Had a shop install the 94106 on my truck yesterday, and man did it make a difference. More aggressive growl and definitely louder. I still dont have that much sound in the cab which is great and on the interstate it is quiet unless I get down on it to pass someone

I tried to make a video to post but the sound quality on the camera was awful

 

cool man. Explain your system setup.

 

just a simple SI/DO flowmaster 40 w/ 3.5x18 ss tips. At first I wanted something with just a little rumble, and well I was wrong...So I got the 94016 high flows!!! May eventually want the 11" magnaflow or the super 44 havent really decided but what I have now is pretty good for now.

 

Super 44 wont be all that much different than the 40 series. If you are ever going to change mufflers for a better sound thats also louder, Dynomax Bullet or Magnaflow Magnapack with a Y pipe to mate you tails to.

 

x2 Hi flows are always a nice addition

 

yeah the high flows made my super44 sound great

 

Did you replace all four or just the last two?

 

Darren,
I dont necessarily want something alot louder then what i have now ,but in future i may want something that sounds deeper. My orginial setup without the high flow cats was ok but not as loud as I wanted. Alot of the guys on here are pro flowmaster or pro magnaflow, and they are definitely different but I like them both. So i may go magnaflow in about 20,000 miles

Meangene,
My truck is an 08 so i only have 2 cats.

 

High flow cats are one of the best mods I have done to my truck.

 

Well if you want a deep tone, Magnaflow & Borla is your winner. The Borla Pro-XS will be what you want. 14" Magnaflow would be good too but the Borla sounds better at all RPMs. So when you want a muffler switch and the same volume as now but deeper, remember Borla Pro-XS.

 

Your flowmasters will be rust cans in 20k!

 

^thats what i was counting on
