any of you out there who went with the flowmaster 50 series muffler with 2.5inch piping, could you tell me what the part number is for that muffler and how much it cost you? thanks

 

call a local muffler shop and ask for a 2.5" flowmaster series 50. at goofy's (a shop in town) it costs around 75-90

 

I called my shop and they told me flowmaster doesn't make a 2.5 center in/center out in stainless, and for the aluminized one they want 120 bucks not including shipping...they reccomended a MAC muffler but i hear they aren't very good sounding. anyone have any experience with MAC mufflers? their one made out of SS is only 80 bucks.

 

last time I checked, ebay had some good deals on flowmasters. just a thought.

 

all i have to say is: magnaflo :drools:

 

Y U want one?

 

I'm using a Flowmaster 50 series SUV (larger than the 50 series)
2.5" offset inlet, 2.5" center outlet part No. 52556. This is the biggest low restriction muffler that will fit a Max; ans that's what it took to reduce sound to tolerable levels (still nowhere near 'quiet') when using a Warpspeed Y-pipe and mandrel bent B pipe. Installed it was $161 including local sales tax. Here's a link that shows the same model
