2018 Toyota Tundra Exhaust Systems

I got my 2018 Tundra 345ci or (5.7l) V8 with its single standard stock setup which is a 4:2:1. Sounded about as loud as a Prius. So I ordered the TRD dual muffler kit with 2, 27" glasspacks loaded with fiberglass noise canceling packing...always get a 2021 or older if you actually want a V8 plus the beauty of the Tundra is they are true dueled from factory, however, they tie a Y pipe in to make it a single out. The TRD system was barely any different than stock except for a slight more rumble on startup. After 2 years I said screw it and went with a Flowmaster outlaw cat back angled exits out behind rear wheels, for towing in mind. THAT is how a 5.7l V8 Tundra should sound baby! 2.5" on the mid pipes going into a dual in dual out flowmaster super 10 with dual 3" pipes running out. However, I feel they went a little large on the rear pipes. 3" each is a total of 6" piping. So I noticed a little torque loss. However, the sound is 100 percent worth it. What I lost in tourqe I gained in HP. Also running a TRD CAI. I think Flowmaster should redesign the catback kit to follow stock piping a little better. They should have had 2 1/4 on both mid pipes and ran a max of 2 1/2 out the rears however I would have ran 2 1/4 thru and thru. Noticable back pressure loss. With that being said, I am very happy with the Flowmaster super 10 dual in 2.5 dual out 3"! Makes the truck sound like it looks. Aggressive. Not recommended for children or wives as when you get on it, the entire interior rattles and vibrates if you dont feather the pedal. It's a beast at WOT. True Racing Muffler. Much better than ANY other Tundra setup I have heard. Better than Cravens, better than widow makers, equivalent approximately to cherry bomb extreeme. Have not heard powersticks yet so I can't compare.
