Stillen True Dual Exhaust
Uprev Tuned (w/ stock headers)

why didnt you get the motordyne exhaust?

@11aamiller

Well, at the time of this video, it was a matter of money. That and my Stillen was working just fine. However, I actually DID end up getting the Motordyne TDX V2 Exhaust. In fact, I was one of the very first to pick that one up. I have a whole other video dedicated to that if you want to check it out.

Question, how did you make gains? I understand you had it dyno'd and have proof. I would just like an explanation b/c from what I understood, headers + HFC's + catback = no back end pressure.

I am by no means arguing, just curious. One reason as to why I'm so curious is b/c I am thinking about putting headers on my G to compliment my FI HFC's.. But I'm worried if I upgrade my catback system along with headers I wont have enough back end pressure.

@socboy001

I understand what you're saying. However, I wouldn't get too wrapped up in the back-pressure issue. While I don't claim to fully understand it, I can certainly tell you that just because you open it up doesn't mean there is no more pressure. Depending on the car and depending on the mods, the pressure difference can be played with a great deal. You'll be fine with a full header-back exhaust. People do it all the time.

I just put my Stillen headers up for sale, if you're interested.

@cbeck611

They're essentially advanced straight pipes. While typical straight pipes simply replace the catalytic converters with simple pipes (i.e. absolutely no resistance or emissions control), these have specially tuned Helmholtz resonance chambers built into them to 1) eliminate unwanted frequencies that cause rasp or droning in the exhaust note and 2) actually help the exhaust flow, giving you more power and torque than either any set of High Flow Cats or Straight Pipes.

@oNAGAo what are the ART pipes and what do they do for you

@MrOblivion582

I'm actually not sure. I did dyno after the headers, but I think there was some other issue with the car that was causing a drop in power. Either that or the original dyno was recalibrated. But after I did a before/after dyno for removing the headers, it showed that they had given me about 11whp at around 6600 rpm. The numbers that Stillen advertised were actually spot-on. So to answer your question in a roundabout way, yeah, it should have put me in the 280's.

@pfregeolle

As I said before, the difference is very hard to notice from just a Youtube video. In actuality there was a significant difference.

[pfregeolle]

Sounds no different, just more hiss from the lack of backpressure.
