I really like my Cobra Black Slashdowns but I did notice a bit of sluggishness with the SD baffles that wasn't there before. Sound is great but just a little too loud.
I put in a set of Cobra Quiet Core Baffles and it really made a difference. The Super Loud Sound is still good and loud, but not as harsh. And my stock 103 engine is liking the back pressure.
No more sluggishness, very minimal popping at slow speed decel. Plan to put a Cobra FI2000 on soon anyway.
Highway speeds are noticeably quiter, just low, loud rumble, and gets plenty loud with throttle twist to warn the cagers.
I'm very happy with these pipes now.

Those look great with the black bike.

 

did the pipes come with the baffles or did u have to order those seperate?

 

only reason i ask is because i just ordered a set of cobra speedster short swepts for mine today and it says they come with removeable baffles and im hoping they are the same as what you are talking about
