Just installed the berk hfcs and couldnt be happier. Install went smoothly and only snapped one bolt. The sound is beautiful and not raspy at all. Definitely more throaty and the car already feels like its breathing significantly better. Overall a great mod at a great price.
One thing that does concern me though is at start up it is CRAZY loud! To the point where the interior panels shake and almost forces me to shut off the engine. Any ideas?? Goes away after 2-3 minutes and sounds normal after that. Only at start up. Smells like its slightly burning too. Any advice is appreciated.
