Hi i was thinking of putting a Turbo muffler on my XL7 what do you guys recomend and why,would it be better on feul or harder thax.

Hello,

I don't have any info for ya but I would like to hear it if you put one on.  I was also considering the same or trying a dual cat back system.

I have started with a pre-cat back dual Turbo Cherry Bomb exhaust on my 2.7 tracker.  It sounds awesome at 4K.  I do not have the tail pipes on yet though.  Duals were easier than trying to build/install y pipe.

I went from the stock 4-cyl exhaust (the V6's y-pipe outlet mated up perfectly) to 2-1/4", turbo muffler, and low-restriction cat.  Sounds way better, but didn't notice any mileage increase (or decrease) whatsoever, which surprised me.  Power, maybe, but the automatic is so lazy in its shifting that I can't really feel it. 

The biggest performance increase for me at this point would be firming up those upshifts..
