Our Street system achieves the same gains as race and comes pretty close to sounding the same. Check out our website for dyno's etc...

And some videos of an RS in the Georgia Mountains!

If the banks don't have ample space for waves to cross over there is a loss of power. A normally aspirated engine exhaust is more about resonance and wave strength than flow (all modern exhausts flow pretty well). A turbo exhaust is all about reducing turbo back pressure, so essentially no exhaust is the best exhaust for a turbo. The catbacks are way more about sound increase and weight loss.

When you are referring to the banks not having ample space for the waves and resonance wave strength, are you referring to headers? From my understanding once the exhaust gases exit the cats, not much affects the power. Whether you run a straight pipe or X-pipe bypass there should be less than a few hp difference. So when determining which catback to purchase we should just focus on sound, weight and build quality? Thanks for the technical advice. Now pleas give us a %20 percent off coupon for dundon race headers😜

How many flights in a year do you fly?

Ever flown on a private jet?

What an extraordinarily foolish set of statements for you to make.

Look at BBI. It's the same piece and the video on the BBI website is on and R. In fact, it's on Rahal's R.

I merely try to make people think for themselves.

I remember GMG releasing their exhaust for the 997 GT3. How many years ago is that ? Nothing new here
