7.3 performace upgrade questions???
 

Hey everyone ,

I am new to this forum and to the Power stroke family.
my first question was which cold air intake do you guys suggest for the 7.3??
My second question is in regards to my exhaust system, i have 4" pipe with a magnaflow muffler. would it sound stronger and have better performance if i remove the muffler??

The muffler question is all personal taste. I prefer a muffled powerstroke but many others prefer a straight pipe.

As far as intakes go, search the internet for "tymar" or "6637" in conjunction with "powerstroke". By far, about the best filtration and flow you'll get.
