I recently had the victory stage 1 shotgun pipes installed on my '06 Hammer, love the difference it made in looks and sound. But...I'm interested in removing the baffles to increase the sound even more. Does anyone have any ideas or suggestions as far as if this is a good idea or not? The tech that put the pipes on said the only thing he was unsure of is how it would actually sound, and if they would have to change any internal settings?

no baffles equal no back pressure, this isn't good for the engine.

Thanks for the reply!
I heard the same thing from a maintenance tech, but he added that if the baffles are removed, the system might have to be adjusted again, just like they did when they put the shotgun pipes on. I guess I'm debating if it's feasible to take the baffles out but then have it "retuned" so to speak. Are you saying that engine damage could result no matter what?
Thanks again for your input.

the way it was explained to me is that with no exhaust back pressure you'll burn your valves up.
i don't think remapping would help with back pressure.

It will reduce the level of backpressure, but there will still be some. The whole burning up valves is a potential issue, however, this is more a carryover from the good 'ole days than anything else.

If you pulled the baffles completely out, you would probably need to get a re-map. However, straight pipes on a Victory just don't sound good in my opinion. If you want more sound without a re-map, you could cut the baffle down a few inches, and reinstall it. To pull it from the pipe, you will need to get a set of post-in (also called 'tamper proof' or 'security') Torx drivers. I know both Sears and Lowes carry them, and most auto parts stores probably do too.
