I'm new here and I'm just looking at inexpensive options to make my 06' 2500HD 6.0L Crew Cab/ Short Bed 4x4 a better running machine. I heard Flo Pro HD mufflers are a good way to help my engine flow better. The stock pipes are very good imo and I don't think a whole new catback system would be better than just replacing the muffler and maybe cats in future.

Now! According the FloPro's site there are no dealers in Texas and I can't find crap on ebay. So where can I purchase them online? I'm interested in 2505 or 2506. Not sure how much noise I want yet lol.

 

From Google:
Flo~Pro Although after looking, I don't see the ones you wanted. I have the 2504.

I'm sure there are many other places. I agree with you about not needing an entire catback.

 

Today's your lucky day! I've got a FloPro 2503 dual inlet and single outlet with a mandrel bent 3" tailpipe with a Corsa dual outlet stainless tip for sale. This could be yours for a penance. PM me.
