I love how my Ansa sounds, but I have never been happy with the way the OEM tips look, tacked onto the back of the muffler. They aren't totally straight, and the old rings still exist from where the much larger Ansa tips once rested.
Also, I'm not convinced that the Ansa flows any more than the OEM... it's louder, but the design is an inlet into an open cavity, two resonating pipes, and another void before exiting. Not to mention, due to the length of the Ansa, there is a sharp 90° elbow before the inlet.
With the Dynomax VT, they have an offset inlet (same as OEM) with a single center exit. I'm going to utilize the tip that James found (Wicked Flow) and see what happens. The VT series is supposed to have no drone, low noise under light load, but roar at WOT and flow much more than the Ansa.
The version I plan to use is the 17156 (shown above)
Sound at WOT should be comparable to the Megan Racing twin muffler, as flow will be unimpeded.
Sounds interesting...
I have the Megan Racing muffler on my base coupe and the only thing I don't like about it is that it has a Y split and so the dude that put it on for me had to bend a piece of pipe to get it to fit (which I think I can attribute the occasional popping sound when downshifting at low speeds).
The valve thing they designed seems like a cool idea... I notice a lot of drone from the Megan Racing muffler (mostly at low RPM or around freeway speeds of ~60-70 mph in 6th gear) so it would be cool if that could be eliminated...but if you've seen my gallery... you know that I can't hear $h!t when I turn my stereo up so that's not really an issue for me.
My question to you is... how much does it cost to be the guinea pig..
