Your non dumped exhaust seems to have all of these, which is attributing to a larger gain when the dump actually opens. Not trying to bash the work (which is beautiful) but it is probably easier and cheaper for most people to use a run of the mill 3" exhaust and test pipe, unless you are having trouble with coppers, in that case this is an awesome system. Even a 3" exhaust will certainly have more restriction that this design. But that’s really not important. The point was not to find a cheap option, the point was to build a system that had the very best of both Worlds. With the dump closed, the car idles as quitely as a stock Honda Accord. Cruising the car is almost inaudible, perfect for having a conversation or listening to tunes. Open, the car transforms into a race car, loud, responsive and obnoxious. The value in this system is not the cost or that there are cheaper alternatives. The fact that I can have two different cars and switch between then in lest than two seconds from the push of a button was the experiment…and the dyno is proof positive that it has worked. --- _[View the full topic](https://forums.speedlife.net/t/dr-jekyll-exhaust-works-well-on-new-setup/119909)._
