No, many people feel these cars don't sound very good with most exhaust systems and I tend to agree. I just have the DPs and I'm happy with it. Maybe I'll delete the 3rd cat at some point.
So this morning I took my SHO to my buddies shop for its annual NYS inspection. I hadn't been there since early June when the mechanic (Dan) and I installed my PPE downpipes. I see Dan and he immediately says he has some pics on his phone to show me, he starts scrolling through pics of Andrew's...
I had something very similar, a distinct ticking sound when turning the wheels when barely moving or even sitting still. I noticed it most when pulling in and out of the garage. Turned out to be the driver's side wheel bearing/hub assembly for me. Only about 35k miles on the car at the time.
These are what I have on my car, very happy with them. With the flower wheels I had to shorten the unthreaded part of the factory studs for clearance, but that wasn't a big deal.
