Great article in the best mag out there.

For those of us without the magazine available, which one came out on top per their review?

Can I pick this up at Walmart?

Looks like a very exhaustive (pun intended) review as this represents a MOUNTAIN of work and appears they analyzed it every way they could, however isn't this like marketing pornography for the blind? Hearing the tone of an exhaust is one of, if not the biggest, selling points of replacing the stock system. The should have had a "preview" on their webpage so subscribers could get a better feel for each system.

+1

A friend had the mag and I flipped through.. I forgot who had the most power.. But if I'm not mistaken the greddy evo3 was by far the loudest.. I think that's what they said.. I seen the video of the greddy off of greddy's Facebook page and they had a lot of sound recordings at different rom levels.. By far not a simple test with all the exhausts

Let me know when you get any information at all instead of just posting a link with whats included in the magazine...

Perrin and Isis did best in power gains across the whole rpm range for non-muffler deletes.

Edit: Perrin Un-resonated.

Which were the competitors?

Agency Power (lightest)
Berk Technology
Greddy
HKS
Isis
Magnaflow
MXP (Mackin eXtreme Products, prototype, heavier than stock)
Perrin (resonated and un, unit was better)
ASR muffler delete
Berk track pipe (highest peak power)

Sounds like only companies that had products in stock when they wanted to test were used.

Mag is one with the DVD, and model is Harmony Vu, if anyone's interested.

do they have digital issues or just hard copies?

How did the HKS fare?

Quietest, made a bit of power (all were actually pretty close), only 2lbs lighter than stock, and most expensive.

This was their Legamax model.
