Wonder how it'll help rasp with a dp tho

Theres several videos in this thread and on valvetronics YouTube page that show how it sounds within stock, 200cell, and catless dps. Zero rasp.

+1 interested in another group buy after hearing this in person

I just got my shipping notification as well - ordered a pretty long time ago but should be here saturday. I'll try to grab some video assuming it gets here early enough in the day for me to install.

I'm running stock intakes, fat boy 3.5" catless downpipes w/ Mosselman turbos so it'll be interesting to hear how the exhaust sounds like with a larger turbo setup.

Thanks. I ordered mine yesterday and it looks like they have product in hand ready to ship!

It sounds awesome but for whatever reason the idea of sending exhaust either left or right with the valve makes me bummed. Gonna stick with what I’ve got for now but maybe someone can help me understand why that doesn’t matter.

Less length to travel with open valves seems better to me. I need to do more research though.

Yup deals too good. Had to pull the trigger. Hopefully the lead time isn't insane.

cotmfk · 11-27-2023, 02:25 PM

Just got shipping confirmation - super excited to get this on and get rid of the lawnmower sound.

All the videos do a good job of demonstrating the sound at full throttle with the valves open and above 5k RPM.
There is almost no mention of valves closed regular daily driving, the most I've seen was valves closed cold start.

I'm worried I am going to regret the decision if its too loud for normal daily driving...

As quiet as my stock competition exhaust was with valves closed/efficient mode, but with a noticeably improved tone. You don’t have to worry about that at all.

You will have a much louder cold start though unless you use their valves and valve controller to force valves closed on start up. you can also turn cold start off with a coding program if you want to use your stock valves.

It’s definitely worth it though

Thanks for the response!
Do you have the stainless steel or titanium version?
I already have the cold start turned off through BM3 as I am running catless downpipes so nothing there to warm..
