Berk Street Exhaust Axle back

Hey everyone,
I purchased a Berk Axle-Back from a member here a while back and just had it installed two weekends ago. The shop that installed it said there was some sort of back pressure valve at the back of the exhaust system and said he plugged it. I had my 1 year old with me and didn't have time to ask many questions, but it's been in the back of my mind ever since. Is anyone familiar with some type of valve at the back portion of the exhaust, and would you need to plug it when replacing the stock muffler with an aftermarket axle-back?

Thanks is advance!

Yea. It's the valve that opens and closes one of the outlets on the stock exhaust at low RPMs. He did the golf tee trick so dirt doesn't get inside the tube

Awesome, ty. I was watching B is for Build and he thought he had one of these but it ended up being an EGR valve or something, Tee'd off would have been bad news, got me paranoid.

Berk street axle back is very mild if anyone stumbles across this btw, sounds great on cold start but then is pretty flat, no extra sound really on the top end, which is all I wanted, and is a bit drone-y.

I went stage 1 MHD and the sound is ubelievable. Sounds like a legit performance car, very racy.

I will definitely be doing RSRR's, downpipes (catted), a 5" FMIC (not cool with cutting) and MHD stage 2 this summer.
