Now that I got your attention I have a question.

I just had a set of 2" Rush exhaust put on my 07 Ultra that has had a Sert and Stage1 installed.
I may be too loud and deep for my satisfaction. The bike was just Dyno'd yesterday. Can I go back to my stack exhaust
without causing any problems or having or re-dyno the bike? I thought as long as I keep 2" or under I am OK is that right?

Thanks in advance.

 

Did you consider installing a 1.5" baffle? I just installed the Rush 1.5" and nothing else and think the sound is great.
No deep throat here . . . .unfortunately.

 

Yes But,

I had a buddy that had 2" Rush on his new 08 Ulltra. He decided to do some major rebeuilding and used something else.

I bought these for 200.00. I think it issounds too loud for me when I am riding 2 up with the wife. I will try it tomorrow if the weather holds for a few hours.

I thought I could just change back to the stock mufflers. I don't want to have another dyno if possible. But of course I don't want to screw up my bike either.

 

I would say on the one hand that you'd be okay to make the swap-back. But the flow characteristics are some different and it won't be as good as it is now.

When I put my 2" Rush mufflers on I initially thought they were going to be too loud too. But I've since gotten over that fear. They're perfect.

 

On my 07 SG I did the stage1,air cleaner, 2' rush and at first i thought it was a little loud, I thought well I will try them for a few days, well that has been 6 months ago and I still like them.

 

You can change the baffles out for 40 bucks. Just have your dealer order you a set of the 1.5 and install them in about 5 minutes.
