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! |

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. Thread can be closed. |

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