The merge is made by Howe racing. A single borla 4" would be VERY loud.

 

Now that it sounds like I want gonna just put on a single 5" double wall tip. It's a 4" ID so sound should stay the same.

 

Looks awesome! I'm glad this worked out! She runs strong!

 

After putting a few miles on it, I am still very pleased. Cruising down the highway it has zero drone and at highway speed is almost silent in the cab, if I am running next to a barrier you can hear it but in the cab is great. It comes alive fast under throttle but maintains a great sound.

 

That really turned out nice Pat , sounds and looks great , well perfect . Nice job .
