I've been looking around all morning, but haven't had much luck finding anything. I've listened to several magnaflow sound clips, and searched around on the muffler specs. I was wanting to go 2.5" on my 2.8, but all I could find was 2.25" for the inlet. Is that my only option, or is there something I've missed? If there isn't a 2.5" then I'll just go with the 2.25". Any insight would be helpful
