Challenge Street X-Pipe install with Akra Slip-On at Benchmade Proper in Elkridge, MD

Challenge Street X-Pipe install at Benchmade Proper in Elkridge, MD. It is about an hour away and well worth the drive. Joe and Brian took their time installing my x-pipe. The attention to detail they displayed provided much needed comfort. It took about two hours for the complete install. Joe and Brian were down to earth peeps. We talked about cars the entire time. I will definitely be bringing my other cars here for additional fabrication work.

The Akrapovic Slip-On + Challenge Street x-pipe sounds much more aggressive than the Slip-On/OEM setup. I noticed minimal to no drone below 3k rpm. However, cold start is louder than the already loud Akra with OEM mid-pipe. Neighbors not going to be very happy.

Overall: More aggressive than Slip-On alone and not obnoxiously loud.
