Yeah, my magnaflow is a little quiet but that's what I was wanting. It's the biggest one available. With no cats it is plenty loud, I would like to get a smaller one though.

You can run true duals. I had true duals before I put my LT's on. I switched to a single 3" because a single 3" will outflow dual 2.5's.Originally Posted by lowchevytrucks8503

I've got true duals, muffler has a built in X.
I thought that the 3" single gave it more back pressure for lower end torque. Not saying that true duals is better, it just doesn't make sense to me that a 3" pipe has better flow.

I have dual 3 in 3 out Magnaflows, no cats, and all car alarms jump when I pass by at 1500 rpm.....I bought them cause everyone says they where almost stock sound at idle.....even with the turbo muflering the sound is like storm coming.....I luv it, but sometimes I wish it make less noise.
If I was a musician, I'll say they have too much bass
that sounds like a good idea actually...they look like cats a lil bit...might help on my inspection
I've never had anyone crawl under my truck for inspection
