Anyone used the Flowmaster 70 series muffler?

Kind of curious about this muffler. Looks similar in size to stock. I would like to find something that would free up the flow, keep the interior noise to a minimum and be a "little" louder than stock. Think this one would work?

Seems like a popular muffler is the 50 series SUV muffler. I've been to a couple of local muffler shops looking around and found that it is hard to make the 3.7 6 cyl have a good deep sound. I don't want the revy Japanese vehicle sound. I'd rather keep it stock than have it sound that way! Interesting, one of the muffler shops that was familiar with the 3.7 said that the stock muffler was sooo HUGE to allow an expansion chamber to deepen the tone. I have to admit that the stock muffler does give a pretty good deep tone, but just not loud enough. So, that was my thought on the bigger 70 series muffler!

That sounds similar to 50 SUV series.

Yes it does, but it is about another 5 inches longer than the 50 SUV series. Just trying to find a good way to go!

I haven't done much research on that particular muffler, but if the LENGTH is the only different dimension, then I can only assume that means you're removing more tailpipe to get the muffler welded in there. Any semi-competent muffler shop should be able to help you with any issue that may come up with a different muffler. Just be sure that inlet/outlet diameter and placement will fit to you existing exhaust pipe.
Just my 2 pennies though

If its longer than the 50series then that means youre not adding as much pipe. If the 70series is 5in longer then it should be almost the same length as the stock muffler.

I got the MagnaFlo it has a deep throaty sound and didn't cost near as much as the Flomaster. Not bad mouthing the Flowmaster it was almost double the price. So I'm cheap!!

I paid $150.00 at shop in Lakewood Colorado that price included instalation it was too good a deal to pass up not to mention it sound really sweet. But to be honest i have noticed no increase in milage or performance but is sounds really good .
