What is the difference between the SE 50 state legal 80495-07 and the 49 State legal 80378-00 Slip Ons?

When I first purchased my 09 Heritage in Sept. I had SE slip ons installed and after a while thought they were to quiet. I went with Rush and now I don't like the metallic sound.

Soooo.... Today I went and purchased new SE slip ons again (sold the other ones) and I swear these are louder and deeper than the first set I had. This set (80495-07) that I installed today sound awesome, just right for me.

I am not sure what the model # was on the first set as I am still looking for the receipt so thus my question what is the difference between the two.

Thanks

can't "sell/use" the 49-state one in California...I suspected this would sound better (since it would be less restrictive and would flow better)

 

Here is a short clip of the new ones, they are much louder and deeper than than last set.

 

nice idle. bet that baby sings when you open it up

 

Here is a photo of the pipes after install today, I will redue video tomorrow in the daylight and make it longer.

 

Just a thought not to derail your original question: Rush offers different baffle sizes. Perhaps if you went with a different baffle, it might take away some of the metallic sound that you're not so crazy about.

 

Ooops....didnt see you already went with the new S/E's. I watched the vids and they sound sweet...guess you can can the Rush baffle idea ;-)

 

Anyone else have an idea what the difference is in the two pipes, what do they do different in the manufacturing process to make them different?

 

The 50 state should be a catalytic converter type
