Personally I'm all for making my vehicles easier to work on rather than try to get every last ounce of performance. How much can you really use on a street car anyway?
That was my thinking too, as i bought some of those chambered mufflers and will be redoing the exhaust system. The 3 inch H-pipe i have now hangs down and scrapes over speed bumps. So i was thinking of just going with straight dual pipes this time. I am going back to 2.5 pipes as well.
