What's everyone thoughts on Cobra Slip-on's 4"I can get a set for 200.00 installed

That's a pretty big baffle. Statistically there is often a "dip" in the lower end torque with monsters like that, but if performance isn't your number 1 priority, you may be fine with it. I cannot say however I have personally ridden a bike with them.

I just purchased a 2016 ultra  limited low and had a set of the 4.5 race pro installed with factory head pipe and big sucker stage 1..I am not chasing hp or tq..I like the looks of them they sound real nice to my old ears and you still can hear the music at 75mph with no trouble..and have noticed no change in hp or tq which I shouldn't unless I dump the cat from what I have read anyways please correct me if I am wrong

And for $200 that's a steal I paid $689.00

I bought the Cobra 909 Twins 4" Slip on's to go on my 110 cu in Screaming Eagle. They have a sweet low rumble and quiet down on the cruise. When you lean on them they will make some noise. I seem to have a little better performance over the stock CVO factory mufflers, but that is by the seat of my pants feel, so it might be BS. I already have a V&H X-pipe on the bike, so I hope the 909's are going to be compatible. I wonder what the performance cost / benefits might be. Ill probably never have this bike on a dyno. I know this is a little known brand of mufflers, at least to me. There seems to be 3 major players, and Cobra isn't one of them. I added a link to them so if anyone wanted to check them out and give me the low down.   I am looking forward to your feed back.

I definitely like the sound and looks of them. Sorry, didn't mean to imply you would automatically suffer this dramatic power loss. My experience with the Vance & Hines High Outputs (also a large baffle) was a noticeable hit on the low end. Seemed to not want to wake up until about 3000rpm.
