I plan on keeping my Denali quiet.... Well, stock quiet for a 6.2.

If I want loud I also own 2 mustangs. The loudest one is my 95 5.0 that has a built heads/cam/intake motor with Vortec supercharger and meth injection. 600hp through longtube headers, off road (cat-less) X pipe, and MAC mufflers and tailpipes, all 2.5". Yes it has a 2000 rpm drone inside, but the wine/whistle of the blower makes ya forget about it.... Lol

Man, that sounds like Lieutenant Bullitt's Mustang! Sweet!

Ok, so give us run down of what you did from the heads to the tailpipe again to recap.

JBA shorty (cat4ward) headers with titanium ceramic coating.

Custom 2.25" Catless Y-pipe which comes back about 1.5' - 2' further than stock before it Ys together.
rps20190312_212539_504.jpg This is where the factory Y came together just in front of the transmission crossmember by the transmission pan.

rps20190312_212557_127.jpg and this is where it comes together now about 2' further back just before the next crossmember.

Yes, not a lot of snow here, but 60-70 mph winds. Apparently it’s a “Bomb Cyclone” now.

Got it inspected by the dealership today. As soon as I left, maybe 5 miles, the check engine light for the s2d2 o2 sensor came back on, lol. I went through my radio, cleared it as I've done 40,000 times and kept it moving down the highway. I'll get that bung fixed one day.

I had 20% tint applied to my front windows today to match the factory tint on the rear windows. I like the look a lot better with full tint. I would love to go darker, but I don't want any unnecessary attention.



I then came home and removed the center speaker on the dash so I could fix the excessive bouncing, as the retaining clip on the small dash separated from the large part of the dash. I just used some foam to brace the two dash pieces and eliminate the bouncing. I previously had a business card jammed in there to separate the parts, as the bounce created noise similar to fingernails on a chalk board.

I also added some more foam to support the center speaker so it wouldn't crack my dash (like I read from @Doubeleive did), as I felt like I was one of the lucky ones....

I ended up cracking the dash. Right by the upper left corner of the airbag. Like everyone else. I guess I'm part of the club now.
