So im looking at a Magnaflow SI/DO cat back exhaust for my 05 f150. The part number is 16520. I was wondering if anyone has any experience with this exhaust and what it sounds like cause i cant find any videos of the exact kit. The truck is a 05 f150 with a 4.6 ext cab. with 6.5' box, will this kit fit on my truck?

Is $400 resonable price for the kit
Thx guys
