My first dual exhaust set up:
O/R H-Pipe w/ two hi-flow cats and FlowMaster 40s.
This setup was okay, I liked the fact that it was LOUD, it felt like I didn't have any cats at all. But...I was losing some of my back pressure. Plus the ride quality feels like you're gliding through air.
My current set up:
Stock cats/hi-flow cats/h-pipe/flowmaster 40s.
Not as loud as my first setup, but I got my damn back pressure!!! Still sounds good in my opinion. But I'm going to upgrade my exhaust system again.
