What the heck, I have some time before the Super Bowl.
I went ahead and did the "golf tee" mod.
Started it up. No CEL light or anything. It does "seem" to have a bit more growl but only when standing next to the exhaust. Couldn't tell the difference while sitting in the driver's seat.
Didn't get a chance to drive around because of this…
It's been in there since Sat. around noon (PST). A new tire will be in on Monday. BTW, if anyone gets new tires MAKE SURE YOU PAY FOR THE ROAD HAZZARD WARRANTY. I was dumb enough to not get it and instead of paying an additional $20 per tire when I had them mounted, I'm paying $200 for a new tire. I've only had the tires for two weeks. This would have been covered under the warranty. Dumb, just plain dumb on my part...
