I've listened closely at all RPM's and throttle positions and I've never heard a whooosh sound but I do know exhaust parts can sound (or interact) differently on different exhaust setups.

 

Hmmm, I have a Borla TD with a Magnaflow X-pipe. Curious if anyone else with a Borla has these and hears the same thing.

 

There are a few points at which I can sort of hear a bit of what sounds like little more than air flowing through pipes under light throttle (accompanied by the rest of the exhaust music). However, I wouldn't describe it as a "whoosh" by any means. Honestly, I've chalked it up to being frequency cancellation within the exhaust note, because these points are where there was previously a fair amount of nasty rasp and other noise of that kind. In any case, the sound is neither very noticeable nor undesirable, but probably just a function of the interaction with whatever specific setup one is running with.

 

Hey Tony, have you got any sound/video clips of your Z? I'm sure everyone here would love to hear/see the full MD bolt-on setup and specs on what you're running

 

Oh, don't worry, I actually quite like whatever noise I hear. Hahaha. It sounds rather nice.

 

Sorry, I don't have clips with the ART pipes on my Z.

Besides... there are 100+ variations of exhaust configurations possible. Which to do?

I like the Shockwave single because its so incredibly loud. I like the dual V2 because it has the really deep sound. Sometimes the VQ. And then there are the prototypes... Its always changing.

 

Tony, any update on when these will be available for HR owners?

 

My fabrication shop is moving to a new facility this week. After they get straightened out in the new place I'll get the HR and VHR parts into production. I estimate ~3 weeks.

 

cant wait

 

Anymore test pipe comparisons? I only found one. My friend is adamant about these not making any more power than a test pipe.

 

^^im still waiting myself for another comparison...As the one i saw didnt do anything for me..

 

Getting my car re-tuned with the ART pipes next week, and will update the results I previously posted.

 

Very interested in your results since you don't have headers.

 

Same here. I wonder if it'll be worth re-tuning.

 

I've changed the entire exhaust geometry: ID, transitions, bend locations, etc. A tune is a must for me.

 

about to pull the trigger i think!

p.s. nice article in Import Tuner mag on these

 

Tony makes fantastic products for our cars.

Just waiting on the non-polished version.......

 

unpolished for me please!

 

Scott,

I should have thought of this previously. It would make a great comparison in addition to your current testing.

When you switched from cats to ART pipes it made good gains... this is to be expected.

You also have the resonated XYZ pipe on your Z correct? ...It would be good to see how your car would now perform with the XYZ HFC installed.

The XYZ HFC drops ~4 HP from either the XYZ resonator or straight pipe. It would be interesting to see a comparison of your old HFC's power curve Vs the XYZ HFC with ART pipes.

Both set up's would be with HFC's but now it would be a direct comparison of the Motordyne HFC setup Vs your prior HFC's.

Is this something you could do on the dyno?

 

Tony,
Yes, cats to ART pipes = gain as expected. Check
I do have the resonated XYZ pipe on now, and could test the XYZ HFC as well, however, I never had other HFCs, just OEM cats, 2" open TPs, and now your ART pipes, so if we did a MD HFC in place of my resonated XYZ pipe, we could only compare it to OEM cats and the previous ABC 2" test pipes. If that makes sense, we could do that on the dyno this week.
