Hello all,

I am in the process of setting up a MCDA on some exhaust systems, but I need help quantifying some of the subjective qualities of the systems.

I have done a lot of research to find information such as best price, weight vs stock, etc. But the things that don't have a hard number are things including sound and appearance.

Where I need the help of you guys is putting a number to two of the sound features; overall volume, tone, and resonance (drone).

I would like you to rate the following systems (those that have experience with them):

1. Greddy SP Elite/SP2
2. Tanabe Medalion Touring (System is discontinued but a few are still lingering around)
3. Fujitsubo Legalis R

For the volume & tone, please rate on a scale of 1-10, 10 being the best.
Personal Note: What I consider "best" is fairly quiet (relevant to aftermarket systems), and deep

For resonance, please rate on a scale of 0-1, 0 being virtually no resonance, 1 being significant resonance.

If it is helpful, please compare these to other well known systems. For example, the REV 8 I would probably rate as a 9 for volume, 10 for tone, and a 0 for drone since it is the most mild system on the market.

Anything you can contribute would be greatly appreciated!

 

Sorry if this is on a bit of a tangent...

I run a REV8 and I've tried it with a straight mid pipe and now I'm running it with a high flow cat and no resonator.
It is remarkable how loud the REV8 can get with no cat or resonator...
With the high flow cat I really like its tone and volume.

 

You bring up a good point that I forgot about.

I am asking specifically about the catback's alone. Not paired with a midpipe/resonated pipe/high flow cat. Just the catbacks and the stock cat.

However, if your experiences are only with the exhaust and a stock cat-replacement pipe, please give your best guess as to what just the exhaust would be.
