I was looking at putting duals on my 4.6l f150 supercab 4x4 and was looking at flowmaster but over $300 for a exhaust isnt in my range. I was wondering if anybody has the summit dual exhaust. Cuz i was looking at it in the book and its only $150 and was wondering if anybody has any input on this system. Also i was wondering if you could just buy the flowmaster muffler for $50 and replace the summit muffler with a flowmaster. OR if anybody knows any other good cheaper exhaust kits thanks

 

my .02 is buy the summit duals, and look on ebay for a flowmaster. my 5.4 came with duals when i got it and all i did was search ebay and got a flowmaster 40 series to replace what ever muf the guy had on there. the flowmaster came to under 60 shipped brand new so you can find decent deals.

 

get a flowmaster dual in dual out and go to a muffler shop have em fab u up something. but if u want be sound get a true dual u get better performance out of it.
