I have a question, does it have the flange for a 3" catback or does it fit the stock 2.5" catback? I saw no option on the site to change the flange and want one for a 3" catback(plan on ordering both at the same time)...

 

On the LNF, the stock catback is close to 3" at the entrance and tapers down to the resonator. Because of this, our 3" downpipe exits at 3" so it can be used on the stock catback or a 3" catback. With a stock catback, there will be about a 1/16" lip around the entrance compared to the exit of the downpipe, but when running a 3" catback, it will match up perfectly.

 

sounds good
