Go to the Magnaflow site...you should be able to find the part number there.

 

I got my 22in. Magnaflow POLISHED magnaflow Si/So, 3 in. piping (bent and welded by muffler shop), 2.5 to 4" RBP adapter, and 5" Dia. 12" long RBP tip, all for about $320...

RBP stuff from autoanything-about $150
Muffler from Summit - about $110
Bend 3" piping, and weld everything from local shop - $80

 

Been there, done that. No part number off this kit 16518.

 

Performance peddler on ebay, $380 shipped! Putting it on tonight!!

 

NOt sure if you ever got the part number but it is 12256.

there is a guy on this forum or 150forum that is selling his $50.. he got it for $80 on performance peddler but doesnt like it.

 

I wanted a single in and single out side exit so I bought the canister for 60.00 shipped and then paid a shop 40.00 to weld it in, had it for 7 years with 0 issues, so total with chrome tip was 106.00.
