out with the old in with the new! it sounds so much better now even the exhaust shop was like WHAT THATS A LEXUS? no drone at cruising speeds what so ever. at lower speeds like 20-35mph you might hear some drone but its just noticeable. the cars pretty well insulated. sounds great at WOT. I do wish it was a bit louder but I really cant complain, compared to stock this is just perfect and for a luxury car its just the right amount. I'll do a video once the mufflers are broken in, don't even know if that's a real thing or not.

I have to agree that it is a more efficient system than factory. Are those pipes touching the heat shield?

Wanted to add that this is what the 460 guys are doing with J-pipes or a Heimholz chamber. Post #59 has the J-pipe length to adjust the frequency of drone.

The main problem with all this is someday the epa is going to crack down on these mods, and pretty much ruin the car hobby for all of us. As far as I know your not suppose to modify from factory stock any of the emission related stuff.
