I'm sure you will be as happy as I and others are with the Superstreet. Enjoy.
Removing dB reducer really impacts performance?

So I really like the way the 2;1 S&S looks on a Softail, plus performance improvement . So really stupid ignorant question here: worst case scenario if I dont like the sound, can you put a different slip-on on a full after market exhaust system to solve for sound, or I would have to replace the whole lot?
I should have tried to describe the sound a bit more. The rasp in the exhaust note is not super horrible. For comparison, Vance and Hines pipes are much more raspy to my ears. I haven't heard their 2 into 1 pipes but the big radius and short shots are super raspy by comparison.
The Superstreet has a decently deep and mellow rumble at idle and has a nice hotrod sound when getting on it. As FLS103 describes as "roars like a pissed off lion" when getting on it. I think you will like the sound but you won't know until you hear it for yourself.
Here is a sound clip I made comparing stock pipes to a Bassani 2 into 1 and the Superstreet. Of course the sound on the video clip doesn't quite do the pipes justice but it gives a good idea of the exhaust note.

I was this someone. Not sure how much loss there is to show on paper but it is very noticable while riding. Simply remove your dB reducer and you will see what I mean when I said there is a noticable loss of torque and power down low until about 3500 RPM.
With the dB reducer in, the bike is more responsive down low and pulls harder through the low and mid range. I didn't feel a difference in the upper RPM range with and without the dB reducer installed.
The pipe sounds mean as hell without the dB reducer in but it was too much droning for my ears. Plus I like the way it performs with the dB reducer installed. I cut the dB reducer down to increase the volume a bit. It helped a bit and had no noticable effect on the performance.
Mchad had his on a dyno with the full length dB reducer and a dB reducer he cut down in length as I did and the dyno showed a negligible difference between the two. I'll look for that thread and place a link.

Wish we had one without the dB reducer but again pull it out of your pipe and you will notice the difference. I suspect the dyno chart would look a lot like the one Hulkss posted with a dip down low.

As coopmonte pointed out, there are 2 slip-ons that S&S make for the headers. Not sure if there are any others that would mount up but give them a call and see what they say.

Just to clarify, I have the 50 state legal S&S Superstreet. Three questions:
1. Noticed not even possible to remove dB reducer on street legal slip on, as screws have some security lock on them.
2. Would the sound be very different if I used the S&S Race slip on?
3. can I slip the Race slip on on my 50 state legal s&s exhaust system?
thanks!!!

The stock baffle (open tube, spiral louvers, glass wrapped) on the LongShots made good power overall, but were just too grating on my ears - too loud open throttle, too droning when cruising. I installed the V&H quiet baffles (a capped tube design, shorter spiral baffle) which helped the sound a good bit. This also picked up torque a lot on the bottom, but really crushed the top end. In the end, I bought a set of stock HD pipes, drilled some holes in the baffle cap, and this kept the bottom end and picked up most of the lost top end. Mostly writing this as a warning to those who want skinny pipes with no muffler can - drag pipes look. It's just impossible to get good performance across the rpm range with that design. You can tune straight pipes to make good power, but it usually ends up making good power only at high RPM.

From an earlier post of mine this past month:
I put S&S Slash Cuts on my Heritage and ran the bike for a while with the Decibel Reducers in. Response and torque from idle up to normal shift points is very good. I'm still breaking in the bike so I haven't had the RPM's past 3000 yet. At speeds under 45 mph the sound is ok. At highway speeds I really can't hear the exhaust. I was afraid to pull the DB reducers out because I thought I would loss torque down low.
I pulled the DB reducers out today and found a 1.75 (might be 2 inch) inch louvered core baffle remaining. I then ran the bike and can say the sound is a big improvement from before. I didn't notice any lose of torque either which is a pleasant surprise.
Next step is a Woods WM8-22X cam that I've bought from Fuel Moto along with a Power Vision. I just have to find the time to do the install. I also have the Screamin Eagle Street Tuner which I purchased originally and will download their Stage 2 map once I install the WM8-22X cam. I'll then marry the Power Vision to the bike and make a copy of the original Stage 2 Street Tuner map before I download the Fuel Moto WM8-22X tune to my bike. Sounds complicated but since I already have the Street Tuner I might as well put it to good use so I can always flash back to their tune from the Power Vision before I bring the bike in for service. Maybe...just maybe my bike won't Red Flagged for using the Power Vision. If it does then oh well.
Update:
I've install the Woods WM8-22X cam in my bike a couple of weeks ago and have 510 miles on the bike now with the DB reducers out of the S&S 3.25 Race Slipons. I've noticed no loss of torque down low with the DB Reducers out. The sound has changed and is somewhat louder but still tolerable with this cam. I've noticed more pulsing (jack hammering) of the exhaust note at light throttle under load. At the 501 mile mark in 4th gear on the highway I went full throttle up to 5000 rpm and this setup had the bike up to 100 mph in a flash. The Fuelmoto map is spot on. I really feel no need to dyno the bike.
