2004 Tundra Access Cab
These are great headers. Install is a B***h though. Passenger side can be done with a socket wobble extension set, some swivel heads, and crowfoot sockets. Take the wheel off and get into it. Lock Tight and torque em down. Driver side is a lot harder. The motor mount really is in the way. I did passenger side 100% torqued to spec and had a shop hook it up (tow it there!) with the driver side only $300. Somebody with more experience than me can do it. Immediate throttle response and deep sounding
Flowmaster American Thunder 2017 Tundra 5.7
I bought the American Thunder system it sounded great outside but the drone at 1600-1700 rpm in the cab was to bad for me,I swapped out the original 40 series muffler that came with the kit with a super 40 delta flow series and it sounds 100 times better just as loud outside the cab with a much deeper tone and no interior drone what so ever, I got such a good deal on the kit I didn't mind buying the super 40. Would buy again.
