I was the other buyer of the other Magnaflow system that jackz and I purchased. Performance Peddler is an easy company to deal with- very smooth transaction. I got the system within a few days after placing the order. good thing shipping is free because the box was 50lbs.
the system itself is awesome. I really don't have any problem with the sound or the 2k drone. I feel that it is tolerable and I expect it to be on my vehicle for a long time.
btw, I have the 03 V8 sport ed, and the installation was fairly quick at the shop.
I did initially show an improvement in mileage after a reset. the computer showed 21.4 mpg (my comp is about 0.7 off w/ stock exhaust) and this is with a 74 mi roundtrip freeway commute. so that would mean I was getting about 20.7 mpg. I never got the chance to actually hand calculate since intallling the new exhaust b/c my commute has since changed and I now drive mostly city streets, the comp now reads 18.6
