Review of my V6 exhaust setup: BBK shorties and x-pipe, Force II

When I was selecting my exhaust combo I couldn't find reviews of the combo I wanted so I thought I'd give a review of what I have. My car is a daily driver so I wanted something that wasn't too obnoxious so I selected BBK shorties, BBK x-pipe and Flowmaster Force II axle back.

I installed the x-pipe and axle back at the same time so I can't comment on just the mufflers (wish I had done one at a time for comparison purposes). I was extremely pleased with the sound at start-up and idle. Sounded V8ish. However, the sound got very raspy at higher RPMs. I'm not sure if the raspiness was a result of the V6, x-pipe or the mufflers since I installed both at the same time. The raspiness was so bad that I would have eventually tried the stock h-pipe, except I still had to install my headers.

After the shorty headers were installed things improved greatly. There is still a bit of raspiness at higher RPMs (again, could be the V6, x-pipe or mufflers) but I don't feel the need to change anything. The sound got much deeper and aggressive but not so loud at cruise that it bugs me.

After going back and listening to a bunch of exhaust clips I think the Force IIs are some of the least aggresive axle backs available. Comparing my car to the clips I can pick up on sound nuances that I didn't catch before. If you're looking for the absolute deepest sound available then you'll probably be disappointed with the Force II, but nonetheless they are still an improvement over stock.
