hey guys i was looking at thrush mufflers at summit. i know a lot of guys run them so i want to know which one. there are 100 ?s that summits site asks. i dont know anything about the size i need. my jeep is an 89 renix. i was going to go with another brand but for the price of the trush you cant beat it. im just going to put it on my stock pipe so all i need is the muffler.
