Nice work! What is the price for the complete package?

Matt (&/or others who have the system), I get the power hike, the weight loss but could we talk noise. Specifically could you compare to my current set up that is FVD Brombacher side muffler bypass, OEM center muffler and valves disconnected (vac hose removed and plugged). I like noise!! So when on the gas this system sounds great, they all do I guess just different tones. So question is how does it compare on start-up and running down the Main Street at 30'ish mph. I think I hear you saying from your video that it would be quieter than my current set-up as the valves would be closed and the center muffler would be suppressing noise? Do I have this right?
I'm not looking for full cup car race levels of sound but I think this car deserves noise!! Many thanks,

Matt, I remember you said you won't touch the header when I asked your the advice about getting the GMG header.

I've decided to let go my GMG exhaust setup after watching your not-very-pefrect (as u said of course) video. So.. What is your advice for me now? Shall I take my car to do the Dyno test first? or sell the GMG stuff straight away. FYI, my car has GMG header + OEM mid muffler + GMG center bypass.

The words in the video "definitely of significant difference of power output" really impressed me.

I'm in the half way to the Dundon exhaust. I think you shall refund some credits back to Matt. His exhaust review really impress people who want to upgrade their exhaust.

I'm curious : is there a reason why you've placed the downstream almost in line with the upstream ?
I know the cat core is just a few mm wide,so Porsche usually places the O2s relatively close to each other,but I'm wondering why you've place them almost in-line...
Wouldn't it be beneficial if you got the O2s away from each other and then you can use a shorter extender? Or is it because the O2 wire harness is too short?

As always great work and well documented. Thanks!

Does it sound much deeper than a center or side delete? From the video, it has a nice deep growl to it which I like. I currently have the Sharkwerks and it doesn't sound very deep so I'm in search for a better sounding exhaust.

I went from SW center bypass to FVD side bypass to get a deep, louder sound. SW sounds great >4000 rpm but I want nasty thru the entire rev range!! Couldn't make out from the video if this does what I want hence a request to compare the two as I know Matt has done the FVD bypass as well.

Jamie Have you tried the Sharkwerks center bypass with this system and how does it sound?

AKA no mufflers whatsoever? :P

What mechanically makes the transition from closed to open, on the flaps, better? Are the parts the same? To me no cats is a big risk both legally and from a warranty standpoint. Especially with the E and F engine issues. On balance, sounds very good and power increase is good too. We all know nothing is free. Thanks for the review. Best, Allan

Mech, Yeah thats what I thought, we will need more than your LS cheater..lol

I like your questions Allen. I also notice the Dundon system is a de-cat system. I wonder to know what make the car so civilized while cruising with no drone. To my knowledge, no cat means loud and drone. I m speaking based on my experience. Also the valves, Matt said in the video the valve transaction has been much much more improved. What is the magic to make it happen? Does it work the same way as the factory valves? Open and close at certain rpm? Is the sport exhaust button still functioning?

Cheers
