I'm considering changing my exhaust gaskets to see if it helps with the sputtering I am getting when I decell. Does anyone have the part # for a replacement gasket for a 2007 Dyna Twin Cam
Do all I need to replace is the gasket or should the clamp be replaced also.
Currently running V&H Bid Radius W/PCIII and Arlen Ness Big Sucker
I have been getting this sputtering ever since I had the stage 1 installed by the dealer. I have been back twice and they tweeked the PCIII but I still get this sputtering. Is there an easy way I can check if I have a leak at the exhaust/engine

as far as the gaskets you can go with stock which are big and somtimes can parially block your exhaust, but provide a good seal and are easier to install. the other choice would be Screaming Eagle performance type. these are smaller and less forgiving when installed. i believe that most people prefer the later. they cost about $8.00. when it comes to clamps we're likely talking about at the muffler/header joint. this is where you're likely to be leaking. first thing to do would be get rid of the V/H clamp and go back to the HD clamp which is by far superior. before doing anything more to your map make sure you don't have any leaking, otherwise you'll be running in circles. good luck and be patient. you'll win

on checking for leaks. try lightly obstructing the exhaust by partially covering it with a wet rag. this will make it leak worse so it will be easier to detect.
