Finally got the BA 7 inch mufflers installed along with helmholtz resonator. Double checked a few items with Keith so went back under the truck to crank down the bolts even harder.
To help make it a little easier I backed the truck up on some simple wooden ramps I made, the extra 4 inches helps out with elbow room.
Since my truck only has 7k miles on it no WD40 was needed, came off pretty easy. You do need to watch when you drop it out that the tailpipe doesn't swing and hit the metal behind tire. I taped up that area just in case but with two people doing it you can catch it.
Brother in law got under with the hole saw to cut opening. The tailpipe has an area after the bend that gets wider and thats where you want to cut. Had to figure out how to drop the spare tire down about 5 inches to get a good angle on the saw. Wish toyota had those rear seats also folding forward, getting the tire tool out was a pain.
I really had to crank down the bolts with the wrench to close the gap between the resonator and tail pipe. Started it up and felt no air coming out-Keith advice.
I can tell there is a deeper sound at start up. Gets really low after it warms up and rpm's drop. Nice burble when accelerating at 2000-3000 rpm's. Dropping it into sport shift to slow down sounds really good, not much pop just a cool muscle car sound. Same goes for accelerating through gears in sport shift, I leave in second going up the long hill just to have that tone. Getting on it sounds a lot better though I wouldn't say crazy blasting. When cruising on level pavement at 45-60 the motor drops to lowest gear, when you go up a slight grade but doesn't down shift its a deeper moan. Its not drone but you do hear the moan. The sweet spot I found so far is cruising at 70-75 mph, the exhaust is perfect.
You can't help but want to blip the throttle at lower speeds just to hear the sound. It's about 75% of what the stock duals on a 70 Goat or Chevelle sounds like. It sounds like a V8 now when you start going from a stop, you don't have to get on it to hear the nice burble.
Some pics below, when I get a chance I will make a Youtube of it at various starting speeds.
