Did you notice a difference from the S&B?

It should be 2.75”, if going weld on tips you just go 3” as there are more options.

You can get the 6.2 with factory dual bumper exit with the screen in 2020. Like my LT trail boss. To answer the your question, look for and offset in center out or offset / offset. 3”.

No down side, the flapper should be removed when changing the muffler. The muffler is big, heavy and restrictive . You wont get an aggressive tone with the screens in place , if you have the resonator screens if not and you have an actual resonator then the same thing, it should be removed unless you are after a milder tone. All these components are after any sensors so no issues with codes or anything. Ill post some pictures of how she looks.

Yeah, I can only speak to my truck. With the duals rear exit . I know some trucks have side exits. But these trucks are well sound insulated. Quiet in the cab. https://www.blackwidowexhaust.com/mufflers/Race-Venom-3-offset-offset-SKU-BWOOR-33-p108144418

Quick cold start and a few revs . didnt want to rev her to hard its late lol. https://streamable.com/5jr012 https://streamable.com/qvr525

Dropped my truck off this morning to get the resonator screens removed. Cutting the section out containing the three screens on each side, welding in 3” pipe . Its roughly a 12” section on each side. Flapper was removed with stock muffler and a black widow put in place. Just picked it up. It sounds way better with those screens removed , and I also feel like the truck has more bottom end with screens removed . Driving at 40km/h , 60km/h and 80km/h. No drone whatsoever. Its shockingly silent in the cab at cruising speeds. starting thread to upload some videos after work.

Emissions legal? Must be talking Cali. Anyway just thought it should be brought up you can buy just the muffler from borla and still get no drone and effectively accomplish the same thing. A cat back exhaust system on these trucks wont produce much if any more than a muffler swap/ flapper delete.

Curious On this . These “Catback” exhaust systems are just that, from the cat back replaced. why pay all that money to replace GMs OEM piping which is already stainless! The only gains you Get are from the muffler swap , taking the old muffler out with the flappers and replacing with a high flow muffler no flappers. essentially that 13 HP gain for $2000 dollars can be had for around 200-300 dollars. save your money people, replace the muffler you will get the same gains and sound or better lol. as far as a cold air intake , get S&B , Volant or Cold Air Inductions. They make much better design intakes and filters. Disconnect the negative battery terminal during installation. This resets the ECM so it can re learn the fuel trims . No need to get GMs “Tune” . Its not a tune.
