Has anyone de-baffled their Valk? I'm thinking about it but am worried I will need to adjust the carbs?
Thoughts?
Thanks,
Dan

On my past Interstate, I drilled all the baffles through. Did not need to re-jet. Bile always ran great.

If you're going to drill them, start with a small bit and see how it sounds. Then go progressively larger until you reach the size where you like the sound. I ended up with a 1/2" hole in my OEM pipes, don't have those anymore however.

Did you guys do both front and rear baffles?
Thanks,

I didn't, just cut the piggies off about halfway and drilled the rear most baffles. As stated, I ended up drilling them out with a 1/2" long bit. If you also cut the piggies, don't but them all the way back to the muffler. Leave a couple inches so they can be restored later if so desired. Drilling with a 1/2" bit and cut the piggies about half off gave it a nice growl without being obnoxiously loud.

You won't need to re-jet unless you drill the front set of baffles too. Before you do, you might want to search the forum for drone. Here's a couple links regarding drilling and/or gutting the baffles. http://luiscajiga.com/Exhaustm.htmhttp://luiscajiga.com/Exhaustm2.htmAlot of folks have modified their stock exhaust only to regret it later on. Remember, your exhaust is only stock ONCE. If I were you, I'd look at a set of Cobra's or other exhaust options rather than drilling out or gutting your stock exhaust. |

Ditto on what Bruce just said. The PO of my bike cut the piggies and drilled the baffles. I would love to have it back to stock.

I Cut The Tail End Of The Mufflers Off On My Pipes, Melted, ( Because It Is Stainless) ,All Of The Baffles And the "Y" With A Torch. I Welded The End Cap Back On And Cut the Piggies Off Just After The Bolt Hole (Nut) ,That Holds The Rear Exhaust Tip So That I could Put All Three Bolts Back In. Remember To Mark The Exhaust Can So That You Get The Pipe Lined Up So The Tips Fit On In The Right Position. I Did Not Re-Jet The Bike And It Felt Like It Gained A Little HP And It Sounded Great. I Rode That Valkyrie For Ten Years With -Out Any Problems, As A Matter Of Fact I Still Have The Exhaust Because I Swapped Them Out Before Trading The Bike . They Are Hanging In My Garage As I Type And May Use Them Again.
