I've been running my jet hot long tubes for some time now with my mufflex y-pipe with a 4" collector and then a reducer down to 3" and then into a dynomax bullet muffler, and a turn down.

the reducer keeps comming loose so i want to do something diff. i'd like to split the exhaust at the end of the y-pipe where its 4". so its almost like an x-pipe, and have 2 dumps.

anyone good at making designs? i want it as loud as possible but still sounding good.

or what about a 4" dump right after my y-pipe???? no muffler. alothough the muffler is straight through it does make a difference.

 

if you don't mind the noise...why not keep it simple with the 4" dump
