Screamin' Eagle Street Performance Slip-On Mufflers
I've been eyeing these mufflers as possible slip ons. Part # is 80721-09 . How are these in comparison sound wise to either the Thunder Street Performance Muffler Part #65115-10 or the Street Performance Touring Muffler?
I see that the Thunder Street Performance says that they are tuned to worked with the Cat header pipe. I have a 2010 header with the cat removed on the way so...I think mtclassic is running this exhaust with the stock header (cat)
I'm looking for a deeper rumble but not too much louder than stock....the Street Performance exhaust says it gives off a more aggressive tone....is this the wrong slipon to be looking at if I want a deeper rumble than stock?
Hope what I asked makes sense

I have the # 80721-09 on my 09' (no cats) they are slightly louder than stock at idle. Quite a bit deeper tone, they are substantially louder than stock when you gas on it. At 70mph you can hear the stereo without a problem.
They do have the 50 state EPA stamp of approval, which may become an issue soon depending where you live.

I do have the street thunders with cat still in place. I just recently put in baffles from Supertrapp se series (pretty much a straight thru baffle) designed to be used with cats in place and it sounds very nice. Very deep low beefy rumble. I think without the cat it would be pretty loud. The baffle on the street thunder has a little obstruction but still not too much so it would probably sound quite a bit louder without the cat.

Thanks for the info guys...as I said in the other thread I just picked up a set of the SE Street Performance #80742-09 at a really good price. It is the same pipe but black instead of chrome....see how they look with my Sedona Orange 
Yeah I really like the looks of your pipes but thought they might be a little bit louder than I wanted without the cat in place. These pipes say they have removable baffles so maybe I'll be able to change the note if I want to. I'll see how they sound and if I don't like them it will be an easy enough fix to swap them out for something else

Hey Ron- I ended up finding a 2010 header pipe with the cat removed from it. Going to give this combo a try and see how it looks and sounds......I'll probably give the xieds a shot as well

Here's my thinking!
1= Leave the damn thing alone.
2= V&H Dressor dual head pipe with the Jackpot's I have now.
3= Fuelmoto's Headpipe with my Jackpot's.
4= V&H Pro Pipe.
5=Remove the cat from my pipes and see if my jackpot's are too loud/
See how confusing this **** can get..

Yep very confusing! lol Yes that was the guy...I basically sold some floorboards from my VTX and with the same money I bought the headpipe. Yeah it was a little more than I wanted to spend to but considering got all the heatshields etc and someone has done the cutting , gutting and welding it is not too bad. Less than a V&H header plus I don't have to touch my OEM header in case I need it in the future I may get this headpipe cermaic coated as well. Another member here had it done at a place not to far from here and liked the results
Sounds like you have some options lined up.
