has anyone tried the flowmaster exhaust on the xfire? i have been checking out the forum all morning and have only heard about the magnaflow. when i did the exhaust on my 2001 tundra we tried the magnaflow first and then the flowmaster. the flowmaster makes my truck roar like the good old fashioned american muscle cars. nobody can believe that it is just a stock tundra 4.7L under the hood. much deeper and louder than the magnaflow. im going to experiment with both unless there is a reason that the flowmaster wont work on the xfire. any comments?

oh ya, FYI: a very good mechanic i know claims that they experimented with different exhausts looking for the elusive extra hp and mileage its supposed to create. the only thing that made any difference at all was the header back true dual with the straight through glass packs. according to him it wasnt much of an increase either. my cat back flowmaster w/single into dual exhaust (fake) may sound a lot faster but it hasnt changed by even 1%. only one muffler place out of six would confirm that the hp gain was a myth.
