2500 Hd Muffler With Si/so - 2007 Classic

[davzog]

I have about 1500 miles on my Classic 2007 Silverado HD 2500....I think it about time to wake up the exhaust. I want something quiet for towing but with some rumble. After a lot of searching, I had opted for the FLO PRO DI/DO direct replacement muffler and was about to order one.

 

Then I actually looked under the truck, expecting to see a dual-in/dual out muffler going into a single tailpipe.

 

Wow...it a has a single inlet and single outlet, bot appear to be 3 1/2 inches in diameter. I was surprised...is this because it is a 2007, even though it is the old body style? Do the NBS trucks have a single exhaust? I dunno!!

 

So, now I am searching all over again...what to do????

 

I did find that Flowmaster has a 3.5 inlet and 3.5 outlet offset 50 series big block muffler....I am just wondering how loud that would be.

 

Anyone know of any other options??? Thanks in advance....

I have a 2006 GMC CC SB 5.3 and I have the 50 seris Flowmasters.... and I could not be happier.... nice sound at accelerationa and little rumble at idle at freeway speeds there is noooo drone at all.... I would recommend that. I think I put a vid of the exhaust on here somewhere.....
