Ok i just bought a muffler....not the shi#@y one off eBay a different one for now just to make some noise till i can afford some nice header back. I was wondering the new muffler is 16.75 inches and my muffler is around like 26 from start to tip so i'll but some exhaust pipe about like 27 in and cut it down my dads a pro fabricator so it will be no problem welding it im just wondering what size pipeing does an 02 EX have is it 2.5 in and is it i think ido or odo or somthing im not to good with this kind of stuff i just want to know what size diameter should i buy? Thanx.

 

the stock pipeing is not 2.5 by far. its more like 1.25. the most ideal aftermarket/mod pipeing wil be more on the lines of 2.25
