Hey guys. I am getting a Flowmaster off eBay this afternoon. Can someone tell me the difference between the original series 40 and the Delta Flow 40? Which do you guys recommend between the two? Also which model number do I need to fit in my 02 runner if I keep the pipe and everything else stock, just change out the muffler. Thanks again guys.

 

original series 40 has one baffle and the Delta Flow 40 has three bafles more info at http://www.flowmastermufflers.com/mufflers.html

 

bump, guy's please help. Thanks.

 

i dont know alot about 4runners but do a search that will help

 

are you serious?!



the regular 40 is louder... the delta isnt as loud

 

I wasn't really as concerned with the loudness factor as I was in what size do I need for my runner. Does anyone recommend the 50 series over the 40 since it's a v6.

 

if u want it a little quieter go with the 50 and the stock exhaust is 2.25

 

Thanks Elton, I really appreciate your help.
