Which A/T were you running?Dropped down from 275/55 a/t to a 285/50 highway tread and more year round friendly.

I had Pirreli atrs. The old tread design. I traded my used 420v's and the used Pirreli's for this new set of Cooper HT Plus.

Took it for a shakedown run and to test the exhaust, then to get dinner, then to Walmart.
The mufflers are actually quieter than before, when I had cats, as I thought they should be. I just couldn't figure out how having an extra 22" of muffler wouldn't make much a difference. The noise is what little leaks past the cutout since it doesn't seal up 100%. I stuffed a couple wadded-up rags in it and went for a test drive. It was almost as quiet as stock. I floored it and, as expected, the rags shot out somewhere around 5,000 RPM and the noise was back. I turned around to retrieve the rags and went home, satisfied that all that muffler work actually was a success. I have a plan and parts to move forward in this, but it can wait until cooler weather.
... Besides, I now have something much more pressing to be concerned with:
A couple hours ago, on my way back from Walmart, I turned onto the road that my street is off of. As I accelerated, I heard and a sharp clunk and felt it in the steering wheel. I slowed and looked in the mirror to see if I ran over something, but the road was clear. I let it idle forward and could hear an intermittent clinking. Stopped and revved it in neutral to see if it was the trans- nope. It only does it when rolling. I idled the ~3/8 mile home and parked it. I'll pull the front wheels tomorrow and assess. It's either a blown hub or a broken hub bolt. The hubs have always felt and sounded fine, so I doubt one would just go from fine to this bad with no warning. I think I know what it is since there's nothing else up there to cause these symptoms.

I guess you don’t have a diff up there to worry about. Or CV axles.
