would increasing the diameter of the exhaust pipe from the cat back increase the sound of the exhaust???

 

you bet it would mos def make it alot louder and it also depends on what knid of muffley your using and the size of the exhaust

 

I agree to that answer. In addition, there is a muffler called the cherry bomb II it sounds great and is
perfectly legal.. It will give you the header sound but not quite glass packs.. Its about 45.00 dollars but well worth it at some auto parts
store..
