Which would you guys suggest for my truck? I see a lot of guys around here with the 40 Series muffler, and I like the way it sounds. I want my truck to sound as mean as it looks. What's the difference between the 40 Series and the 40 Series DELTA? And would you suggest stainless or not?

TIA

 

I think the Delta series is a taimed down version of the regular 40's. As far as the "stainless or not" question, definitely go stainless. However, I don't think Flowmaster offers stainless as an option in any of their lines.

 

Rob, I picked up a 40 delta from Summit, low grade statinless though, 60% off! Muffler only, I was going for sound only. Nice and loud, very throaty. That's my 2 cents! Good luck
