I think I have seen something like this for hondas, by mugen. I think my friend has a mugen twin loop on his hatch. makes it pretty quiet and supposedly more free flowin? but yea thats just generic brand for sure

I wouldn't dream of replacing my Cobb exhaust with that POS.

It's a gimmick. Two 180-degree bends in an exhaust system does not flow more than straight-through design. Dead weight. More back pressure does not make more power if engine is tuned correctly.

The "backpressure == power" myth is pretty common on NA cars. On a turbo car, the more free flowing the exhaust is, the better.

It's ok to run that as long as the first pathway through is separate from the 2nd time. (two different resonance chambers).

That right there is like having two mufflers, it's way to get that kind of quiet exhaust without taking up much space.

As long as the bends are smooth and internally that muffler has two separate passage ways, you won't lose power. 2.5" is not ideal though for a WRX/STi.

+1 and +2 for people who know what they're talking about!

For all the other morons who are calling it a POS, why are you saying it's a POS when you have no idea what it is.

How can a muffler that cost 31 bucks on e-bay be of any quality?

Agreed. The concept is sound (no pun intended) but this specific product has got to be a joke.
