I have a '98 SC 4.6 Triton and I'm interested in upgrading my stock muffler with something that will provide me with a good agressive sound as well as make sure I don't loose any low end torque since I have a TT to pull. From what I have read so far, it sounds like the Magnaflow gets a strong vote in this category, but I really like the sound of the Flowmasters. In doing some research, Flowmaster has the 70 series that claims to be perfect for tow vehicles. Anyone have any the 70 series installed and can provide a testimonial? Any other options I am missing here for this type of application?

BTW, my plan is to replace the muffler only and keep the stock pipes. Christmas is coming, so budget is an issue.

 

thats a prettyh good muffler but it wont sound all that aggressive. It will just sound good & quiet when you give it throttle. 50 series would be better,

 

i agree, the 50 series would be better. normally i reccomend the 40 series or super44, but they are extremely loud and annoying when towing uphill. the 50 series will be just perfect for ya
