to all that are wondering you can install the LNF cat back on a LAP. You will need a flange to bolt up to our stock cat pipe which be obtained at any muffler shop, i was charged 5 dollars for mine. you will also need a piece of 2.5" straight pipe 18" long or a resonator of that lenth if you want to keep the resonator. with those welded on pipe at stock length(either pipe is the same length) it will bolt right up and sound pretty good. I used a striaght pipe and soon will be putting a resonator on to clean up the sound a bit more. i have no vids or sound clips right now.

 

With resonator delete AKA GM fart can
