I'm installing a Rips 4" system this morning and need to know which way to put the muffler on? It doesn't have an inlet or outlet marked. The differences are when you look inside is that one way all the little "scoops" will be used or if I flip it around the other way, the "scoops" will get passed over.
I don't want drone....so which way should I put it? My gut is telling me to use the scoops...
Please let me know what you know......I'm right in the middle of the install!
Thanks

 

No idea here Why don't u email him? Here is his address. rip@protintnw.com

 

Got it figured out.......Rip called me...my gut feeling was right!

 

well, how does it sound?

 

Sounds pretty good....not quite as loud as I had thought tho....but it keeps the neighbors happy!
