After the cam install the exhaust noise got too loud.
With alot of resonates ,vibration in the floor boards. I have Tri Y Thorley Headers with a strait through Jardine muffler.
I have 16" of room in my stock pipe between the collector and the muffler to add a resonator. Has any one tried that ?
Looking at Vibrant bullet type or ultra quiet resonators.

Yup, I take it hunting. It wasn't the loudness but the resonation around 1500 RMPs that bugged me.Originally Posted by txarkitekt
I had a local muffler shop order and install a 3" ID 12" long bullet type glass pack with truncated swirlys inside. Put it between the cross members. It worked, took the resonation out. Floor boards do not vibrate any more.
