    I'm looking at putting a new exhaust on my truck, and right now I have a flowmaster muffler hooked straight up to my y pipe. I was wondering what everyone suggests I should do. I was thinking about a single-in/dual-out muffler setup, but I will still have to find myself a cat.

    Any ideas would be helpful!

    I went with a single 3" aluminized exhaust pipe from the Y back. I also have a high flow 3" straight through cat converter and a flowmaster muffler. Keep in mind with dual exhaust... when you lift/change your rear suspension setup, those pipes are norrmally in the way. The fewer the pipes the better down the road. [​IMG]

    Surprisingly dumps aren't that bad on a blazer. I have dual pipes run back to a set of 40 series deltaflow Flowmasters and dumped right in front of the axle. It sounds great, quite a bit of interior resonance though, makes all the loose screws rattle in the truck. If you don't mind noise then I suggest dumps, I don't have any problems with fumes with the top on or off. The only thing that I have to deal with is the dust that the pipes stir up on dirt roads at idle.

    Just my .2

    I just finished my exhaust tonight /forums/images/graemlins/grin.gif I have Thorley Tri-Y headers, Dual 3" pipe, 2 Flowmaster 50's...Right now the 50's have no tail pipes on them..But I am going ot add tailpipes or just dump it in front of the axle...

    IMHO, it is a little too loud...I am going to switch the mufflers I think to Dynomax Ultra Flo rounds or Magnaflow...
