The best solution to this in order to keep performance and sound qualities is to replace your current exhaust.
tho the screamin eagle exhaust systems allow more flow, they are not up to a racing par along with vance and hines or thunder header or so on
screamin eagle is kept in guidelines under the epa so sound is on the lesser side and so is performance,
i would check out thunderheader.net
their systems are the best performing and sound 100% amazing
i will warn you that they are not the prettiest things out their tho
other than that there is on some model screamin eagle exhausts is a small allen button head screw that will remove the baffles. and some don't

How to remove baffles
The best way to learn how to do this is to go to youtube and watch a video on how to do it. That's the way I get the answers to all my stuff I have the same bike and have done all my work. Once you remove the baffles you will need to put tourque cones in the exhaust between the pipes and the cylinder head to provide enough back pressure so your engine will run right. The Harley shop has them they don't cost much. Just a doughnut shape piece of metal. Then the bike will run good and sound good too.

My suzuki gsxr 1000 k3 will start then cut out six times before it runs properly on its own in the cold
Instructions
  1. Take Down
    • 1 Park the motorcycle on the kickstand or center stand and allow the exhaust pipes to cool completely.
    • 2 Refer to your Suzuki service manual and organize the metric tools needed to remove the baffle. On newer models, it may be necessary to remove the tailpipe section to modify the baffle. On older models, you may be directed to remove a bolt that secures the baffle in the tailpipe.
    • Follow the procedure given in the manual and remove the tailpipe section or slide-in baffle using the appropriate tools. Save any brackets or bolts. Place the tailpipe or baffle on a workbench.
    Tailpipe Baffles
    • 4 Hold one end the tailpipe up to a light and look inside the other end. Depending on the baffle, you may see very little light or none at all. Modifying the baffle is a matter of opening up areas in the baffle.
    • 5 Chuck a 1/4-inch drill bit in an electric drill. Use a bit extension if necessary to reach deep into the tailpipe with the drill bit.
    • 6 Place the tailpipe on a workbench. Use a towel or rags to prevent scratching the finish. Insert the tip of the drill bit into the tailpipe and drill a 1/4-inch hole in the baffle.
    • 7 Hold the tailpipe up to the light again. Determine the number of additional holes you want based on the purpose of the modification. Drill additional holes in the baffle if needed.
    • 8 Stand the tailpipe on end and tap it on the workbench to clear the debris from drilling out of the baffle. Make sure all debris is cleared out before reinstalling the tailpipe on the motorcycle.
    Slide-In Baffles
    • 9 Secure the outer end of the baffle in a bench vise with the baffle extending to one side. The outer end has the threaded hole where the bolt was removed to take the baffle out of the exhaust pipe.
    • 10 Measure the length of the baffle and divide it by four. You modify a slide-in baffle by cutting off a one-quarter section at a time using a hacksaw. Mark the baffle at the one-quarter point and cut the first section off the end.
    • 11 Reinstall the baffle in the exhaust pipe using the saved bolt and the metric tool.
      Start the motorcycle and determine if the modification produced the desired result.
    • 12 Allow the exhaust pipe to cool completely before removing the baffle for further modification. Most likely, cutting one or two quarter sections will give you the result you want. Avoid cutting too much off the baffle, or it will be useless.

Have 07 xl1200c sportster how can i make exhaust louder have standard pipes on dont want it to loud just more of a deep thud money tight dont want to keep with original pipes for now
Screamin Eagle mufflers work well. I've been running a set on a Dyna Wide Glide for years. They're not as loud as straight pipes. They come with removable baffles, I think. It's been years since I've mess with them but they used to. Also, some pipe manufacturers made "slip on" muffler replacements. They're much better for performance too as they present the engine with a bit of backpressure that the drag pipes do not.

Good luck

BACKFIRING 2000 DYNA AND ENGINE LIGHT AFTER 15 MINUTES
Running too lean, if you changed the mufflers to screamin eagles without re-jetting you will get this problem.
