I recently had a Dynamax(Walker) cat back put on my truck. It was called a Y Toob or something like that. It was very loud. Especially with my hard tonneau. It resonated quite a bit in to the cab. It was way too loud and boomy with the windows up. I went back to the muffler shop and they installed a Super Turbo muffler. Some here said I won't here anything with the Super Turbo. I just want to say that I love the ST muffler. It sounds great when I get on it now and it is not nearly as "boomy". It is also quicker with the ST muffler on. It kinda dogged out with just the "Y Toob" now it is peppier than ever.

Just voicing my opinion on the Dynamax in case someone is considering one.
