lookin for an aftermarked cat, what size should i get?

stock can have 2.25", 2.5", 2.75". If you have headers, 3" is normal. If you don't have headers and need a new cat, now is a good time to get both.

yea i was planning on having a 3" all around.....does it matter how long the cat is? cause i see 16 and 18 inch ones...how long was stock?

Are you looking for an OEM replacement or a hi-flo cat? My Hi-Flo is a lttlie less than half the length of the original 20 pounder I used 3in as well. Gave the exhaust a nice raspy tone that sounds great out my cut-out.

im getting a hi-flow cat...probably a catco

20 pounds holy sh*t!

Summit carries Catco OEM replacement cats, I got my dual cats from em.
