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.
Is this your first time buying from this brand? Did you consider other brands?
Yes, first Flowmaster......It will not be my last!
Was it easy to install? Any installation tips that will help others?
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.
Any additional comments?
Have a WJ that you want to be able to hear? Buy this now!
