Bolt on to replace the OEM perfectly and easily. I am having a jig made so I can replicate it for anyone who would like one.

My Borlas on the 135 were straight pipes, very similar to these, and I loved the sound and power gains. They however wont bolt right in and up to the stock muffler... or in my case potentially an Akra slip on.
