Cobra Replacement Quiet Core 8 5/8 inches - Speedster Shorts, Speedster Slashdowns (ex. M109R)

Don't replace reverse

I Took the cobra slashdown street rod baffles out to measure the lenght. My DB level would not pass SI it was 7 db too high. I was going to order these but I found another site that had these same baffles and stated the specs. for noice reduction was 3-5 db. I found an article were appearently another bike had similar problems and simply reverse the baffles that were in the slashdowns. I check it out and discovered doing so would restrict and exhaust flow a little more, so I too reversed the baffles I can't believe how much quieter my bike sounds and still has a better deep rumble, also I notice what appears to me as a little more bottom end torque. No more slight backfire when backing off quickly.
