New Exhaust for my EG, it's bigger and quieter and makes more power
Well I thought I was finshed doing stuff to my "econo" build D16, https://honda-tech.com/zerothread?id=1716907, but it was just too loud for these old ears.
The old exhaust was a Greddy 60mm B pipe with the bottle neck removed, 60mm over the axle tubing into a 2-1/2" 5x8 Magnaflow. At around 4600 it just got so raspy I thought I was going to get pulled over. So I built a new system yesterday. I'm still running my prototype D16 header into a 2-1/4" 300 cell cat. I then went with 2-1/2" tubing into a 22" resonator, then into a short 9-10" resonator that I custom built to go along side the gas tank and finally into a double offset 6" round Magnaflow muffler.
SGT wanted to try running the Crome software so he made the swap and we were off making pulls.
Here's the results, Run3 was today and Run13 was from the last dyno session. CFs were 1.00 for both runs and it's the same dyno.
Almost 118 lb-ft from the little D16.
Here's a video of the exhaust:

UBERquiet hope mine sounds that quiet when I do mine, I'll be using a magnaflow highflow cat(with a test pipe for dynoing/race events), 22" magnaflow resonator and the SNL twin loop all with mandrel 2.5" piping.

UBERquiet? to me it still has the typical bumble bee in a coffe can sound in what sounds like post 4500 RPM range. Before that it sounds nice, deep, then it gets all off a sudden louder and all raspy, which is why i think i'll be running stock exhaust no matter waht i do to the car, to me, civics just sound like ****...
