What made you choose this particular product?

Hours of listening to videos and reading online reviews trying to find a muffler that sounds good, but doesn't drone.

Yes, first Flowmaster......It will not be my last!

I had it welded in with the rest of the system by my favorite local exhaust shop.

Once you've had a chance to use the product, did it meet your expectations?

Sounded awesome for the week I had it on the stock system, no drone at any speed. It has a nice throaty note, it's exactly what I was looking for.
