I just got a MEGAN Racing 4" exhaust muffler for my 90 CRX and was wondering 2 things. What is the stock diameter of the exhaust pipe from the cat on back to the muffler? Also where is the best place to get 3" piping for my CRX on the internet for a reasonable price. Thank You.

 

the stock pipe is aprox 1 3/4. and if u were lookin for 3 inch pipe i would go here http://www.foxraceco.com/index.php?m...ath=89_8_21_23 i was thinking about getting my pipe from here. all u need is a muffler or resinator....well thats optional
