Exhaust help !!!

Good morning all !!! Have a quick question for the experts out here. I have a 2010 L99.
My current setup is speed engineering headers with the connection pipes going to flowmaster American thunder CATBACK exhaust . Sounds great but am looking for a but louder more aggressive setup . Hence I have the BORLA ATAK CATBACK EXHAUST. I was wondering what is the best way to connect the borla atak exhaust to the speed engineering connection pipes that come off the headers . I know there is a difference in the pipe diameter . Borla 2.5 inches v/s flowmaster 3 inches . At some point in a different thread someone had mentioned using the 3 " walker band clamps which worked out amazing for the current flowmaster setup . Just need some info on what size would be ideal for the borla setup . I can't remember the piping diameter on the SE CONNECTION PIPES THAT would.connect to the borla exhaust . Any suggestions would be welcome .
Thanks

if your connection pipes are 2.5" outlet it should bolt-on just fine. i think most catback systems that are 3" will reduce the pipe size to connect with your connection pipes or the stock mid-pipes (2.5")

Take it to an exhaust shop, or call SE and see if that have a different extension pipe with 3" to 2.5" neck down.

The connection is necked down to 2.5" like mentioned above. The Borla catback should directly replace the Flowmaster system.

Unless you got custom pipes from Speed Engineering, your connection pipes are 2.5". The Borla exhaust should bolt right up to it.

I have Texas speed long tubes and the Borla ATAK catback. I just used the factory slip fit that went from the cat to the mid pipe and it worked fine
