Ill be posting more footage of the kline car, as well as different configurations of bc fabs on my car. Inconel rear +/- steel power pack (the rest). Hold your horses.
ps the valves open on the kline is about 50% louder than a stock gt3 (outside). It sounds bad *** but it will hurt someones ears for sure. Just an honest reference. I will do dB measurements on all configs. The bc full system should blow a hole in your brain. But i suspect the rear pipe is gonna be sweet
ps valves closed the kline is very stock like (stock +). Thats the experience ive had with all their systems. All the combos mentioned above should be great but it depends what you want. They all sound the same on camera.

JCR pricing is totally outrageous... and they are completely unapologetic! I guess if you can get away with it, then why not.

The kline is real good. If u want the sound from the videos though you have to run a valve controller wide open. It makes a big difference otherwise you are running through 3 mufflers. The reason it has 0 drone is because it always runs through those side cans even if it goes in the top path its got corrugated piping in there and draws flow into the resonators for collisions at the merged paths. That said, with the valves disconnected its another level of loud. Its not like an exhaust on a turbo car

So, if we use the stock valve control with PSE on, it's quiet until 4000 rpm when it opens up to that glorious sound? And when PSE off, it's quiet all the way through?

never heard it with stock valve transition but its a big step change from valves closed to open on the outside. I have heard valves closed 100% of the time and valves open 100% of the time. Thats how it was installed on this particular car. Valves closed is like stock plus noise level but more clear. Valves open is race car volume.

Race car volume like JCR full exhaust volume or Soul's full exhaust volume, or Cargraphic's Full exhaust volume?
