Uff... I had understood that there was not so much drone... trade off between SE and 70 EM, still remain...

 

The 70em dual does drone while the greddy was way better. Build quality was better with the greedy as well.

 

I'm about to get the 70em single and run it with flashpro. I was under the impression it was fairly quiet and did not drone.

 

Greddy SE Dual here with FlashPro. Let me tell you, with the 70mm Berk TP and no FlashPro, it sounded great with a hint of rasp from 6k to redline. Now with FlashPro and Toda-tune, it's deeper all the way through with no rasp. I love it!

 

Ditto

 

Q300, Flashpro, 70mm Berk HFC, stock header, and Fujita CAI here. I installed the Q300 and HFC at the same time. I felt a very significant improvement in the midrange and think there was a small gain in peak power. I don't have dyno results to prove or quantify it, so take it FWIW.

As for the sound of it, I really like it. It's got plenty of volume but isn't obnoxious by any stretch. The intake is louder than the exhaust at high RPMs, and it's got some boom at ~2.5-4k that disappears above that. I get a lot of compliments on the sound of the car at the track here, but I also don't draw unwanted attention or frustration from neighbors.

The Q300 build quality is decent but I don't like the idea of slip fit as well as a longer bent pipe. The price is excellent for the product you're getting.

 

I have the Fuji on my one s2000 and the Tanabe Touring dual on my other s2000.

I can tell you the Tanabe is definitely louder but visually it does look better than the Fuji. Both are well constructed exhaust setups.

Planning to conduct some tests on which one is better in the upcoming month

 

You will see gains with an HFC or matching test pipe. I would go with AT LEAST a 70mm if not a 3 inch. 3 inch with a 3 inch HFC would be nice and a fpro tune
