Very nice!

Mine has been sitting in my garage all winter. Just need to wait for one glorious weather day to install it on my car.

Exhaust bypass, interested to learn more as this upgrade is usually reserved for Ferrari owners and forums.

Did the Sharkwerks Center Bypass on my Touring. Best decision ever. Don't wait... just do it!

So many familiar faces in here haha. Thanks for all the kind words and interested guys : ) Here are some more clips of our Center Muffler Bypass in action. I'm working on putting up a separate thread on our new Modular Competition System as well.

Re-installed the stock side mufflers and replaced the stock center with the SOUL center muffler. Really, really like the sound this way. No drone, deeper note than the stock muffler with the side muffler bypass pipes. Very Happy with the muffler!

PSE valves active or disconnected?

They PSE valves are active. I need to drive the car a bit more to get an idea of what I'm "missing" with the valves connected. For now, I thought it sounded great. A good compromise for those of use who don't want the car to sound like a bat outta hell at all times.

Before it used to sound like metallica... all the time. Now, it's deeper and really starts to wail after 4k and it actually sounds pretty good even with the valves closed.

Overall, I just like the tone better. The side muffler bypass pipes with stock muffler sounded too metallic for me.

Thanks for info. The reason for asking is, I'm very interested in a CMD but I would also like to keep the PSE valves open all the time, over the whole rev range, to avoid the "step"/increase in sound at 4000. But I definitely do not want to run into drone at sub 4000rpms...

Yeah, I can totally sympathize with that. It was a interesting change, going back to the step/increase in sound from the no-valve, bypass pipe. I'll have to drive it a bit more to see if it really gets to me.

Here she is, internals showing...

vakves open all the time via plugging the solenoids causes a drop in torque.

Something about those OEM side mufflers really bugs me.

I’ll be doing sides plus center so the sound would have to be pretty unpleasant for me to put the OEM sides back on.
