I have two super 44's and tru duals from shortie headers all the way back. I like these on this truck because they dont have the constant drone. They get loud only when you are gettimng on it. Now im comparing this to my mustang that has two 40's on it for what its worth. I havnt heard one with the 2 into 1 muffler. but it doesnt drown out the movies or sterio.

 

i had the super44 on my 04 xl and it sounded good and would set off car alarms

 

got it put on yesturday......sounds sweet......didnt notice a gain or loss in power......now its time to kep an eye on the ole gas gage

 

you shouldn't really notice anything but a difference in sound. just means you need to keep yourself from flooring it all the time lol

 

I have the same. like I said before. your doin a cat back system on a truck. Not a street car or lookin for less than 15 seconds.lol Glad you like. I love mine, and added to the C.A.I and the gryphon.. for a truck... is just fine.. ImO.

 

Super 44 isn't so new anymore, came out in March 2007. Too quiet a muffler anyways, get the Flowmaster Super 10 if your stuck on a Flowmaster product.
