From HFC to test pipes

Leuz · 09-23-2013, 02:19 PM

OP, when I ordered my HCF + CBE setup I started having your same doubts. Should I need to go with ART pipes or stay with HFC. I spent a month looking at videos, posts and specs and decided to stay with HFC for the following reasons:
- it's my DD and I prefer HFC over TP (mostly afraid of the smell)
- I wanted to go with the same manufacturer to couple HFC+CBE (as someone mentioned already)
Hope this helps making up you your mind.

To answer your question for the 3rd time in this thread. More hp with testpipe or more tq with hfc.

I guess I will add my two cents to the conversation as I am in agreement with Roy. I have a similar setup as the OP except I don't have an after market CAI. When considering all the options and not spending money where I didn't need too, I put my money into ART Pipes and M370 Manifold. I chased tq since the hp gains are not really usable unless running at the top end. If you look at others signature lines or treads they may get another 10whp but they will have almost that same number less in tq. Anyway, it really is about what makes you happy...that's why I decide to go FI and I'm sure there will be something else to want after that! LOL

Bolio is correct from what I've experienced

I paired up MD ART pipes with my FI exhaust today. There is no rasp and the sound is insanely beautiful. A great combination with no CEL light.

^^^ The ART's really bring out the beautiful nuances of the FI exhaust -- who am I kidding, it sounds fvcking great!

Lance, I prefer the test pipes, and I don't care about smell.. its not that bad. The only thing that bothers me is the hiss on decel through the lower rpm range. I can hear it even in the car. RHFC's would probably kill most/all of the hiss you can hear inside, though.

Riptide67 · 09-29-2013, 12:08 PM

I couldn't believe how amazing it sounded. I could barely keep off the throttle along with the install of the Stillen G3's.

I was a bit scared going back to test pipes with my prior experience of Invidia's on my 350Z. But, I am glad I got back on the TP wagon with ART pipes. One hell I an amazing bolt on for our cars.

Only time I can really hear the hiss is first and second gear, but I like it oddly. I can't hear it in the car at all unless I have the volume knob to zero.

I've elected to go with Resonated HFCs (had in my G37 and loved them). For the catback I went with a NONresonated Xpipe and SS canisters.

I've looked into MD, but just wouldn't consider it. Ran nothing but Fast Intentions on my G37, and not looking to change now. Only options for me were Resonated TPs or Resonated HFCs. The "pros & cons" of both, the HFCs came out on top. The midrange of TQ from 3500-5500 is higher in the HFCs, with the HP of the TP not surpassing the HFC until nearly 6k in the powerban.

What people don't realize is how much flow HFCs truly have.

Good choice...about people not realizing how much flow HFC's have...you're right....but to them I say...They're not called "High Flow Cats" for nothing....

I can't imagine having to store away my Z and not drive it....

That really sucks....Glad that we don't have those issues here on Guam..Get to drive the Z 365 days a year....

I don't know how you guys all do it back there during the winter time

....But then again I could imagine that it would be hard to

a Z in the winter...

I've owned a G35 5AT, a G37 6MT, and now my Nismo. The G35 was my daily driver right out of college, which I drove for 2 winters. It honestly wasn't that bad, and I didn't even have winter tires.

The main factor around storing my G37 and now my Nismo is avoiding the salt. It absolutely DESTROYS a car along w/ the goodies we install on it.
